How to Insert a Spring Into a Trimmer Starter

How to repair a starter on a trimmer

Repairing the gas trimmer starter may be necessary at the most inopportune moment. At the same time, there are two ways to solve the problem: replace a broken part or change the entire assembly. The latter option will cost more. To repair the device with your own hands, in most cases you will need from the tools only a screwdriver with the appropriate tip. Repair work does not take much time and does not require special knowledge. It is enough to know the device, the principle of operation, the nuances of the assembly-disassembly of the starter on the trimmer to achieve the desired positive result.

The device and principle of operation of the starter on the trimmer

Gas engine. this is, in principle, the main part of the brushcutter. Its power lies in the range of 0.5-2.5 hp. The movement from it is transmitted to the shaft located inside the hollow rod, and then through the gearbox consisting of gears, already a fishing line or knife (working body).

Also, the brushcutters have the following elements:

  • protective cover;
  • lever;
  • a belt designed for ease of use of the device;
  • a starter used to start a gasoline internal combustion engine.

All details of the brushcutter are presented in the photo below.

The starter on the trimmer is an integral part that starts the engine to work. It is depicted separately in the two photos below.

Starter mechanisms of various models work on the same principle: during the start of the internal combustion engine, the protrusions marked with the number 1 in the photo above enter the hook with the dogs 3. When the engine starts to work, they return to their previous position due to the action of centrifugal force. A similar role is also played by wires 2.

The process of returning to the initial position of the elements of the mechanism occurs due to the presence of a spring wound around an axis. It unfolds when the rope is pulled. After releasing the cord, it is retracted and wound due to the folding of the spring. During the start of the internal combustion engine, the trigger mechanism rotates its shaft until it starts to work (starts).

Today, gasoline scooters equip Starting mechanisms of two types:

The first option is much more common.

How to Insert a Spring Into a Trimmer Starter

The starter on the trimmer can function without breakdowns for a long time. Unambiguously indicate the period of uptime is impossible. Everything is determined by the initial quality of the device and compliance with the rules for handling it.

The main malfunctions of the trimmer starter

It is not difficult to determine the cause of the breakdown of the starting device. There are several main options:

  • breakage of a cord (rope);
  • when the spring breaks or disengages.

The indicated details are shown in the photo below.

It may happen that the starter mechanism is accidentally broken. The consequences will be deplorable if a tattered rope is wound around the flywheel of an operating ICE: then the spring will burst, the pulley will rip off. But such cases when a complete replacement of the starter assembly is required are extremely rare. In most cases, to fix the mechanism, it is enough to put a new spring or replace the cord.

Removing and disassembling the starter, replacing broken parts

To repair the trimmer starter, you will need to disassemble it first, and then assemble it. This process is not particularly difficult. You will need to work shape screwdriver.

Everything should be done carefully, observing safety precautions, mainly so that the spring does not injure the master during an accidental departure.

Analysis of the starter assembly

Disassemble the start-up mechanism in order to install new parts instead of broken parts in the following sequence:

  • unscrew the screw fixing the pulley with a starter cover with a screwdriver;
  • take out the spring and antennae;
  • carefully remove the pulley (you need to turn your head away or work, having previously worn glasses and gloves);
  • determine why the trigger mechanism has broken;
  • if the spring has collapsed almost completely, then it is replaced;
  • when the spring exits the hook, it is installed in its original place by bending the antennae before it (the photographs show the installation process);
  • after the spring plate is installed inside the groove, carefully twist it.

To change the spring, work should be carefully and accurately: it can under the influence of the force caused by installing it in place, accidentally burst. Even if you carefully remove the roller, the spring band flies off the reel very quickly and can injure your hand with its sharp edges.

Immediately put in place the spring plate does not always work. It often slips, so attempts must be repeated until the desired result is achieved.

Starter assembly

The assembly of the starter assembly is carried out in a number of stages:

  • the coil is turned over, installing it so that the spring bend exactly fits into the groove of the case, as in the photo below;
  • stack two washers, between which a spring is placed;
  • put in place a cup with a mustache;
  • tighten the screw (photos below).

When doing the above manipulations, it is necessary put two washers. If this is not done, then the spring will eventually damage the plastic cup, and when it is pulled, wedging will begin. Because of this, a feeling appears, as if the spring has flown. To eliminate this drawback, you need to install this part of greater length or an additional washer.

When such parts are missing, you can just a little bit unscrew the screw, and the starter assembly will start to work without wedging. But this option is temporary. it is better to repair it qualitatively as quickly as possible.

