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 size 54.988 ± 55.003 mm
(2.1649 ± 2.1655 in.)
U/S 0.25 54.745 ± 54.755 mm
(2.1553 ± 2.1557 in.)
Crank pin diameter:
STD size 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 clearance
(See pages EM±114 to 117).
(b) 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 maximum,
grind or replace the crankshaft.
3. 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 step 2).
Install new main journal and/or crank pin undersized bear-
ings.
