Valve Adjustment On A Gasoline Tiller

The chassis of the unit consists of wheels. They are pneumatic and metal. Wheels are installed on the frame, along with the rest of the block.

On the handles and around them are the details of the accounting (software) management. These are the clutch lever, various levers and buttons for configuring the direction of travel, for shifting gears. At the same stage there is a button for stopping the motor.

Adjustment of devices Neva mb 2, Zirka 105

The process of adjusting valves on the neva mb 2 tiller and a similar zirka 105 tiller:

  • Let the engine run, and then cool down a little.
  • Remove the cover.
  • We remove the valve cover and get to those flywheels that are under it.
  • Unscrew the lock nut.
  • The blade that we insert into the gap must pass very freely between the piston and the valve.
  • Screw the whole system back.

Setting gaps

Adjusting the engine valves means setting optimum clearances. Their norm is indicated in the technical passport of the tiller. Each model has its own permissible parameters, which depend on the brand and type of machine motor.

The permissible valve clearance on the chiller for a standard unit is as follows:

  • For the inlet valve. 0.10-0.15 mm;
  • For output. 0.15-0.20 mm.

To configure them, you need the following tools:

  • Spanners;
  • Styli for 0.10 mm, 0.15 mm and 0.20 mm;
  • Flat screwdriver.

The algorithm for setting the optimal clearances is as follows:

  • The engine must be cold during operation.
  • Disconnect the oil bath cup from the air filter and filter element.
  • Take the key, unscrew the 4 bolts around the protective cover.
  • Remove the starter, then the tiller flywheel guard.
  • Fix the “dead center” on the end of the flywheel. The mark on the cylinder blowing rib must correspond to the flywheel zero mark.
  • Carefully remove the valve cover with a paronite gasket, after unscrewing the 3 bolts.
  • Check the clearances:
  • There is an inlet valve near the filter;
  • Day off near the muffler.

To check the interval, insert a feeler gauge between the rocker arm and the valve. If the distance is more or less than the permissible, using a spanner wrench and a screwdriver, adjust the elements.

  • Wipe all joints of the mechanism with a clean cloth.
  • Reassemble the structure in reverse order.
  • Turn on the tiller, check its performance.
  • If the valves are adjusted correctly, the engine will run without noise, jerking or malfunction.

    The relationship of the engine and valves

    tiller is a complex agricultural unit that includes the following components:

    • Engine;
    • Transmission;
    • Running system;
    • Steering;
    • Supply system.

    The engine is the power mechanism of the tiller. There are such types of motors:

    • By picking method:
    • 2-stroke;
    • 4-stroke.
  • By the type of fuel used:
    • Diesel;
    • Gasoline.
    • Manufacturing plants have recently been producing high-performance 4-stroke motors.

      Diesel engines are installed on large units, gasoline engines, which are widespread among farmers, with a capacity of 4-9 hp, are installed on small and medium-sized units.

      The internal combustion engine is the main device in which the process of converting the thermal energy of fuel combustion into mechanical energy takes place.

      The energy transformation process is carried out in 4 stages:

      • Fuel launch;
      • Compression of the combustible mixture;
      • Combustion;
      • Release.

      Fuel material enters the combustion chamber through the inlet distributor. The valve elements are closed, the piston moves upward, compressing the working mixture. When the spark plugs are turned on, the discharge ignites the combustible material. As the temperature rises, the mixture expands, pushing the piston downward. Thermal energy is transformed into mechanical energy. When the valves open, gases are released into the exhaust system.

      The reason is the wear and tear of the elements. A small gap changes the phases of gas distribution. The engine does not run at its declared power. With a large gap, mechanical vibrations appear, which lead to deformations. Due to the short opening of the valves, the cylinder is not completely filled. This leads to malfunctions and malfunctions, reduced performance.

      Tiller valve adjustment is a mandatory procedure in carrying out maintenance.

      According to the technical regulations, it must be carried out once a year. In case of malfunctions in the machine, the valves can be adjusted 2 times a year.

