Crankcase sides MS and CS are attached with
six screws 1.
Two pins 2 ensure proper fitting.
When assembling the ball bearings, note the
following:
•
Press one ball bearing onto the clutch side
of the crankshaft. Press the bearing onto the
shaft using an assembly sleeve, pressing
only on the inner bearing ring. Place a
wedge between the crank webs.
•
Heat the clutch side of the crankcase to
150-160 ° C using a hot-air blower or in an
oven. Evenly apply Loctite 620 to the outer
ring of the bearing (on the crankshaft), and
insert into the heated housing without further
pressure.
Note: Before applying the Loctite 620,
degrease both bearings.
•
Heat the magneto side of the crankcase to
150-160 ° C using a hot-air blower or in an
oven. Evenly apply Loctite 620 to the
bearings, and insert into the heated housing
without further pressure.
• Reattach the crankcase sides. Place a
wedge between the crank webs when
pressing.
Always use a new gasket. After bolting the
crankcase sides together, cut off the flash 3.
