LOWER CRANKCASE PREPARATION
NOTE
Always replace plain bearings when the crankcase or
connecting rods have been disassembled. Refer to
bearing selection procedures.
1. Remove all traces of crankcase sealant from the
crankcase mating surfaces. Inspect the surfaces
closely for nicks, burrs or damage.
2. Clean bolt hole threads to remove any oil or
crankcase sealant.
3. Inspect crankcase bearing bores. Replace the
crankcase assembly if a bearing bore is galled or if
bearing inserts have rotated in the case.
4. Be sure alignment pins are in place where used.
5. Refer to “Oil Flow Chart” at the beginning of this
chapter and trace the oil paths through the
crankcase and cylinder.
6. Flush all oil passages with solvent and then warm
soapy water. Rinse with clear, warm water and dry
with compressed air.
7. Be sure passages are clean and dry before
assembling the crankcase.
