See illustrated parts list for correct
installed sequence and positions of
crankcase components.

pump.

crankcase. Insert and tighten
down the mounting screws.
– Before heating the crankcase,
remove all rubber and polymer
034, 036, 036 QS
components, such as oil suction
and delivery hoses, grommets,
annular buffers and levers -
8.1 and 11.4.
– Inspect condition of all parts and
replace as necessary.
– Heat area of bearing seat on
clutch side of crankcase to
approx. 120°C.
Place ball bearing in position and
press it in until it locates against
the oil pump.
Note:
The ball bearing can be fitted by
hand if the crankcase is heated as
specified. This operation must be
carried out very quickly because the
bearing absorbs heat immediately
and begins to expand.
– Remove the oil pump and refit the
plastic plug.

its tab locates in the bottom right
recess.
