Clutch drum
Remove needle bearing
The needle bearing is pressed into
place most easily using a vice.
Place an object measuring 14.5 mm
in diameter against the bearing. The
hexagonal head of an M8 bolt is a
perfect fit. Support the inside of the
drum with a socket, about 21 mm.
Press out the bearing using a vice.

Fit needle bearing
Make a simple tool for fitting the
needle bearing. Use a short bolt,
M10, with its nut, and at the very
end place a washer that has a larger
outer diameter than the bearing. A
few turns of tape over the bolt’s
thread will protect the bearing from
damage and will centre it.
Fit the bearing using the vice as in
the picture. Press in the bearing so it
is flush with the clutch drum – the
washer will ensure that it is pressed
in to the correct level.
Lubricate the bearing with a few
drops of oil before refitting the drum
on the crankshaft.