Spring tension

After installation of the spring should it pull. To do this, perform the following steps:

  • remove the handle from the starter cord;
  • then the rope is inserted into the reel groove;
  • spring is tightened by rotating the coil in the opposite direction to the clockwise direction (winding);
  • make the required number of revolutions indicated in the operating instructions for the trimmer model used and corresponding to the length of the cord used;
  • at the very end, the rope is threaded into the hole provided for this, located in the starter cover;
  • put the handle in place, fixing it with a knot.

If after repair the spring continues to fly, you can get rid of this in the following ways:

  • cram a suitable piece of plate into the groove at the location of the spring hook;
  • Drill holes on both sides of the groove in the coil, into which to insert the spring hook and fix it with a wire.

Replacing a torn cord

A torn rope is replaced in the following sequence:

  • the old cord is removed;
  • choose a rope of suitable size (thickness and length);
  • passing it through a special hole located in the coil, tie a knot;
  • cock the spring, producing the required number of revolutions;
  • fasten the handle.

It is better to tighten the spring plate together with the partner so that the edge of the cord does not wound inside the starter mechanism.

It is not difficult to assemble the starter on the trimmer and wind the spring, only this should be done carefully and with caution. For different models of petrol brush, the breakdowns of the starting mechanisms are the same, so they are repaired in a similar way. There are some nuances associated with their design features.

But what if we have everything in order with the rope, and the starter coil (pulley) does not reel? Let’s take a look at this question step by step on the example of the ADA GroundDrill gasoline motor drill starter, which has a pulley with 2 metal antennae on 2 hooks.

In the case of other types of manual starters of the same design, which are widely used in gasoline trimmers, trimmers and motor drills, the entire process of repairing the starter will look similar, differing only in certain aspects.

Starter Repair: Disassembly

Unscrew the screw that secures the pulley to the starter cover. We take out the antennae, spring. Replacing the starter spring of the mower. The pulley itself is pulled out carefully so that the spring does not bounce into the face. Even with the most accurate dismantling, it usually flies out of the coil immediately and spins abruptly into a long iron strip or twists into rings.

Carefully insert the cup with the antennae into the grooves of the coil and tighten the screw.

Then watch that the washer located on a spring did not drop out. Why is it important? The fact is that the spring scratches the plastic cup with its end, as a result of which the latter wears out and begins to be pressed more tightly by the screw to the coil. Replacing the starter motokosa video. For this reason, a situation may arise that is very similar to a spring break: the handle is pulled out of the starter but does not return back. However, when loosening the starter screw, this problem disappears. To fix such a malfunction of the starter is simple: just pick up a spring of the same diameter, but a little longer, or put an additional washer. If we just tighten the screw slightly, it will twist and fly out, and this will increase the likelihood of spring breakage, since the pulley will not fit snugly against the starter housing.

They screwed the coil to the body, now we need to tighten the spring. Before this, it is necessary to remove the starter handle from the rope in advance. The device is a starter benzokosa interskol mkb 4325. If the knot is too strong, then you can just cut it off or try to untie it, for example, using a pair of pliers. This is done so that after you cock the spring, you can thread the rope into the hole in the starter cover. The second end of the rope must be secured in the coil before it is installed in the body; it is not necessary to wind the rope onto the pulley before pulling the spring; do this after.

Before you cock the spring, estimate how many revolutions of the coil the rope should be wound. Let’s say the length of the rope at the starter of the Ada GroundDrill-5 motor-drill is 5.5 turns around the coil. In this case, we make at least 6 revolutions of the coil in the direction opposite to the direction of winding.

So let’s get started. Without reeling, insert the rope into the groove in the reel specially designed for it. Replacing the mower starter cord. Everything is ready, proceed to pulling the spring. To do this, rotate the coil counterclockwise in the direction opposite to the direction of rotation of the coil when winding the rope. It is more convenient to do this not on the knee, but pressing the starter with one hand to the floor, and with the other turning the coil directly behind the rope attached to it. If experience is not enough, then the pulley itself can be rotated directly with two hands, but the rope will interfere with this, which can create additional inconvenience. Starter device for Husqvarna benzokosa. After the necessary number of revolutions is done, we pass the end of the rope through the hole in the starter cover, put on the handle, fix it with a knot. It is more convenient to do this together with a partner, so that the end of the cable does not accidentally wound up inside the starter.

By the way, on our own you can make some refinement in the design of the starter in order to more securely fix the end of the spring inside the coil. Then anyone has enough imagination. Now I will explain why this is necessary. It often happens that spring in starters of this type, after the first such independent repair and installation of the starter on the unit, after a few jerks flies again, the hook does not hold in the recess of the coil. And this despite the fact that the coil is almost tightly attached to the starter cover and the spring there should not be free to hang up and down, and even more so until the spring comes out of engagement. It turns out that when the cable is pulled, the spring pulls out, pulls out of the groove. In this case, you can do the following: cut a narrow strip of metal, which in thickness could be squeezed into the groove of the coil along with the spring hook itself. So the hook will not hang freely in the groove, which means it will not be so easy to break out.

