Crankshaft
Inspection
. Clean the crankshaft oil passages with pipe cleaners
or a suitable brush.
. Check the keyway and threads.
Alignment
. Measure runout on all main journals to make
sure the crank is not bent.
. The difference between measurements on eachjournal must not be more than the service limit.

Pistons
Inspection
1.Check the piston for distortion or cracks,
NOTE: lf a cylinder is bored. an oversized piston
must be used.
Measure the piston diameter at a distance A from
bottom of the skirt.
