18.3 Assembly
To install the crankcase and crankshaft:
1. If bearings are to be fitted:
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 the crankcase half of the clutch side the
bearing should be fitted flush with the inside of the
crankcase (B). See fig. 9.
C. Allow the crankcase half to cool before continuing
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 (Refer to pos. 20 "3 Service tools" on
page 8). 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 crank-
case and crankshaft are reassembled.
NOTE! The crankshaft should be fitted in the
crankcase half of the clutch side first.
3. Use tool (Refer to "3 Service tools" on page 8,
Pos. 20) and pull the crankshaft into the crankcase
half of the clutch side. See fig. 11. Pull until the
crankcase shoulder mates with the bearing.
