Crankshaft: Testing and Inspection
INSPECTION
1. Inspect crankshaft for runout.
(a)
Place the crankshaft on V-blocks.
(b) Using a dial indicator, measure the circle runout at the center journal.
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:
STD: 54.988 - 55.003 mm (2.1653 - 2.1655 inch)
U/S 0.25: 54.745 - 54.755 mm (2.1553 - 2.1557 inch)
Crank pin diameter:
STD: 51.985 - 52.000 mm (2.0466 - 2.0472 inch)
U/S 0.25: 51.745 - 51.755 mm (2.0372 - 2.0376 inch)
If the diameter is not as specified, check the oil clearance. See: Service and Repair
If necessary, grind or 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.
3. If necessary, grind and hone main journals and/or crank pins.
Grind and hone the main journals and/or crank pins to the finished undersized diameter (See procedure in step 2).
Install new main journal and/or crankshaft pin undersized bearings.