      How to adjust the valves on the Lifan tiller

      Carburetor Tiller

      As for the carburetor, it is part of the engine power system. It acts as a kind of mixer that mixes liquid fuel with air to obtain a fuel mixture, which then enters the engine cylinders. Structurally, it looks like this:

      • Float chamber;
      • Diffuser;
      • Spray;
      • Throttle and air dampers;
      • Mixing chamber;
      • Jet etc.

      This is a description of the standard carburetor, but different tiller models such as Huter, Profi, Plowman, Champion, Carver, Husqvarna may use different carburetors, respectively, and the adjustment will be different.

      About the device of tillers and valves

      Tillery Cayman, Patriot, Texas, Foreman, Krosser, Viking, Forza, Sadko, Don are a rather complex technical device consisting of several main working units: engine, transmission, chassis and controls.

      The very understanding of the tiller design is very important, because the correctness of the repair and adjustment work depends on it.

      Let’s consider each node in more detail:

      • Engine. Depending on the configuration, 2-stroke and 4-stroke motors can be used. At the moment, it is the 4-stroke that is most widely used, because they have higher performance indicators.
      • In addition, engines are divided into diesel and gasoline. The former are most suitable for large-sized units, and the latter are most suitable for small and medium-sized units.

      For more details on the operation of the tiller engine, see the following:

      • Transmission. The torque that is transmitted from the engine to the wheels is carried out precisely by the transmission. It includes a gearbox, gearbox, clutch system and differential (for some models).
      • Depending on the type of gearbox and clutch, not only the cost of the tiller is formed, but also the principle of operation of these components.
      • Chassis. Most tillers have a pair of different types of wheels. pneumatic or metal, equipped with grousers. In addition, the undercarriage includes the frame itself, on which all the other elements of the tiller are located. the engine, gearbox, etc.
      • Control system. All tiller controls are located at the operator’s arm’s length, i.e. On the handle and in the immediate vicinity of it. This includes the clutch lever, gearshift and drive change buttons, emergency engine stop, etc.

      How to adjust the valves on the tiller

      Adjusting the valves on the tiller, setting up the control mechanisms, changing the oil in the main units, inspecting the tires are the main work that is carried out during the maintenance of the tiller. THAT is necessary to ensure the safe operation of the unit, check the reliability, strength of all its components and connections.

        Using the example of a motor vehicle engine of the Chinese company LIFAN, we will consider a number of problems, in the event of which it is also desirable to adjust the valves on the Lifan 6.5 hp tiller:

        • If “kickback” appears on the starter handle when starting the engine;
        • If you hear a distinct knocking in the cylinder head when the engine is running;
        • If the engine starts to work intermittently, it stalls and it is difficult to start “hot”, starting up properly only after cooling;
        • When there are pops in the muffler and the tiller loses power.

        How to adjust the valves on the tiller

        Tiller is a universal unit for plowing the land. Has gained wide popularity among farmers working on small plots, replacing a tractor.

        Valve adjustment on the Neva Tiller

        Take the Neva MB-23 model as an example and analyze sequentially how to properly adjust the valve clearances (the principle is the same for all tillers of this company). You will need 12mm and 14mm spanners, 10mm socket wrench, 0.15mm and 0.2mm styli.

        • Remove starter by unscrewing 3 bolts.
        • Carefully remove the muffler, belt and petrol engine guard.
        • Remove the valve box cover using a socket wrench.
        • Make sure what the valve clearance is on the tiller by looking at the instructions. For the Neva MB-23 engine, this is 0.15 mm for the inlet and 0.2 mm for the exhaust valves.
        • Adjust by measuring the gap with feelers and tighten the nuts, if necessary. When properly adjusted, the dipstick should fit between the valve and the rocker arm.
        • Reinstall the valve cover, belt, guard, muffler and starter.

        Correct Tiller Valve Adjustment

        Auto mechanic specializing in agricultural machinery

        For optimum performance of the vehicle, valve adjustment on the chiller is required. This procedure is mandatory and follows a special template. Different models have some features that need to be taken into account. If the tiller valves are adjusted, the gasoline engine must be fully prepared for further work.

