INSPECTION AND REPAIR OF CRANKSHAFT
1. MEASURE CRANKSHAFT
(a) Place the crankshaft on V-blocks.
(b) Using a dial gauge, measure the circle runout at the center journal.
Maximum circle runout: 0.06 mm (0.0024 in.)
If the runout is greater than maximum, replace the crankshaft.
2. INSPECT MAIN JOURNALS AND CRANK PINS
(a) Using a micrometer, measure the diameter of the main journal and crank pin.
Main journal diameter: 63.985 - 64.000 mm (2.5190 - 2.5197 in.)
Crank pin diameter: 54.987 - 55.000 mm (2.1648 - 2.1654 in.)
If journals are worn, regrind or replace the crankshaft.
(b) Measure the journals for out-of-round and taper as shown.
Maximum taper: 0.02 mm (0.0008 in.)
Maximum out-of-round: 0.02 mm (0.0008 in.)
If taper and out-of-round are greater than maximum, regrind and/or replace the crankshaft.
