Assembly
!
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 fitting 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 continuing
work.
NOTE!
Exercise care so that dirt and foreign
particles do not get into the bearing.
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.
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.
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.
