Studs

Check that the stud bolts have not worked loose
from their seat in the crankcase.
Check the depth of stud bolt driving with a gauge,
as indicated in the picture. If it varies significantly
from the driving depth indicated, it means that the
stud bolt has yielded.
In this case, replace it.
By working on two fitted cylinder head fixing nuts,
nut and lock nut, as shown in the picture, remove
the stud bolt from its seat.
Clean the threaded seat on the carter thoroughly.
Refit a new stud bolt and apply the special product
on the threading crankcase side.
Tighten up to the depth of the driving indicated.
