Cleaning and inspection
NOTE!
If the bearings are mounted in the crankcase,
exercise care to avoid dirt and foreign partic-
les getting in.
Clean all parts and scrape of the remains of gasket material
from the mating surfaces of the crankcase halves.
Check the following:
1. That the big-end bearing does not have any radial
play. Axial play is acceptable.
2. That the big-end bearing does not have any score
marks or is discoloured on the sides. See fig. 7.
3. That the bearing surfaces for the little-end do not
have any score marks or are discoloured. See fig. 8.
4. That the crankshaft main bearings do not have any
play or dissonance.
5. That the surfaces of the seals to the crankshaft are
not worn and that the rubber has not hardened.
6. That the crankcase has no cracks.
