Removing and disassembling the engine

The engine is held in place by 4 screws installed on the bottom of the Stihl 180 chainsaw. To remove, unscrew them, then carefully remove the engine from the seat and the rubber pipe of the carburetor.

To disassemble the engine, 4 crankcase screws are unscrewed, and it is removed, then you can remove the crankshaft assembly with oil seals, bearings and piston rings.

To remove the piston from the connecting rod, you will need to remove the locking ring from the seat using a thin screwdriver, then the piston pin is squeezed out from the opposite side, after which the piston is retracted to the side.

Carburetor, muffler and ignition coil

To remove the carburetor, it is necessary to have a head 8 and an extension, with which it is convenient to unscrew the nuts securing the carburetor and air filter. Before dismantling the carburetor, it is necessary to disconnect the ignition wire and the choke rod from the engine control lever and remove the lever, only then the air filter and carburetor are removed.

With a high head 19, it is necessary to unscrew the clutch. The thread on it is left-handed, so it unscrews towards the tire, and not the back of the Stihl 180 saw.

Having untwisted and removed the clutch, you need to immediately remove the reflective plate and the oil pump drive, this is easy to do, because they are put on the shaft without any fastening.

Removing the flywheel

The flywheel of the Stihl 180 chainsaw is twisted with great effort, so a head with a metal knob is required to remove it. The nut holding the flywheel is unscrewed by the head by 13.

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

After the piston is locked in the cylinder, you can unscrew the flywheel nut. The thread in the nut is ordinary, so you need to turn it to the left. Having loosened the nut, it is not necessary to remove it to the end, it is enough to unscrew it until its upper edge is equal to the tip of the shaft, after which a soft metal drift is installed on the nut and a sharp blow is made on it. Thus, the flywheel from a sharp impact jumps off the shaft and can be easily removed without the help of additional tools.
