7.28 Repairing damaged threads

A repair kit, 503 27 33-01, is available for repairing
damaged threads.
First drill out the hole using:
6,1 mm drill bit for plastic crankcase
Then screw in the thread insert using a suitable
bolt and spanner.
This type of thread insert is best suited for use
in plastic and magnesium, but not for repairing
threads in aluminium. In that case use a helicoil
insert with metric screw.
