If the bearings are fitted to the crankcase,
take care to prevent any dirt and foreign
particles from entering.
Clean all parts and scrape off all gasket remains
from the contact surfaces on the crankcase halves.
Check the following:

That the big-end bearing does not have any
radial play. Axial play is permitted. See figures

That the big-end bearing does not have any
score marks or is discoloured on the sides.
3.

bearing does not have any score marks or is
discoloured. See figure 70.