Another solution to the problem: drill small holes in the coil on both sides of the groove and, having inserted the spring hook, fix it with a thin wire threaded through these holes. But here you need to manage to make sure that this wire does not touch when the starter cover rotates from the inside and thus does not brake the pulley. Alternatively, tighten the screw loosely or replace it with a similar slightly larger length. Starter benzokosa starter device. You can consider the option of installing some kind of gasket between the cover and the coil.

Chainsaw starter: device, breakdowns and DIY repair

In the design of the chainsaw, the starter is responsible for the proper starting of the tool engine. Over time, owners of chainsaws are faced with the need to repair this important component. And, the earlier it is possible to eliminate the malfunction, the less other important parts and mechanisms of the tool will succumb to wear.

The device and principle of operation of the chainsaw starter

Most well-known chainsaw manufacturers equip their products with starters that work on almost the same principle. Its essence is as follows: in the groove of the saw body there is a handle through which a cord is passed. With a sharp lifting of the handle, the cord is also pulled, which engages the drum, which is in the ratchet mechanism. By means of this, a drum with spitz, which is located on the shaft, is driven. During this, the crankshaft makes a couple of revolutions, which leads to compression of the fuel mixture, which at this moment is between the cylinder head and the piston. When lowering the handle, on the contrary, the ratchet and spitz lose their contact, which leads to a shaft stop.

With an increase in the power of the chainsaw, the amount of the fuel mixture increases, which must be ignited when the chainsaw is started. In this case, to start the engine, it is necessary to increase the number of jerks of the starter cord. To accelerate the return of the drum mechanism, manufacturers use a special steel recoil starter spring with excellent elasticity. To facilitate the launch of the chainsaw, leading brands use other methods:

  • Pre-enrichment of the fuel mixture with a separate shutter;
  • Installation of an automatic decompression valve, which provides a decrease in pressure inside the cylinder of the chainsaw;
  • Installation of a primer designed for pumping fuel before starting the engine.

The use of one of these technologies greatly facilitates the launch and extends the life of the starter, which is especially noticeable at low temperatures.

Typical breaks and repair of a chainsaw starter

The appearance of various malfunctions of the starter leads to the inability to start a chainsaw. The most common starter breakdowns include:

  • The starter pulley has completely burst, or cracks have appeared on it;
  • The spring burst;
  • The starter cable broke.

Do-it-yourself tools will be required to fix each of these malfunctions. You must have a set of screwdrivers and a spare cable with you. Remove and inspect the starter for the chainsaw in the following order:

  1. To find the cause of the breakdown, the starter from the chainsaw will need to be removed. To do this, unscrew the screws with which the protective cover is held with the starter attached to it;
  2. After removing the cover, you must carefully unscrew the screw through which the starter is attached to the protective cover;
  3. Then you need to try to smoothly start the starter. for this, remove the spring and clips from it;
  4. Further, a coil with a cable is removed from the starter for inspection.

As a result of inspection, you can find a number of typical malfunctions. These include:

  • Various pulley damage in the form of tears or cracks mainly in the rear of the part. they interfere with the normal operation of the entire starter;
  • Damage to the starter spring of a light start. in such cases, not only the spring itself can be faulty, but also the place of its fixation. this is the most vulnerable part of the spring;
  • The starter flywheel dog is damaged.

In any case, any defective part must be completely replaced with a new spare part.

How to replace the chainsaw starter spring?

In order to replace the old spring in the disassembled starter, proceed in the following order:

  1. Before installing the chainsaw starter spring, you will need to remove the clip of the mechanism. this should be done very carefully so as not to break the part;
  2. Then you need to look inside the cage. in it you will see a spring wrapped around a C-shaped element. To pull out the spring, fix the upper part with your finger and slightly pull the starter handle to the side;
  3. After removing the old spring, wrap a new part. At the same time, try to avoid kinks and twisting of the new spring element;
  4. To assemble the spring of the starter of the chainsaw, you will need to act as carefully as possible, otherwise one incorrect movement can lead to unwinding of the spare part;
  5. After you have managed to fully insert the spring into the starter, you must carefully lock the clip.

At the last stage, it remains only to assemble the chainsaw starter and try to start the tool. It is possible that you will have to make 10 to 20 jerks. this is necessary in order for the spring to finally fall into place.
