Crankshaft and Connecting Rods
Measure the connecting rod big end inside diameter, and
mark each connecting rod big end in accordance with the
Tighten the connecting rod big end nuts to the specified
torque (see Connecting Rod Installation).
The mark already on the big end should almost coincide
with the measurement.

Install the new inserts in the connecting rod and check
insert/crankpin clearance with the plastigage.
Crankshaft Side Clearance Inspection
Insert a thickness gauge [A] between the crankcase main
bearing and the crank web at the #3 journal to determine
If the clearance exceeds the service limit, replace the
crankcase halves as a set.
The upper and lower crankcase halves are machined
at the factory in the assembled state, so the crankcase
halves must be replaced as a set.
Crankshaft Side Clearance
