CRANKSHAFT INSPECTION AND REPAIR
INSPECT CRANKSHAFT FOR CIRCLE RUNOUT
Place the crankshaft on V—blocks.
Using a dial indicator, measure the circle runout at the
center journal.
Maximum circle runout:
0.06 mm (0.0024 in.)
If the circle runout is greater than maximum, replace
the crankshaft.
INSPECT MAIN JOURNALS AND CRANK PINS
Using a micrometer, measure the diameter of each
main journal and crank pin.
Main journal diameter: ,
STD
54.985 — 55.000 mm (2.1648 — 2.1654 in.)
U/S 0.25
54.745 —— 54.755 mm (2.1553 — 2.1557 in.)
Crank pin diameter:
STD
47.985 — 48.000 mm (1.8892 —1.8898 in.)
U/S 0.25
47.745 — 47.755 mm (1.8797 — 1.8801 in.)
If the diameter is not as specified, check the oil clear-
ance (See steps 3 and 6 on pages EG-131 to 134). If
necessary, grind or replace the crankshaft.
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 in.)
If the taper and out—of—round is greater than maxi-
mum, replace the crankshaft.
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).
lnstall new main journal and/or crankshaft pin under-
sized bearings.