        On Tiller Lifan

        Valve adjustment on a Lifan trailer has its own characteristics. There are several power options for the motor, which have their own clearance parameters. Mostly “Lifan 6.5” is used. The size of the gaps is set standard, that is, for the inlet. 0.15, and for the outlet. 0.2. The procedure itself is also carried out in accordance with the usual procedure.

        Lifan is one of the models that does not need to be warmed up before testing. The technology is warmed up after the valve adjustment, when all the systems are checked as a whole. Another important point is the ability to contact a special service, since the brand is widespread.

        Almost all Lifan modifications have a similar procedure. The only exceptions are self-assembly options that are created based on the model.

        How to adjust the valves

        Each model has its own characteristics for the valve regulation process. But basically there is a standard process that is not much different in the step-by-step version. Procedure:

        Valve Adjustment On A Gasoline Tiller
        • Preparation of equipment and necessary tools;
        • The casing is removed;
        • After the flywheel, remove the valve cover;
        • We regulate;
        • Installing the cover and shroud.

        The list of required tools may vary, depending on the brand and features of the motor. Standard requires a set of wrenches and screwdrivers, as well as a feeler gauge or small blade.

        The process itself involves setting the gaps to the optimal size. In almost any instruction manual, the value is indicated. Each option has its own mechanism with its own parameters. This must be taken into account during operation and maintenance.

        Together with the engine and all mechanisms, the transmission and chassis are installed. Only a full-fledged tuning process will bring the entire set of mechanisms to an optimal state.

        The setup itself includes the following steps:

        • After the valve cover is removed, the gap parameter is checked;
        • The correct backlash should freely pass the probe under the valve;
        • With the standard, the inlet type clearance is 0.15 mm, and the exhaust valve has a clearance of 0.2 mm;
        • To adjust, loosening the fastening nuts;
        • After achieving the result, the fastening nuts are tightened and the cover and casing are installed.

        All procedures are performed strictly by a specialist or a person with sufficient experience. Different options have different indicators, but the procedure itself is standard. With any diagnosis, it is also necessary to check all systems. Further performance and efficiency of the entire device depends on this.

        Various options for hand-assembled mechanisms depend only on the model range on the basis of which everything was assembled. Each type of agricultural equipment has its own level of parameters, which is necessary for effective work.

        Features of a gasoline engine on tillers

        The petrol engine on agricultural machinery is often the most problematic part. It has many features to consider when servicing and setting up. Features:

        • There are two types of gasoline engines. two-stroke and four-stroke;
        • Most of the parts are universal, but a number of mechanisms will require spare parts from the manufacturer;
        • A complete installation is carried out with maintenance, which is performed at least once a year;
        • Most of the engines are of Asian origin, but at the same time they are of sufficient quality and easy to maintain;
        • For adjustment and other processes, you will need to have the necessary tools.

        Here’s how to adjust the valve in the tiller:

        In the device of tillers, the internal equipment occupies an important place, since the productivity of any work depends on it. It is recommended to service the equipment annually in special services, but additional installation will also be required after a period of inactivity or after prolonged operation.

        This approach allows you to reduce wear on parts and keep your equipment in optimal condition.

        Any misalignment will result in reduced power, wear on parts and permanent problems. You can also find out that the procedure was carried out incorrectly by the lack of stability during operation.

        For each gasoline option, the verification process is governed by a number of points, including operational data, described in the instructions, as well as brands and types of sets of parts. With different types, the level of necessary parameters may differ even with one brand of the equipment itself.

        Valve adjustment has its own peculiarity

        On Patriot Tiller

        Valve adjustment on a Patriot trailer has its own nuances. It is worth considering that the Patriot has an identical Agro adjustment. The whole process is different from the standard plan, including for the Lifan brand. Setting:

        • Warming up the engine and cooling it down;
        • Removing the oil bath of the air filter;
        • Unscrewing the casing, including all six bolts;
        • The dead center (0) is located opposite the cylinder mark;
        • The cover is removed on the valve system;
        • Loosening the locknut and checking the backlash;
        • Setting the required result and tightening the nut;
        • Cover and casing installation;
        • Checking work.

