Starter for power tiller. the device of manual and electric

Motor blocks are known for their design features. In particular, the fact that they use two starters at once. The auxiliary or spring starter helps the main one to start quickly and properly. But if the auxiliary starter suddenly fails, you have to think about how to repair the manual starter. Perhaps even with their own hands.

Incidentally, the spring version is not the only. The manual starter on a single-axle tractor is quite common, it is common in Russia. It is much easier to use. It is easier to install, even if the user does it with his own hands. It has quite an uncomplicated design:

  • drum housing;
  • coil;
  • Spring, or rather, the whole two: large and small;
  • washer;
  • cord;
  • tongues;
  • bolts and nuts, without which you can not assemble either mechanical or electric starter.

When assembled, it looks as follows: the cord is attached to the reel, and it is fastened to the core of the reel housing. There is a special space inside the drum, where a large spring is located around the axis. It is responsible for ensuring that after cranking, the starter returns to its previous position.

Structure of the starter

The starter to the motor-block. it is, at first glance, a complex mechanism, but, in practice, there are no complicated elements in its structure. These devices act as the starting component, with which the internal combustion engine is started. The work of the device consists in the fact that a pull is created for the rotation of the crankshaft and camshaft. In addition, at this moment a spark is supplied to the glow plug, which allows to form the necessary traction in the combustion chambers for the subsequent independent operation of the engine. In practice we can distinguish the following variants of starters for power tillers:

In each case, the principle of operation is similar, but the starting procedure differs significantly. If the first case, it is done manually, the second version is performed electronically, with his hands turned only a key in the ignition mechanism, or run from the button. Most old power tillers are equipped with a mechanical manual starter, which is why it is necessary to consider in detail how, if necessary, to repair the device.

Important! Modern power tillers are equipped with an electric starter, but if it fails, you can also fix it yourself.

The device of the manual version

Before considering how the repair of the manual starter for a motorblock is performed, it is necessary to consider what elements, consists of this accessory:

  • The body, made in the form of a drum;
  • Inside there is a large and small springs;
  • additionally there are tongues and a washer;
  • coil for starting and starter cord;
  • elements used for fastening.

All elements are made of resistant materials in order to guarantee maximum resistance to wear and tear. The fixture is started by a spool, which is driven by a cord. In some cases, the former models of power tillers were equipped with special footrests for starting, like motorcycles. Repair of kickstarter (starter foot) on a power tiller is almost no different from working with a manual mechanism, except for the presence of a special remote handle and internal cam mechanism instead of the coil and cord.

It is worth noting that the electric mechanism is also equipped with a similar device, but here there is a more complex technology.

Electric starter device

As previously stated, this part has a similar device to the manual version, but differs in the fact that it also includes drive brushes, cam mechanism, wiring and electric drive. The last component simulates the mechanical forces that are created by the incoming electric power and the built-in electric motor. All other elements are similar to each other and provide the same function, namely, to start the engine by rotating the camshaft and crankshaft.

Important! An additional difference between the elements is that when repairing the equipment and disassembling the device, you also need to disconnect the electrical supply wires.

How to repair the starter motor-cultivator with your own hands

Let’s consider how the repair of the starter motor-cultivator with your own hands. Before you start repairing the manual starter, you need to find the manual for its operation, which contains a diagram of the device. Then a wrench must be prepared to open the mechanism.

Before you start disassembling the unit, you need to take pictures of it so that you can reassemble all the parts and components correctly later.

After that, unscrew the washer, which is located in the middle of the housing. After opening the cover, you must carefully examine all the parts that are located inside the drum and determine which of them are damaged. It is necessary to inspect small parts very carefully and carefully, so as not to accidentally spoil them and not to lose them.

In most cases, the repair kickstarter on the tiller is to upgrade the components that failed. For example, replacement of the starter cord is performed if it is torn or frayed.

If the big spring is out of order, it is necessary to remove it from the drum. There are usually hooks on the places where the spring is attached. If there are none in the design, it is necessary to heat the ends of the spring and bend them in the right direction. If the spring is completely out of order and there is a pronounced fatigue of the metal, then there is no need to try to return this spring functionality. In this case it is better to change it. After that the machine is set in place.

In addition to the manual starter there are spring and electric starters on single axle tractors. The spring mechanism is of a simple design and is easy to start. The machine starts after moving the tiller handle. The acceleration of the motor occurs through the semi-automatic work of the spring. You can replace the manual starter with a mechanical one yourself.

The electric starter on the power tiller is connected to the battery which it draws its power from. The electric start of the device is carried out by means of a starter button. Battery determines starter power and working time. Installation of the electric starter is made according to the circuit diagram of this design. Single axle tractors with electric starter are durable, reliable, long-lasting.

Unfortunately not all manual mowers can be converted to a spring or electric mower. Therefore, before starting work on replacing the manual mechanism, it is necessary to study the manual and the capabilities of the power tiller and find out whether such a conversion is possible.

