Bushings
Check that the bushing in the small end has not come
loose and shows no sign of scoring or seizure. If this
is not so, change it.
Disassembly and assembly are performed with a
suitable drift.
When driving in, make sure that the oilways in the
bushing and small end coincide. Using a boring
machine, regrind the bushing to obtain the
prescribed diameter.
