(4) Checking the side gap of a crankshaft
After assembling the crankshaft, tighten the main
bearing cap to the specified toque, and move the
crankshaft to one side, placing a dial gauge on one end
of the shaft to measure thrust clearance.
Replace the thrust bearing if it is worn beyond the limit.
Other measurement method can also be effective.
Insert the thickness gauge directly into the clearance
between the thrust metal and crankshaft thrust face.
