37. INSPECT CRANKSHAFT

(a) Using a dial indicator and V-blocks, measure the

runout as shown in the illustration.
Maximum circle runout:

0.06 mm (0.0024 in.)

If the result is not as specified, replace the
crankshaft.

(b) Using a micrometer, measure the diameter of each

main journal.
Standard Diameter:

71.988 to 72.000 mm (2.8342 to 2.8346 in.)

If the result is not as specified, replace the
crankshaft.

(c) Check each main journal for taper and out-of-

roundness as shown.
Maximum taper and out-of-roundness:

0.02 mm (0.0008 in.)

If the result is not as specified, replace the
crankshaft.

(d) Using a micrometer, measure the diameter of each

crank pin.
Standard diameter:

55.992 to 56.000 mm (2.2044 to 2.2047 in.)

If the result is not as specified, replace the
crankshaft.

(e) Check each crank pin for taper and out-of-

roundness as shown.
Maximum taper and out-of-roundness:

0.02 mm (0.0008 in.)

If the result is not as specified, replace the
crankshaft.
