Check the engine crankshaft damage of Main Journal and Crankpin and
channels of lubricants, if defective / broken crankshaft must be
repaired or replaced.
Check for wear, damage and cracks of crankgear. If defective, crankshaft crankgear parts repaired or replaced.
Check the surface of the front / rear crankshaft oil seal related. When damaged to be repaired or replace his collar.

Check the surface of the front / rear crankshaft oil seal related. When damaged to be repaired or replace his collar.
Check, Measure and record the out side diameter of main journal. When
the measurement has reached the limit balk repair roundness or
cylindricity, then the crankshaft should be improved (made undersize)
and attach the appropriate oversize main bearing. When the out side diameter reaches Wear Limit (limit wear and tear) replace the crankshaft.
Even if the measurement results out side the main journal diameter repair has not reached the limit, but if roundness has reached the limit then the crankshaft should be undersize.
Check, Measure and record the diameter Crank Out Side Pin. When the out side diameter has been achieving the repair limit or if the roundness / taper exceeds the limit crankpin repair must be done undersize. When the out side of the crankpin diameter smaller than the wear limit of the crankshaft must be replaced.
Check and calculate the clearance between:
A. Out side the main journal diameter and inner main bearing (bore) diameter.
B. Out side diameter crankpin and the bearing inner diameter.
Measure Crankshaft Bending (crookedness crankshaft) in the following manner:
A. End play in the measure before the crankshaft is removed from the block and after mounted on the block, when assembling (connecting rod is not installed).
B. Measurement before the crankshaft end play off of the block is as a guide when reassembling.
