Crankshaft: Testing and Inspection
1. Inspect crankshaft for runout. Place the crankshaft on V-blocks. Using a dial indicator, measure the circle runout at the center journal. Maximum
circle runout: 0.03 mm (0.0012 inch). If the circle runout is greater than maximum, replace the crankshaft.
2. Inspect main journals and crank pins. Using a micrometer, measure the diameter of each main journal and crank pin. If the diameter is not as
specified, check the oil clearance. If necessary, grind or replace the crankshaft.
