How to assemble the lawnmower starter spring. Starter assembly
Lawnmower starter diagram
Disassembly-assembly of the starter is not a serious problem, just requires a little skill in handling a screwdriver and most importantly observing some safety precautions:
Unscrew the screw securing the pulley to the starter cover. Remove the two tendrils and spring, and then extremely carefully, turning the head to the other side, dismantle the pulley. The specifics of this operation are such that even with careful removal of the pulley, the spring instantly pops out of the coil turning into a sharp metal strip that can injure the repairman. Analyze the nature of the failure. If the spring is completely destroyed, the only correct solution is to replace it. You can easily buy a defective part in online stores that sell starters and spare parts. If the spring is just out of mesh, it should be inserted into place, bending the tendon beforehand. This should be done carefully, since it is a tin and if not handled carefully, it could break at any time. 2. After putting the spring back in its groove, take your time and, holding it with your finger, begin twisting it. Pay close attention to safety, because if the metal strap falls off, it may cause injury. To tuck the spring in from the first time is not easy, some experience is required, so if you fail, it needs to repeat it more than once. 3. After the spring is wound, continue assembling the starter. Carefully turn the coil and insert it so that the bend of the spring fits into the special groove in the body. 4. Put a washer under the screw. insert the spring and the washer again. After that, insert the cup with the tendrils and tighten everything with the screw. Starter assembled. It is necessary to pay attention to such a nuance as the installation of the washer. It should not be skipped in any way. If it happens, the spring will scratch the plastic cup on which with time there will be a notch and it will be pressed tighter by the screw and jammed. As a result, there will be a feeling that the spring is off and needs to be repaired. This defect can easily be corrected by replacing the spring with a longer one or by installing an additional washer. If at hand is not a spring or a washer, you can loosen the screw and the starter will work without jamming. But this is a temporary measure, with prolonged use of the screw will unscrew and lose, which is fraught with loss of spring and failure of the starter as a whole. The next step is to tension the spring. To do this, it is necessary to remove the handle from the starter rope. Next, without coiling, insert the rope into the designated slot in the coil. Tighten the spring directly. To do this, turn the spool counterclockwise. in the direction opposite to the direction of rotation of the spool when you are winding the rope. The number of turns should be the same as the number indicated on the starter model and the length of the rope. After the required number of revolutions is done, we pass the end of the rope through the hole in the starter cover, install the handle and fasten it with a knot. It is better to do it together with an assistant so that the end of the rope doesn’t wind up inside the starter. If after the repair the spring has come off again and the chainsaw cannot be started, you will have to repeat the repair procedure. But first do an upgrade of the starter. There are two ways to get rid of a slipping spring. The first is to use an additional metal strip, the second is to drill the coil ( photo) and fix the edge of the spring with a wire
It should be noted that today there are two main types of starter for lawn mowers to buy in any store: electric and manual. Today, manual starters are more popular. In addition, according to the principle of operation, starters are divided into direct action, combined and inertial.
Concerning the starter motor’s working life, there is no simple answer. Here, of course, you should proceed from how and with what force you will handle the machine. So you see that the starter plays an extremely important role in the function of the entire grass trimmer.
However, you should be prepared for the fact that the starter for the lawnmower, like any other part, is prone to failure, but the frequency with which you will repair or replace the starter, depends entirely on your treatment.
The main faults of the grass trimmer starter
Determine the cause of the failure of the starter is not difficult. There are several basic options:
The above information is pictured below.
It is possible that the starter mechanism will break by accident. The consequences will be unfortunate if the broken cord is wound around the flywheel of the engine: the spring will break, the pulley will come off. But such cases, when you need to replace the starter unit completely, are very rare. In most cases, to fix the mechanism, it is enough to put a new spring or replace the cord.
Manual design is simple, but it can be improved to save effort and time. For example, an electric starter for your power tiller. Then you won’t have to pull the handle every time. But keep in mind: this design does not work with all manual starters. And the circuit you choose to install may not be suitable for every engine.
In these cases, you should consider a third option: a spring-loaded engine start mechanism. After installing it on the engine, you just need to move the handle of the power tiller, and it will immediately start. This type of kickstarter is based on semi-automatic spring operation. It accelerates the engine mounted on a single-axle tractor without having to pull the handle with your hands. It can take about two hours to change from a full manual starter to a mechanical one.
Creating marketing materials and marketing strategies for friends and relatives
Remember, the first contributors to your project will be your friends and relatives.
Divide your acquaintances into the following groups: close friends / relatives; people with whom you are friends but are not in constant contact; people who are friendly to you and acquaintances.
Sketch out a specific message (for or email) for each of these groups that you will address to each person, depending on the segment they fall into. When you send these messages, be sure to back up each one (especially for friends and family) with a text message or phone call to thank them or remind them of your project.
Now that you have identified your base of early supporters/contributors, you need to start creating a reward system that will allow them to show their support.
How to tension the chain saw starter spring
Starter for chain saw. To quickly start any chainsaw you need a starter.

How to install or replace the starter springs on brushcutters, brush cutters and grass trimmers
But what can we do if we have everything alright with the rope, but the spool (pulley) of the starter does not unwind?? Let’s consider this question step by step on the example of the starter gasoline motor auger ADA GroundDrill, which has a pulley with two metal tendons on 2 hooks.
In the case of other types of manual starters of similar design, which are widely used in petrol brushcutters, trimmers and power drills, the whole process of repairing the starter will look similar, differing only in some nuances.

