Crankshaft and Connecting Rods
•
Measure the connecting rod big end inside diameter, and
mark each connecting rod big end in accordance with the
inside diameter.
•
Tighten the connecting rod big end nuts to the specified
torque (see Connecting Rod Installation).
NOTE
○
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
clearance.
If the clearance exceeds the service limit, replace the
crankcase halves as a set.
NOTE
○
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
Standard: 0.09
∼ 0.19 mm (0.0035 ∼ 0.0075 in.)
Service Limit: 0.39 mm (0.0154 in.)
