Crankshaft: Testing and Inspection

1. Inspect crankshaft for circle runout.
(a) Place the crankshaft on V-blocks.
(b) Using a dial indicator, measure the circle runout, as shown in the illustration.
Maximum circle runout: 0.06 mm (0.0024 inch)
If the circle runout is greater than maximum, replace the crankshaft.





2. Inspect main journals and crank pins.
(a) Using a micrometer, measure the diameter of each main journal and crank pin.
Main journal diameter: 60.988 - 61.000 mm (2.4011 - 2.4016 inch)
Crank pin diameter: 52.992 - 53.000 mm (2.0862 - 2.0866 inch)
If the diameter is not as specified, check the oil clearance.

If necessary, replace the crankshaft.
(b) Check each main journal and crank pin for taper and out-of-round as shown.
Maximum taper and out-of-round: 0.02 mm (0.0008 inch)
If the taper and out-of-round is greater than maximum, replace the crankshaft.