Farmers should know that all power tillers work properly in the beginning. On an assembled machine various components gradually fail. In order to prolong the service life of the walking tractor and all its parts and assemblies, it is necessary to regularly check the mechanism and properly care for it. All assemblies and components must be periodically lubricated with machine oil and checked for proper operation. In order to increase a cultivator’s productivity and extend its service life, proper care of the machine is necessary at all times.

How to repair the manual starter for your power tiller with your own hands?

The main thing is to be very careful with all the small items so as not to lose them. Most often, the repair of the starter involves the renewal of unusable parts. For example, the replacement of the starter cord will be relevant if it is completely frayed or torn.

With a large spring, everything is somewhat more complicated, because at the ends of the attachment points there are special hooks. If they are missing, it is necessary to heat these very ends and bend in a suitable direction. An important point: do not try to restore the element to its former functionality when there is a pronounced metal fatigue. Replacement will be the best way out.

Design of the manual version

Before considering how to repair the manual starter for a motor-block, it is necessary to consider what elements this accessory consists of:

  • The housing is made in the form of a drum;
  • Inside there is a large as well as a small spring;
  • additionally there are tongues and a washer;
  • coil for starting and starter cord;
  • elements used for fixing.

All parts are made of robust materials for maximum durability. The attachment is started by a spool, which is driven by a cord. In some cases, older models of power tillers were equipped with special starter cords, like motorcycles. Repair kickstarter (starter foot) on a power tiller is almost no different from working with a manual mechanism, except for the presence of a special remote handle and internal cam mechanism instead of the coil and cord.

It is worth noting that the electric mechanism is also equipped with a similar device, but here there is a more complex technology.

All other elements are similar to each other and provide the same function, namely, to start the engine by turning the camshaft and crankshaft.

Important! An additional difference in the elements is that when repairing the equipment and disassembling the device also requires disconnecting the electrical power cords

Small nuances on repair

As already mentioned, the manual starter is the least fussy. In most cases, the starter repair is to fix the place where the springs are fixed. They are sometimes unbent. Or, perhaps, the repair of the starter will be to replace some parts with new. Sometimes you need to replace the starter cord.

In order to determine the specific malfunction, you will need to disassemble the area of the power tiller where the starter is mounted. In what order the repair should take place:

  • You’ll need the diagram from the manufacturer to get started. It describes how and where all the parts are attached to the power tiller. You’ll also need a wrench to unscrew and remove the nuts.
  • Next, you need to disconnect the starter. It is better to take pictures and write down everything about its mounting scheme. Otherwise you might not be able to put it back together.
  • In the center of the drum you will see a washer that must be unscrewed. This is the top washer. When you take it off, take apart everything you find inside and check if anything is damaged.

Repair of motor-block starter with his own hands

Despite the high quality and reliability of modern starters, some owners are sometimes faced with the need to repair them. Most often the breakage of the mechanism is insignificant, which allows you to quickly fix the problem with your own hands. The order of disassembly and further repair of the mechanism is as follows:

spring, power, tiller, starter
  • Start repairing the unit by studying its diagram. If the design of the motoblock provides for an electric starter, then before dismantling the mechanism, you need to familiarize yourself with the location of its terminals;
  • Using a wrench from the motoblock kit, unscrew all the screws and nuts holding the mechanism in the structure of the motoblock;
  • If you dismantle the unit for the first time, we advise you to take a picture of the starter before finally removing the mechanism from the machine;
  • Next, unscrew the washer located in the central part of the drum housing and carefully inspect the internal parts for breakage;
  • All further steps depend on the malfunction of the starter parts. If the cord has failed. it is frayed or torn, then to replace it you will need to wind a new product, adhering to the marks on the reel housing of the mechanism;
  • Another common breakdown. it is a failure of the spring, or rather. its tendrils, the edges of which should be bent in the form of hooks. If the tendrils are torn, then the edges of the spring will need to heat and bend them so that the spring can be hooked into the holes in the drum. In this case of great importance is the remaining length of the spring. make sure that the part does not stretch too much. If you find that the spring is very short, or it has already begun to rust, it is better to replace it entirely.

Before mounting the starter back on the single axle tractor, it is a good idea to first clean. This will prevent debris from getting inside the motor, carburetor, and spark plug.

Single Axle Tractor Manual Starter Design

The cord itself is fixed on the reel mounted in the central part of the reel. A special large ring spring is placed in the drum around the axle and helps return the spool to its initial state after cranking. As you see, to assemble such a mechanism is quite simple.

As for the working process, it is even simpler: after a person sharply pulls the starter knob, the mechanism itself takes effect and transmits the initial rotation to the engine. To get a better start, it is necessary to pull the lever twice.

But, as it usually happens, nothing works forever and even such reliable devices sometimes break down. Anyway, do not get upset, because all the problems can be solved.
