How to put the clutch plate on a single axle tractor correctly

Further information

Quite often the inertia clutch is used. In it, the levers are connected to the drive shafts and are complemented by cams. These cams are driven by the force of inertia into the grooves placed on the cup-shaped coupling half. This coupling half is in turn connected to the drive shaft. Levers are mounted on a common axis that is positioned in the slot in the driven assembly.

Leading half-coupling is equipped with radial inertial pins. They rotate and act on the intermediate element at the same time. This element communicates with the machine shaft through a slot. In addition, the intermediate cup with slotted shank comes into contact with the axle, locking the levers in the clamped position. They must be held on until the machine shaft is unscrewed.

But still most people prefer the familiar disc clutch. For it to work well, you will have to adjust the part immediately after installation. the adjustments are repeated at a later date in the course of operation, at approximately equal intervals. Make sure that the pedal moves freely. If the adjustment does not help, consistently check it:

Awareness of how to correctly and which side to put the clutch disc when repairing or replacing the node, will help to avoid repeated disassembly of the unit, prevent the occurrence of additional malfunctions of the car and its elements. Thanks to the clutch vehicle can start smoothly without overloading the power unit, contributing to the normal and continuous operation of its units and components of the gearbox.

Disc replacement is usually done together with the whole clutch basket. There are two ways to do the job: with and without disassembling the gearbox. The latter method is less time consuming and more convenient. The work process is performed on an elevator or inspection pit.

Variety of clutch designs for tractor mini machines

There are several classifications of clutches for minitractors. Let’s consider the most common ones.

Depending on the mechanism for transmitting torque to the gearbox of a mini-tractor, they come in different versions:

The former, which is most commonly found in factory modern models of mini-tractors, has 3 components:

Speed is transmitted by friction between driving and driven parts. Friction clutches are also called mechanical clutches. Their performance is governed by the frictional properties of the parts from which they are made, and various friction pads that change the friction force in one direction or another can be used to enhance them.

In electromagnetic ones, the motor and transmission are connected by a magnetic field or by the use of a special powder with magnetic properties. It activates the electromotive force and short-circuits the magnetic field between its components.

The work of hydraulic clutches is based on the force of a working fluid flow, which acts on the driven parts of a minitractor. If the force of the flow is constant throughout the work, they speak of hydrostatic couplings. If variable (dynamic), however, it is a hydrodynamic clutch.

Hydrodynamic clutches are prevalent in most modern high-power tractors because they wear the transmission less and cause smoother operation of the entire traction unit.

According to the number of discs the clutch is classified into:

The basic element of the multi-disc clutches is the housing with a notched inner surface. It is in it that the discs with grooves on the outer circumference will be inserted. They freely rotate along the axial path and consistently transmit torque between the gearbox and the engine flywheel.

Making a clutch mechanism with their own hands

There are two essential steps before assembling the machine: studying the drawings and selecting the parts. The drawing should be as clear as possible, and all the components marked on it should have a full size marking and indication of their places in the device.

To make a homemade mechanism, the following parts are needed:

Ready-made clutch, made for a motor-block with your own hands, will work well, for example, for motor-blocks Argo and Neva MB-2. Users note that such a mechanism is of good quality and is quite durable.

The mini-tractor clutch or as it is simply called. clutch. is an indispensable part of every tractor unit. Not an exception and minitractors, where this detail performs a similar function. to evenly connect and separate the motor part and the working gear. In other words, the minitractor clutch takes the torque of the traction part. the internal combustion engine. and relays it to the transmission. Among other things, the clutch protects the mechanisms of the transmission from malfunctions that can occur in the case of a sudden increase or decrease in torque. Factory equipment, which is supplied to the market, has a ready and debugged clutch. When it comes to self-made mini-tractors, this question has to be solved independently. Let’s dwell in more detail on the varieties of clutches for the minitractor and how and from what they can be assembled with our own hands.

Clutch of a power tiller: construction, adjustment with your own hands

The clutch. this is one of the most important elements of a modern power tiller, whose main function is to transmit torque from the crankshaft of the machine to its gearbox. It is the quality clutch for your power tiller that allows the machine to move smoothly and stop, if necessary, without the need to shut off the engine completely.

Regardless of the class of the power tiller, the clutch consists of the same parts in its standard design.

The release lever generates a signal when the clutch locks. At the same time, the latter disengages the driving element from the pressure plate, resulting in a complete disengagement of the existing clutch in the power tiller unit.

The automatic clutch for a power tiller is fitted with a bearing that acts as a friction reducer. It allows the linkage arms to rotate without coming into contact with each other or the fixed linkage when the power tiller is in operation. The spring built into the clutch ensures that the steering mechanism returns to its original position after each gear change cycle.

