Unscrew the nut until it is level with the shaft. Then use a punch and a hammer. One sharp movement (stroke) is necessary in order to safely remove the flywheel.

The flywheel bounces off the shaft, after which it is removed manually, without the use of special tools.

Puzzling themselves over how to disassemble a Stihl chainsaw, many forget about the standard cheat sheet, with which the procedure will take a minimum of time.

  1. At the preparation stage, remove all covers, including the side, tire, chain. We carry out cleaning with a compressor, use a brush, if necessary, to get rid of oil drips and dirt. Carefully process the sprocket, the most contaminated part of the tool. Pure gasoline is sometimes used to remove excess oil.
  2. Remove the handle, which is connected to the body with three rubber shock absorbers. To remove them, first remove the plugs from the plastic in the internal cavity with a screwdriver. The upper shock absorber may be the most durable, so sometimes use a powerful screwdriver. Unscrew a couple of screws to remove the wire rod.
  3. Remove the starter. As soon as the top cover is removed, remove the starter screws, and then dismantle the fuel tank and oil tank covers. This step is simple, taking a minimum of time.
  4. We remove the flywheel, which is fixed most securely. Follow the recommendations of professionals, and in no case do not fix the flywheel, trying to avoid turning it (otherwise it can be damaged, since its blades can not cope with a lot of pressure).
  5. We remove the oil pump (its drive) and clutch. Before you get to this stage, do not forget to remove the star (the lead is removed). This can be done by removing the lock washer from the shaft groove. With an asterisk, remove the needle bearing. After that, using the head on 19, we unscrew (left, in the direction of the tire) the clutch. By following this step exactly according to the instructions, you can easily remove the oil pump drive and the reflection plate, which are not connected to the shaft fasteners.
  6. We dismantle the ignition coil together with a muffler and a carburetor. The main assistant will be the head at 8 (also can not do without an extension cord). It will not take a lot of time to unwind the fasteners of the air filters and the carburetor. Do not forget to eliminate the ignition system drive along with the air damper and its draft. These elements must be disconnected from the lever on the engine. The silencer is removed in one motion after two nuts have been removed. The ignition coil is fixed by the same principle.
  7. Engine dismantling. As standard, 4 screws are used to fasten the engine, which are located in the bottom of the working tool. To carry out the dismantling accurately, the engine is taken out of the seat (there is also a pipe made of rubber here). After you remove the screws, remove the stuffing box with the crankshaft, piston rings and bearings. No special tools are needed for this. However, sometimes a puller is necessary (in the case where the bearings are bluntly pressed onto the shaft).
