Crankcase and crankshaft
16.1.3 Assembly
Fit the crankcase and crankshaft as follows:
1. If bearings are to be fitted, do as follows:
A Heat the relevant crankcase half to 200°C.
B. Use protective gloves and fit the bearing in the
crankcase side on the flywheel side. When fit-
ting the bearing in clutch side’s crankcase half the
bearing should be fitted flush with the inside of the
crankcase (A). See fig. 9.
C. Allow the crankcase half to cool before continu-
ing work.
D. Fit the rubber stop (A). See fig. 5.
E. Fit the oil filler cap.
2. When fitting new seals the sealing surfaces
should be greased in. When fitting the seal on
the flywheels side use tool 502 50 30-17. The
seal on the clutch side is fitted in the ball
bearing. See fig. 10. The seals can also be fitted
when the crankshaft is in place.
3. Use tool 502 50 30-17 and pull the crankshaft
into the clutch side’s crankcase half. See fig. 11.
Pull until the crankcase shoulder mates with the
bearing.
WARNING!
The crankcase halves are hot and
can cause burn injuries. Wear
protective gloves.
NOTE! Exercise care so that dirt and foreign
particles do not get into the crankcase.
NOTE! Make sure that the connecting rod
does not jam against the crankcase when the
crankcase and crankshaft are reassembled.
NOTE! The crankshaft should be fitted in the
clutch side’s crankcase half first.
