That is, make the choice for you.

The next small aspect regarding the choice to repair without the help of others or not, is that for the diagnosis of the chainsaw and its forthcoming disassembly and repair, you need to have some special tools and certain knowledge of the design of the saw. Otherwise, you cannot even unscrew and remove the flywheel without damaging it here.

Carrying out repairs on their own, the saws quite often break off duralumin fan blades located on the flywheel. This happens because during disassembly they do not use a special crankshaft stopper, but try to fix it by installing a screwdriver between the saw body and the flywheel blades, which leads to sad consequences. The flywheel nut has a severe tightening torque, and the fragile blades are not able to withstand such a force.

Stihl 180 Repair Tools

To carry out relatively high-quality repairs Stihl chainsaws ms 180 without the help of others, you will need to have:

  2. Lack of thread on the oil pump worm gear;
  3. Blockage or malfunction of the pump itself;
  4. Depressurization of the oil system (there will be oil smudges on the bottom of the chainsaw).

To check the thread on the worm drive of the oil pump, you will need to remove the drive sprocket of the chainsaw and untwist the clutch. To do this, the spark plug is screwed out and a piston stop is installed in its place, thereby ensuring reliable fixation of the crankshaft of the tool from turning.