        Using this system, you can vary the settings of the technique and adjust the required level of parameters.

        After completing the setup, a full check of the device is required during operation.

        The valves are regulated according to a standard plan that is provided for different models. Each type of engine has its own required parameters, which affects the features of the regulation. All requirements can be found in the instructions, as well as clarified in the service center, which is engaged in annual maintenance. Without a full inspection of the equipment, parts will receive additional wear and tear, and the equipment does not work efficiently.

        Tiller carburetor adjustment

        The instability of the tiller engine speed indicates that the carburetor needs adjustment. The need to perform this procedure, as a rule, arises before the start of the agricultural season, when the equipment has not been used for a long time, or vice versa, when the cultivator has been subjected to significant loads for a long period of time.
        Warm up the engine before proceeding with the adjustment. The work process itself looks like this:

        • The screws regulating low and maximum throttle are screwed in completely, after which they are loosened by about one and a half turns.
        • The motor is started with a starting device or manually, and warms up for about 10 minutes.
        • The lever that controls the operation of the power plant must be set to the minimum position. But the motor should not stop at the same time.
        • The throttle throttle adjusting screw will help to adjust the minimum idle speed so that the diesel engine is stable, without extraneous noise and stops.
        • The rotation of the screws makes it possible to precisely set the amount of combustible mixture that enters the motor.
        • Tightening the propeller enriches the mixture, while unscrewing it, on the contrary, increases the volume of air entering the engine.

        Using the idle screw, adjust the maximum idle speed. Proceed in the same way with minimum speed, using the throttle stop screw. The essence of such an adjustment is that the shutter screw allows you to adjust the angle to which it is closed.

        The lever responsible for controlling the motor should be moved to the “throttle” position. If the operation of the cultivator still cannot be called stable, the full throttle screw is adjusted until a perfect stroke is observed. However, the maximum permissible propeller speed is 2.5.

        The accuracy of carburetor adjustment can also be determined by how the spark plug looks after a short period of time under load. If the working mixture is ideal, then there will be no carbon deposits or traces of fuel on the candle, which indicate too poor or, on the contrary, too rich combustible mixture. It should be noted, however, that carbon deposits or traces of fuel on the spark plug may indicate not only incorrect adjustment, but also more serious problems of the Chinese or domestic tiller, including faulty ignition or cooling system.

        Tiller valve clearance adjustment

        Over time, with significant loads, the valve clearance of the tiller engine changes. This may be due to wear on parts. Insufficient distance leads to the fact that the stages of gas distribution change significantly. As a result, it is not possible to achieve a sufficient compression ratio, and the power device operates intermittently, without reaching the declared power. In particularly serious situations, even deformation of the valves can be observed. If the gap is too large, significant mechanical noises are recorded, the gas distribution phases also change significantly, the valves open for too short a time, due to which the cylinder does not fill properly, the power drops, and failures occur. Clearance adjustment is necessary as soon as the engine operation becomes incorrect or begins to occur with significant noise. Ideally, the engine being adjusted should be cooled down.

        So, first you need to get to the flywheel. It is on this part that the value of the top dead center is marked. The flywheel is hidden under the cover, and therefore will have to be removed. Before removing the casing, the oil bath of the air filter is removed. It is possible to facilitate the task in the process of removing the casing if you fix all the latches with rubber bands. All bolted connections are unscrewed with a key, after which the cover can be removed without problems.

        On the flywheel, you can see marks that indicate TDC, as well as values ​​of 5, 10 and 20 degrees. The 20 degree mark indicates the injection of the combustible mixture. The flywheel should be brought under the top dead center, focusing on the appropriate division. The valve cover is unscrewed and removed.

        In the process of adjustment, you need to use the following tools:

        • Screwdriver;
        • Box key for 10;
        • Blade 0.1 mm thick.

