crankcase. Match each rod cap with its corresponding
connecting rod. (Photo U)
NOTE: The connecting rod caps are “cracked” dur-
ing manufacture creating a unique mating surface
between the connecting rod and cap. Always verify
that the lower cap matches the connecting rod.
35. Always keep the connecting rod plain bearings, rod
caps, and bolts with the piston assembly the engine
was manufactured with.
36. Remove the crankshaft assembly from the crankcase.
Remove each crankshaft plain bearing from both
crankcase halves and place with its original crankshaft
journal.
NOTE: Always mark the bearings for identification
during assembly and oil clearance measuring proce-
dures.
