How to insert a spring into the grass trimmer starter

Gasoline grass trimmer starter repair may be needed at the most inopportune time. In this case, the problem can be solved in two ways: to replace the broken part or replace the entire unit. The latter option will cost more. To repair the device with your own hands in most cases you will need only a screwdriver with the appropriate tip from the tools. 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 assembly-disassembly of the starter on the trimmer to achieve the desired positive result.

How to Fill the Spring in the Grass Trimmer Starter

Gasoline grass trimmer starter repair may be needed at the most inopportune moment. You can solve the problem in two ways: replace a broken part or modify the entire assembly. The latter option will cost more. To repair the device yourself, in most cases you only need a screwdriver with the appropriate tool tip. Repair work does not require much time and no special knowledge. It is enough to know the design, principle of work, nuances of assembly and disassembly of the starter on the trimmer to achieve the desired positive result.

Design and principle of the starter on the trimmer

Gas motor. it is basically the main part of the car. Its power lies in the range of 0.5-2.5 liters.с. The movement from it is transferred to the shaft, which is located inside the hollow rod, and then through the reducer, consisting of gears, already a line or a knife (working body).

  • protective guard;
  • lever;
  • A belt for easy use of the machine;
  • The starter, which serves to start the internal combustion gasoline engine.

All motorcycle parts are shown in the photo below. Briggs 3.5HP Recoiling a Starter Spring

The starter on the grass trimmer tab is an integral part that starts the engine. It is shown separately in the two photos below.

Starter mechanisms of different models of gasoline tanks work on the same principle: during the start of the engine, the tabs, marked in the photo above, with the number 1, enter the hook with the pawls 3. When the motor begins to work, they return to their previous position because of the centrifugal force. The wires play a similar role 2.

The process of resetting the elements of the mechanism is due to the presence of a spring winding around the axis. It unfolds when the rope is pulled out. After releasing the cord, it retracts and tightens because of the winding spring. When starting an internal combustion engine, the starter rotates its shaft until it begins to run (it starts).

To date, motorcycles with a gasoline engine starter mechanisms of two types:

The first variant is much more common.

The starter to work without breaking for a long time. It is not possible to state unambiguously the period of no-failure operation. Everything is determined by the initial quality of the device and compliance with the rules of its processing.

The main malfunctions of the grass starter trimmer

It is not difficult to determine the cause of a trigger failure. There are several basic options:

The above information is shown in the photo below.

It may happen that the mechanism of the starter will be accidentally broken. The consequences will be unfortunate if the broken rope is wound around the engine flywheel: the spring will burst, the pulley will come off. But such cases, when you need to completely replace the starter assembly, are very rare. In most cases, all you have to do to fix the mechanism is put in a new spring or replace the cord.

Removing and dismantling the starter, replacing broken parts

To repair the grass trimmer starter, you first need to disassemble it, and then reassemble. The process is not particularly difficult. You will need to work a screwdriver with the desired tip shape.

Doing everything carefully, observing safety procedures, chiefly that the spring in case of accidental flight does not damage the master.

Analyze the starter assembly

Disassemble the trigger mechanism to install new parts to replace the broken parts in the following sequence:

  • Unscrew the screw that locks the pulley with the starter cover with a screwdriver;
  • remove the spring and antennae;
  • carefully remove the pulley (you must turn your head at the same time or work wearing goggles and gloves);
  • Determine why the trigger mechanism is broken;
  • if the spring is almost completely destroyed, it is replaced;
  • when the spring leaves the hook, it is placed in its original place by bending the antennae in front of it (photos show the stacking process);
  • After the spring plate is inserted in the slot, carefully twist it.

To change the spring, you need to work carefully and carefully: it can accidentally break through under the force caused by installing it in place. Even if you carefully remove the roller, the spring strip flies out of the coil very quickly and can injure your hand with its sharp edges.

It is not always possible to put the spring plate back on immediately. It often slips, so attempts must be repeated until the desired result is achieved.

starting assembly

The starter assembly is assembled in several steps:

  • the coil is inverted by installing it in such a way that the spring bend fits exactly into the slot of the housing, as in the photo below;
  • lay two washers with a spring between them;
  • put the cup with the antennas in place;
  • tighten the screw (picture below).

