Maximum circle runout: 0.06 mm (0.0024 in.)
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
U/S 0.25
Crank pin diameter:
STD
U/S 0.25
If the diameter is not as specified, check the oil clearance
(See pages
(b) Check each main journal and crank pin for taper and
out–of–round as shown.
Maximum taper and out–of–round:
If the taper or out–of–round is greater than maximum, grind
or replace the crankshaft.
