(a) Inspect for circle runout. (1) Place the crankshaft on V-blocks. (2) Using a dial indicator, measure the circle runout at the center journal. Maximum circle runout: 0.06 mm (0.00236 in.) If the circle runout is more than the maximum, replace the crankshaft. (b) Inspect the main journals. Standard journal diameter: 66.988 to 67.000 mm (2.6373 to 2.6378 in.) If the diameter is not as specified, check the oil clearance. If necessary, replace the crankshaft. (2) Check each main journal for taper and out-of-round as shown in the illustration. Maximum taper and out-of-round: 0.02 mm (0.000787 in.) If the taper and out-of-round is more than the maximum, replace the crankshaft. (c) Inspect the crank pins. Standard crank pin diameter: 55.982 to 56.000 mm (2.2040 to 2.2047 in.) If the diameter is not as specified, check the oil clearance. If necessary, replace the crankshaft. (2) Check each crank pin for taper and out-of-round as shown in the illustration. Maximum taper and out-of-round: 0.02 mm (0.000787 in.) If the taper and out-of-round is more than the maximum, replace the crankshaft. 10. INSPECT CRANKSHAFT OIL CLEARANCE (a) Clean each main journal and bearing.