When performing the above manipulation, two washers must be put in place. If this is not done, the spring will eventually damage the plastic cup, and when it is raised, it will begin to jam. It makes it feel as if the spring has flown. To eliminate this disadvantage, you need to install this part of a longer length or an additional washer.

When such spare parts are not available, you can unscrew the screw slightly and the starter assembly will start without jamming. But this option is only temporary. it is better to have it repaired as soon as possible.

Spring tension

After installing the spring, you have to tighten it. To do this, carry out the following steps:

  • remove the starter cord from the handle;
  • then insert the rope into the groove of the spool;
  • stretch the springs by turning the spool in the counterclockwise direction (see the manual for the grass trimmer model used).);
  • specify the required number of revolutions specified in the operating instructions for the grass trimmer model used, and correspond to the length of the cord used;
  • at the very end the rope is screwed into the hole provided in the starter cover;
  • put the knob in place, securing it with the knot.

If the spring continues to fly after repair, you can get rid of it as follows:

  • insert a suitable piece of plate part into the groove at the location of the spring hook;
  • Drill a slot in the coil holes on either side of the hole in which to insert the spring hook, and secure it with wire.

Replacing a torn cord

Torn rope is replaced in the following sequence:

  • old cord removed;
  • Choose the appropriate size of rope (thickness and length);
  • passing through a special hole located in the spool, tie a knot;
  • Raven spring, producing the required number of revolutions;
  • fasten the handle.

It is best to stretch the spring plate with your partner so that the edge of the cord does not roll up inside the starter mechanism.

It is not difficult to assemble the starter on the trimmer and wind the spring, just need to do it carefully and cautiously. The starting mechanisms are the same for different models of gasoline break, so they are repaired in the same way. There are some nuances due to their design features.

But now we will consider a more common case, when the breakage is not so serious, and show how to repair the starter with your own hands, if the cord breaks without any destructive effects, or unwinds because the internal spring just fell and does not work. At least first, the desire to believe it. But to find out if this is true, you need to disassemble the starter.

How to repair the gasoline starter with your own hands?

If the starter cord breaks, everything is clear: we take out the old rope, take the appropriate length and thickness (you can use linen), pass it through the hole in the spool, tie a knot. Next, we press the spring for the required number of turns, only then do we fix the handle. and voila! Details of how to do this are given below.

But what if everything is okay with the rope and the starter coil (pulley) does not roll? Let’s look at this problem step by step on the example of the ADA GroundDrill gasoline-powered drill, which has a pulley with two metal antennas for 2 hooks.

As for other types of manual starters of this design, which are widely used in gasoline trimmers, trimmers and power drills, the whole process of repairing the starter will look similar, with a few nuances.

Repairing the starter: disassembling

Loosen the screw that fastens the pulley to the starter cover. Remove the antennae, spring. The pulley itself is gently pulled so that the spring doesn’t bounce in the face. Even with the most precise disassembly, it usually flies right out of the spool and abruptly turns into a long metal strip or twists into rings.

If the spring breaks or one of its hooks and hooks breaks, it is impossible to repair the starter simply and quickly. Need to replace the spring. To avoid spending the money to buy a new starter, you can only look for them on sale.

If the starter spring just broke, t. Е. One of the hooks is not fixed, just insert it if necessary, tightening the hooks a little tighter (just do not break it!) Insert the spring from the outer hook into the pulley slot and start twisting it with your fingers inside the coil. and not letting it pop out.

Getting the starter spring on for the first time may not seem so easy, but everything has experience. With a little practice, you can easily wind the spring around the pulley for no more than a minute.

Motorcycle starter repair, grass trimmer

The winding of the starter spring is carried out. It remains only to reassemble the starter and turn the spring to the desired value.

How to assemble the starter?

The most important thing in the process of self-repairing the starter. how to assemble it correctly.

After the spring is fully wound, you must carefully rotate the coil and insert it into the starter housing, so that the second spring hook falls into the slot of the housing.

Installing the pulley (black in this photo), we scan the hole in it so that the spring hook fits into the slot on the starter cover.

Then, if there is a spring under the screw, first install it, remembering to place washers on the bottom and top of the spring.