Making a clutch for your power tiller with your own hands

In continuous use, clutch components are in constant motion and subject to wear, so even the most robust parts will eventually wear out. Over time, you will have to buy new parts or make everything with your own hands.

Before you make a clutch on a single axle tractor, it is worth to get the following spare parts:

  • flywheel and the primary shaft (an old gearbox from a Soviet Moskvich will do);
  • the idler pulley with two knobs;
  • a steering knuckle and a serviceable hub (can be taken from the Tavria car);
  • A crankshaft (GAZ-69);
  • B-profile.

5 Tips For Replacing A Clutch

It is worth first considering the drawings of the structure of the clutch. This will make the job a lot easier.Homemade clutch is made according to the following scheme:

  • Grind the crankshaft until it will not touch the internal parts of the equipment;
  • Nasazhivaetsya original hub on the shaft;
  • Ground on a shaft the place under the bearing. The hub is installed without backlash, so that the pulley turns freely;
  • Turned crankshaft, and perform the same steps on the other side;
  • Make six holes at regular intervals in the pulley drill with a five-millimeter drill bit. Ten-millimeter bolts are screwed into them;
  • The pulley is installed over the flywheel, the elements are fastened with bolts. The places for the holes are marked, taking into account their coincidence with the pre-drilled holes;
  • The pulley is pulled out and appropriate holes are drilled in the flywheel;
  • The inner surface of the flywheel and shaft is ground until the parts are no longer in contact;
  • It is necessary to have a clutch handle on a singleaxle tractor. Takes a tube with a length of 30 millimeters and a diameter of 10 millimeters, it is attached to the pulley;
  • The clutch cable for the tiller can be taken from an old chainsaw. It is wound on a spool.

Independently prepared clutch can be installed on the following brands of power tillers: Agro, Neva MB-2, Kaskad.

The clutch is one of the most important elements of a modern power tiller whose main function is to transmit the torque from the machine’s crankshaft to its gearbox. The quality clutch integrated into the design allows the harvesting head to start and stop without having to stop the engine completely if necessary.

Regardless of the class of power tiller, the clutch consists of the same parts in its standard design.

When the mechanism locks, a signal is emitted from the release levers. The latter disengages the slave element from the pressure plate at the same time, resulting in a complete disengagement of the existing clutch in the power tiller.

The automatic clutch on a domestic tractor is fitted with a bearing that acts as a friction reducer. Thanks to its presence during the work of the engine block the arms rotate without touching each other and the stationary drawbar. The spring integrated into the clutch mechanism ensures that the control assembly returns to its initial position after each gear change cycle.

Making a clutch for a motor-block with his own hands

In continuous operation, clutch parts are in constant motion, and wear out, so even the most reliable elements will wear out over time. Over time, you will have to buy new parts or make everything yourself.Before you make a clutch for a singleaxle tractor, you need to get the following spare parts:

  • Flywheel and the primary shaft (suitable old gearbox from a Soviet Moskvich);
  • The clutch is made by a slave pulley with two knobs;
  • A steering knuckle and a serviceable hub (you can take from the car Tavria);
  • The clutch is made from a crankshaft (GAZ-69);
  • B-profile.

It is worth preliminarily to consider the drawings of the clutch structure. It will greatly simplify the work.

Homemade clutch is made according to the following scheme:

  • Grind the crankshaft until it will not touch the internal parts of the equipment;
  • You put the original hub on the shaft;
  • The place on the shaft for the bearing is ground. The hub is mounted with no play so that the pulley can wrap around freely;
  • The crankshaft is turned over, and the same steps are performed on the other side;
  • Make six holes at regular intervals in the pulley with a drill and a five-millimeter bit. In them will be screwed ten millimeter bolts;
  • The pulley is mounted over the flywheel and the elements are bolted together. Mark the places for the holes, taking into account their coincidence with the pre-drilled holes;
  • Pull out the pulley and drill appropriate holes in the flywheel;
  • The inner surface of the flywheel and shaft is ground until the parts are no longer in contact;
  • The clutch handle for the single axle tractor is required. Takes a tube with a length of 30 millimeters and a diameter of 10 millimeters, it is attached to the pulley;
  • The clutch cable for the tiller can be taken from an old chain saw. It is wound onto the spool.

Independently prepared clutch is possible to install on the following brands of power tillers: Agro, Neva MB-2, Kaskad.

The clutch for a power tiller, as in any other agricultural-type equipment, consists of such parts:

  • direct control assembly. The squeeze lever is connected to the pressure plate by a pedal lead and rods;
  • of the drive unit. A bearing reduces friction, the levers do not touch during rotation about their axis;
  • driving components. A spring returns all mechanisms to their original position. The backhoe is pushed away from the levers to the distance needed to turn the machine off.
