7.28 Repairing damaged threads
If threads on the chainsaw are worn, the repa-
ration kit, 503 27 33-01, is available.
First drill with:
6.1 mm drill for the magnesium crankcase
Then screw in the thread plug using a suitable
screw and wrench.
This type of screw plug is ideal for plastic
and magnesium but cannot be used to repair
threads in aluminium. There is another type of
thread plug and metric screw available for this
purpose. See gure 84. Check the manufac-
turer’s manual for thread information.
