How to remove the clutch from a STIHL 180 chain saw

Learn how to remove the clutch on a chainsaw with examples from leading brands like STIHL, Husqvarna and Partner

Repairs to any machine must start with preparatory work, and the STIHL 180 is no exception. The STIHL 180 chain saw requires the removal of the side cover, the chain and the guide bar before it can be disassembled. Next, using a compressor and a brush, it is necessary to clean the chainsaw from dirt, sawdust, oil stains and other things.

When cleaning the saw, special attention should be paid to the place where the chain saw’s drive sprocket is located, i.e. к. this is the most contaminated area.

Where there is a lot of oil, you can wash it off with clean gasoline.

When to remove the clutch

Disassembly of the clutch in order to remove it is carried out in such cases:

  • When the spring is broken (the chain turns, the engine runs intermittently);
  • the spring is gone;
  • a piece of the drum has broken off (in this case you will hear a noise, the chain of the chainsaw will also rotate);
  • temporary wear and tear (it’s time to remove and replace the clutch because it has used up its life).

Modern chainsaws run on two-stroke engines, which are connected by a reducer to the saw chain. The chain moves along the bar and, according to the centrifugal principle, should stay stationary at idle speed, i.e. be safe for the person holding the chainsaw.

If the load on the tool exceeds the recommended load, the clutch will loosen or completely stop transmitting torque to the bar. This will cause the engine to stop. When these situations occur, the clutch wears out, so it needs to be replaced over time. Some chainsaw manufacturers’ manuals say that the clutch is an expendable part, which means that it has to be replaced from time to time.

Disassembling chainsaw clutch

In this review, we will learn how to remove and replace the clutch on a chainsaw yourself, when to do it and what tools you may need.

Replacing the clutch

When replacing the clutch, we do not recommend using metal or plastic objects as a stopper. The former can scratch the cylinder, the latter can litter it.

  • Engage the chain stop brake, remove the protective cap, and remove the saw headset;
  • Remove dirt, sawdust, dried grease, if any;
  • Remove the air filter and spark plug;
  • Using a spark plug wrench, unscrew the spark plug;
  • Rotating the crankshaft, bring the piston to the upper point, then withdraw it by 6-9 mm;
  • With a rope, 7-8 mm in diameter, stop the piston in the upper position;
  • Unscrew the nut on the clutch with a wrench.

Most chainsaw moving parts, have right-hand rotation. That’s why the nut on the clutch has a left-hand thread. Remove the cover by turning the spanner clockwise. Do not perform this operation with a hammer and chisel. you will break the edges!

  • Remove the cover and drive sprocket. We diagnose malfunctions and estimate the wear of parts. Evaluate the condition of the needle bearing;
  • If necessary replace parts with new ones (the drive sprocket needs it most often);

Mounting the chainsaw clutch system is done in reverse order, but you should pay attention to some peculiarities.

Installation of clutch system nuances:

  • On some chainsaw models there may be a washer between the drive sprocket and the clutch. Note which end of the sprocket faces the engine;
  • Some oil pump drives are equipped with a special spring (washer), which is responsible for transmitting the rotary motion from the drive sprocket to the oil pump. it is important to adjust the spring so it fits the free end (whisker) into the proper slot on the sprocket housing. Otherwise, the saw headset will not lubricate;

Important: Always check the automatic oil feed system after disassembling and reassembling the clutch.

  • Then you can proceed to removing the clutch itself. To do this with the tool provided in the saw kit or with a wrench for maintenance of an angle grinder, the clutch must be carefully unscrewed in the direction of the clock hand. It is important not to tear the mechanism from the threads;
  • Next you have to dismantle the drum and the drive sprocket;
  • The next step is to install a new clutch and screw it on the thread against the clock hand up to the stop. To do this, you need to lock the crankshaft again. Otherwise there is a risk of breaking the starter, located on the opposite end of the crankshaft;

Handwheel removal

The flywheel chain saw STIHL 180 is screwed with a lot of force, so to remove it you will need a head with a metal screwdriver. The nut that holds the flywheel is unscrewed with a 13 head.

To block the crankshaft from turning, you need to unscrew the plug and through the spark plug hole install a piston stopper, if it is not available, you can use an old starter cord, with knots tied to it and immersed in the cylinder through the spark plug hole.

categorically forbidden to keep the flywheel from turning by installing between his ribs and the body of the power screwdriver and other tools, with this method of blocking against rotation, the flywheel blades are not able to withstand the load and break.

After the piston is locked in the cylinder, the flywheel nut can be unscrewed. The thread in the nut is common, so turn it to the left side. After loosening the nut there is no need to remove it completely, it is enough to unscrew it until its upper edge is level with the tip of the shaft, and then set the soft metal hammer on the nut and make a sharp blow on it.

Each saw model has its own specifics in carrying out this procedure. That’s why let’s describe this process from a general idea point of view.

The chain brake cover must be removed. Pull the brake lever toward you to begin. This is to ensure that the brake lining does not touch the clutch cup. Then loosen the two nuts holding the cover. Loosen the mechanical chain tensioner. Release the tension in the chain and guide bar. Then loosen the two nuts and remove the chain brake cover.

Remove the bar and chain and remove any debris if any.

Remove the spark plug from the spark plug hole in the cylinder.

Next, secure the piston in the cylinder. To do this, rotate the clutch, watch the piston move upwards. In most cases, once the piston overlaps the exhaust port, drop any suitable rope into the spark plug hole in an amount sufficient to prevent the piston from moving further up. It is possible to strengthen the effect on the rope to tie simple knots. Remember that the rope has to be pulled back later. So don’t miss the other end
