Intake and Exhaust Cam Height
1. Measure the height of the cam at its highest point with an
outside micrometer.
2. If the measurement is less than the allowable limit, replace the
camshaft.
Oil Clearance between Crank Pin and Bearing
1. Measure the crank Pin O.D. and the connecting rod big end
bore after tighten the connecting rod screws to the specified
torque with a micrometer, and calculate the clearance.
2. If the clearance exceeds the allowable limit, replace the
bearing.
(Reference)
A
When the crank pin wears further over a long period of use and
oil clearance exceeds the allowable limit after replacing the
standard bearing, use a undersize bearing. Machine the crank
pin according to the precautions.