        According to the technical data sheet, the valve clearance of the tiller engine is from 0.1 to 0.15 millimeters, and therefore with the help of a blade it can be adjusted very precisely. However, you need to pay attention to the fact that some blades are 0.8 mm thick. and this is unacceptable. The exact value can be found with a micrometer or from the information on the manufacturer’s website.

        The adjustment is done as follows:

        • Using a screwdriver, we loosen the nut, insert the blade and begin to tighten.
        • We focus on the blade, carefully tighten the nut.
        • We adjust until the valve free travel is eliminated. It should fit snugly enough.
        • In the reverse order, we assemble the casing, put the oil bath in place by hand.

        If all manipulations are carried out without errors, then the engine will run smoothly and without unnecessary noise.

        Tiller adjustment: carburetor, valves, fuel system

        This article describes the adjustment of the tiller, namely its main parts: the carburetor, valves and the fuel system. This process is not easy, so we have also attached some photos and. You can also read repair tips here.

        Tiller fuel system adjustment

        If no fuel is supplied to the cylinder, the first step is to check if there is enough fuel in the tank. You also need to check whether it goes to the carburetor. For this, a hose is removed from the inlet connection of the device. If we are talking about a carburetor of the K45 type, you should press on its quench so that the fuel begins to pour out through the drain hole.

        READ  How To Make Tracks On A Tiller

        If fuel does not enter the carburetor, then you need to turn off the fuel supply valve, completely disassemble it and remove accumulations of dirt from the mechanical filter. To achieve maximum cleanliness, all components must be treated with gasoline. The fuel cock is assembled and returned to its original location.

        If fuel enters the carburetor, but is not supplied to the cylinders, it is necessary to check the correct operation of the fuel valve, as well as the presence of dirt on the jets.

        To deal with the carburetor of a gasoline tiller of the KMB-5 type, you need to remove it from the engine and pour out the fuel from the float chamber. Through the fitting (see figure), with the help of which the gasoline is supplied, it is necessary to supply the air mixture, having previously installed the carburetor in the operating position. The passage of air should go unhindered, and when the carburetor is turned over, it should completely stop. These features indicate the full performance of the part.

        Details in the figure: 1. fuel supply connection; 2. upper body; 3. throttle valve; 4. idle needle; 5. jet; 6. lower body; 7. air damper; 8. screw fixing the tie; 9. maximum gas needle; 10. spraying element; 11. float; 12. fuel supply valve.

        The fuel level inside the float chamber can be adjusted using the float tab. Ideally, it should range from 3 to 3.5 centimeters.

        To purge the nozzles, it is necessary to unscrew the screws responsible for full and low gas.
        Cleaning the carburetor parts begins by loosening the screws holding the upper housing. The lower body is removed, the fuel supply valve is flushed with gasoline, and the dirt from the nozzles is blown out by a pump. It is necessary to check if the float is intact. It is absolutely impossible to use rags in the cleaning process.

        After completing the cleaning, the housings are connected. It is necessary to check that the spray tube is clearly inserted into the hole located on the upper body. Open the throttle valve and check how well the assembly is done. The screws that secure the upper case are tight. After the assembly process is completely completed, the carburetor should be adjusted. This will significantly improve the performance of a heavy tiller with attachments, since perfect adjustment of all its parts is required for correct operation.

        If the carburetor DM 1.08.100 is installed on the engine of the cultivator, then the method for adjusting it will be as follows:

        • Screw in screw 10 (Fig. 3) at idle until it stops and unscrew it half a turn.
        • Then you need to tighten the full throttle screw 9 and completely unscrew it by 2 turns.
        • Unscrew screw 4 (Fig. 4) of the minimum engine speed right up to the stop of the lever against the bore of the carburetor body and tighten it by 2 turns.
        • Start the tiller engine, and then adjust stable operation at maximum rpm after warming up with screw 9.

        Do not disengage the engine control lever. Move it to the position of minimum throttle (revolutions) and, by unscrewing screw 10, set stable idle revolutions. This completes the setup.

