Upper 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 sealer 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 upper crankcase.
Piston Ring Installation
NOTE: Apply clean engine oil to all ring surfaces
and ring lands upon installation. Always check
piston ring installed gap before rings are installed on
piston (see Chapter 3 – Piston Ring Installed Gap,
page 3.58. Clean accumulated carbon from piston
ring grooves and oil ring lube holes if piston has
been in service.