In case the starter spring is just torn off, t. е. One of the hooks came out of the catch, it is enough to insert it, if necessary, slightly pressing the hooks tighter (just do not break off!) Put the spring with outer hook into groove of the pulley and start twisting it, at the same time holding it with fingers inside the coil and not letting it come out.
Pressing the spring against the pulley, coil the spring inward in a circular motion
At first glance, it may not seem easy to insert the starter spring, but everything comes with experience. With a little practice you can easily wind the spring in a pulley in about a minute.
Removing and disassembling the starter, replacing the broken parts
To repair the grass trimmer starter, you must first disassemble it and then reassemble. The process is not particularly difficult. You will need to work the form of a screwdriver.
Care should be taken to ensure that the spring does not injure the owner by accidentally pulling away.
Disassemble the starter mechanism to install new parts to replace the broken parts in the following order:
unscrew the screw securing the pulley with the starter cover using a screwdriver; remove the spring and the tendrils; carefully remove the pulley (you must turn your head or practice, wearing goggles and gloves beforehand); determine why the trigger is triggered; if the spring has almost completely broken, it is replaced; when the spring is out of the hook, install it in place by bending the antenna in front (the pictures show the installation process);
Spring Starter Breakdown
Insert the spring plate into the groove and screw it carefully.
To replace the spring, the work must be done with care and caution: it may accidentally explode under the force of its actuation. Even if you remove the roller carefully, the spring band comes off the reel very quickly and can injure your hand with its sharp edges
Immediate replacement of the spring plate does not always work. This often slips, so attempts must be repeated to achieve the desired result.
The assembly of the starter is carried out in several steps:
The coil is turned over, installing it so that the bend of the spring fits exactly into the groove of the housing, as in the photo below;
To do the above manipulations it is necessary to put two washers. Failure to do so can cause damage to the plastic cup over time, and it will begin to jam when it is removed. It makes it seem like spring has come. To correct this flaw, you need to install this longer piece or an extra washer.
When such parts are missing, there is only a little unscrewing the screw, and the starter assembly will start to work without fixation. But this option is temporary. it is better to repair it as soon as possible.
After installing the spring, tighten it. To do this, do the following steps:
- remove the handle from the starter rope;
- then insert the rope into the groove of the spool;
- The spring is tightened by turning the coil counterclockwise (winding);
- Perform the required number of revolutions specified in the instruction manual of the grass trimmer model used and the length of the cord used;
- at the very end the rope is lowered into the hole in the starter cover;
- place the knob in place by locking it with the knot.
If the spring continues to fly after repairs, you can get rid of it in the following ways:
- insert the appropriate piece of plate into the slot where the spring hook is located;
- Drill holes on both sides of the groove in the spool to insert the spring hook and secure it with wire.
Replacing a torn cord
Replace the broken rope in the following order:
- The old rope is removed;
- choose the right size (thickness and length) of rope;
- Pass it through the special hole in the coil, tie a knot;
- Inflate the spring, making the necessary number of revolutions;
- fix the handle
It is better to tighten the spring plate with your Rartpeg, so that the edge of the cord does not bend inside the starter mechanism.
Assemble the starter for the grass trimmer and tighten the spring is not difficult, but you need to do it carefully and cautiously. For different models of gasoline brushes, starter mechanism failures are the same, so they are repaired similarly
There are some nuances associated with their design features.
One of the key parts of the grass trimmer is the starter, designed to make it easier to start the engine of the device. Like other parts, it periodically breaks. In this case, there are two solutions to the problem: repair the starter grass trimmer or replace it completely. The second option is easier, but more expensive. In addition, you must first find the necessary part on sale, since different models of lawn mowers use different starters. If you have free time and a screwdriver with the appropriate tip, you can repair it if you know how it works, what defects are characteristic of it and how to fix it. It’s all here.
Replacing the oil seals
How to repair your STIHL 180 chain saw if the oil seals need replacing? It is necessary to disassemble the engine, which first requires removing it from the chainsaw. To remove it, follow the procedure described under: “The STIHL 180 chain saw control knob is broken. how to fix it”.
Once the engine is removed, unscrew the 4 screws securing the engine sump, and then it is removed. Thus, after removing the oil pan, we get access to the oil seals and bearings of the crankshaft.
The most important thing when replacing oil seals is to reinstall them and seal the oil pan properly.
How to replace or reassemble the starter spring?
If the rope on the starter turned out okay, the suspicion falls on the coil itself. It is powered by a coiled coil spring. There are certain steps to change the spring.
- Remove the starter motor from the lawnmower.
- Remove the starter coil.
- Unscrew the main bolt that holds the pulley to the housing.
- Pull out the take-up clamps and the spring, the belt spring is almost completely straightened out or coiled up by rings of larger diameter.
- Hold it in place beforehand.
- Check if the spring is intact (there can be rusty spots, breaks, etc.). д.). If the hooks on its ends are broken, you can’t bend new ones. high-carbon steel breaks when you try to bend it. Loose hooks are suitable for easy bending.
- Make sure the auxiliary (regular) spring and washers are in place. These parts protect the coil body from being ground by the ends of the main spring. If the washers and spring are broken and no new ones are available, do not screw the coil bolt tight, but keep an eye on it. it can unscrew and lose.
- If the main (flat) spring is damaged, insert a new one. Put a catching hook on the end of the spring on its place and bend it, inserting the coil by coil in the space where it should be.