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

Then make sure that the washer located on the spring does not fall out. Why it’s important? The point is that the spring scratches the plastic cup with its end, as a result of which the latter wears out and begins to tighten the screw to the coil more tightly. Insert and retighten the spring. spring about you rooster spring. For this reason, the situation is very similar to a spring break: the handle pulls out of the starter, but does not turn back. However, when the starter screw is unscrewed, this problem disappears. Such a malfunction of the starter is not easy to fix: just pick up the spring of the same diameter, but a little longer, or install an additional washer. If you tighten the screw a little bit, it will rotate and fly out, which increases the chance of spring break because the pulley will not fit tightly against the starter housing.

They have screwed the coil to the housing, now we need to tighten the spring. Before doing this, it is necessary to remove the starter knob from the rope beforehand. If the knot is too tight, you can simply cut it or try to untie it, such as with pliers. This is so that after you press the spring you can insert the rope into the hole in the starter cover. The other end of the rope must be secured in the spool before it is installed in the body, there is no need to wind the rope around the pulley before tensioning the spring. do it after.

Before the spring comes, estimate how much coil rotation should be wound on the rope. Let’s say the length of the rope on the starter Ada GroundDrill-5 is 5.5 turns around the spool. In this case, make at least 6 turns of the spool in the direction opposite to the winding direction.

So, let’s begin. Without winding, insert the rope into the groove in the specially designed coil. Done, start pulling the spring. To do this, turn the spool counterclockwise. In the direction opposite to the direction of rotation of the spool when winding the rope. It is more convenient to do this not on your knees, but by pressing the starter with one hand to the floor and the other. by turning the spool right behind the rope attached to it. How to repair the starter on a trimmer, do it yourself. How to disassemble and reassemble the starter, tighten the spring and replace the cord. If experience is not enough, the pulley itself can be rotated directly with two hands, but the rope will interfere with it, which may create additional inconvenience. After the required number of turns is done, we pass the end of the rope through the hole in the starter cover, put on the handle, fix it with the knot. It is more convenient to do this with your Rartner so that the end of the cable is not accidentally twisted inside the starter.

By the way, you can make some changes to the design of the starter yourself to secure the end of the spring inside the coil. Then someone has enough imagination. Now I will explain what is needed. It often happens that the spring in these types of starters after the first such self-restoring and installation of the starter on the machine again takes off after a few shocks. the hook is not held in the recess of the coil. This is in spite of the fact that the coil is almost tightly attached to the starter cover and the spring should not hang down freely, much less until the spring is out of engagement. It turns out that when you pull the cable, the spring is pulled, pulled out of the groove. In this case, you can do the following: cut a narrow strip of metal that is thick enough to be inserted into the groove of the coil along with the spring hook. This way, the hook will not hang loosely in the groove, so it will not be easy to break.

A metal plate, tightly inserted into the gap between the spring hook and the walls of the groove, will hold the spring securely.

Another solution to the problem. Drill small holes in the coil on either side of the groove and, after inserting the spring hook, secure it with a thin wire stretched through these holes. But here you need to make sure that this wire doesn’t come into contact when the starter cover rotates from the inside and thus doesn’t brake the pulley. Alternatively, tighten the screw tightly or replace it with a slightly longer length. You can put a gasket between the cover and the coil.

Replacing a torn cord

The torn rope is replaced in this sequence:

  • The old cord is removed;
  • choose a rope of suitable size (thickness and length);
  • After putting it through a special hole, located in the coil, tie a knot;
  • spring is wound up, producing the desired number of revolutions;
  • fix the handle.

It is better to tension the spring plate with a partner so that the edge of the cord does not wind up inside the starter mechanism.

Assemble the starter on the trimmer and wind the spring is not difficult, but you should do it carefully and with care. Breakdowns of starting mechanisms are the same for different models of chain saws, so they are repaired in the same way. In this case, there are some nuances associated with their design features.

Worst case breakage

There are cases where the starter is still functional, but may tear, such as a worn cord. The ratchet has not yet had time to work when you start the engine, and the remains of the cord is immediately reeled on the coil, the return spring loses its hooks, breaks the grooves in the starter housing. Bottom line. replacing both the spring and the housing.

If the lawnmower or grass trimmer model has long been discontinued, it will be difficult to find exactly the same parts, and the starter is replaced as a whole.