        That, in principle, is the whole repair. The main points of adjusting the main parts of the tiller are considered. Use our manual (instruction) and prevent faults. Enjoy adjusting your tiller or cultivator!

        tiller is a two-wheeled unit with a UMZ-341 gasoline engine and a gearbox (4 stages).

        A feature of the technique is the ability to install not only standard attachments designed for the universal Agro tiller, but also home-made devices. Also, using this technique, you can transport up to 500 kg of payload. The maximum travel speed depends on the quality of the surface, but not more than 14-15 km / h.

        tiller consists of elements:

        • Engine.
        • Transmission.
        • Transmission units (gear reducer, clutch).

        Here’s how to adjust the valve:

        The operation of the Agro tiller is also facilitated by the presence of a reverse. With it, the technique, despite its significant weight (160 kg), has high maneuverability.

        The UMZ-341 engine is a single-cylinder, almost an exact copy of the Honda GX240. The motor is carbureted, the average gas consumption is 3-4 liters per hour, depending on the load and the intensity of operation.

        Adjusting valves on the Agro tiller: procedure

        The installation of the gaps between the valve and the rocker arm must be done on a cold engine, following the following sequence of actions:

        • Remove the covers that cover the gas distribution mechanism.
        • Check the reliability of the tightening of the head fastening nuts.
        • Set the piston to top dead center (TDC).
        • For the most accurate installation of the piston at the top dead center, it will be necessary to dismantle the protective fan casing and align the check mark “E”, which is located on the flywheel crown with the mark “G” present on the crankcase housing.
        • Unscrew the lock nut and rocker bushing. Then, by inserting a 0.08 or 0.1 mm dipstick between the fifth rocker arm and the end of the valve and without pulling it out, tighten the bushing so that the dipstick passes through the gap freely enough, after which you can tighten the locknut.
        • Check the thermal clearances between the rocker arm heel and the end of the intake / exhaust valve stems.
        • Replace the protective covers and secure them with nuts.

        In cases where the motor has been operating with a disturbed setting for a long time, a deposit consisting of incompletely burnt oil (coke) may form on the valve plane and the seat. In such cases, it is necessary to “fit” the parts, most often this operation is called “lapping”. The same operation is carried out when replacing the valve:

        • First you have to remove the block head.
        • Release the valves by pulling out the locking nuts and compression springs.
        • Clean surfaces from coke and rust using a knife or slotted screwdriver.
        • Flush parts with gasoline.
        • Apply lapping paste to the mating surfaces of the seat and valve.
        • In a circular motion, scrolling the valve with your hand and pressing it against the head, rub against the seat. This can be done using a drill or screwdriver.

        You can control the quality of work by eye. Valve lips and seats must have an even matt color.

        If Tiller Agro has worked for a long time with improper valve adjustment, there may be such a phenomenon as burning of the surfaces of parts. Most often in such cases, you will have to replace the damaged parts with new ones.

        During engine operation, the carburetor adjustment is also of particular importance; it is carried out after the timing is adjusted. It is important to monitor the oil level in the engine, timely replacement of oil and fuel filters.

        What is needed to regulate the Tiller Agro valve

        Auto mechanic specializing in agricultural machinery

        The products of the Ufa Engine-Building Plant are in well-deserved demand. Tilleri Agro are designed for agricultural work, cleaning garbage and snow, mowing grass, and transporting heavy loads. With long-term operation of this technique, the question may arise of how to adjust the valves on the Agro tiller.

        The fact is that over time, the factory settings are violated for a number of objective reasons, and incorrect adjustment leads to unstable engine operation, coking of the seats (a bushing pressed into the head of the block with which the valve comes in contact).

        In this article, you will learn how to adjust the valve

        You can adjust the gaps correctly with your own hands, without resorting to the help of masters. This will require little effort, but will save money, as well as learn how the engine works and how it works.

        It should be noted that timely repair and maintenance of Agro tillers will allow the equipment to work for a long time and efficiently.
