4. Measure the crankshaft thrust wall width (1) for wear
using an inside micrometer. Refer to "Engine
Mechanical Specifications".
5. Measure the crankshaft thrust wall surface (2) for
runout using the J 7872. Refer to "Engine
Mechanical Specifications".
6. If the crankshaft journals are damaged or worn
beyond specifications, the crankshaft may be ground
0.25 mm (0.010 in). There is only 1 size of oversized
main bearings available for service.
7. Inspect the crankshaft main journals for undersize,
using an outside micrometer.
8. Inspect the crankpins for undersize using an outside
micrometer.
9. Compare your measurements with those listed in the
"Engine Mechanical Specifications". If the crankpin
journals are worn beyond the specifications, the
crankshaft may be ground 0.25 mm (0.010 in). There
is only 1 size of oversized connecting rod bearings
available for service.
10. Measure the main bearing and crankpin journals for
out-of-round using the following procedure:
a. Using an outside micrometer, measure the
journal at the extreme front and rear locations on
the journal. Call these points A and B.
b. Measure the journal in 2 new locations exactly
90 degrees from the first points. Call these points
C and D.
c. Subtract A from C and B from D. The differences
will indicate journal out-of-round.
d. The out-of-round should not exceed 0.004 mm
(0.00016 in) maximum.
e. If the journals are worn beyond the
specifications, the crankshaft may be ground
0.25 mm (0.010 in). There is only 1 size of
oversized crankshaft and connecting rod
bearings available for service.
11. Measure the main bearing and crankpin journals for
taper using the following procedure:
a. Using an outside micrometer, measure the
journal at the extreme front (A) and rear (B) of
the journal parallel to the crankshaft centerline.
b. Subtract the smallest from the largest
measurement. The result will be the journal
taper.
c. If the main bearing journal taper exceeds 0.004
mm (0.00016 in), replace the crankshaft.
d. If the journals are worn beyond the
specifications, the crankshaft may be ground
0.25 mm (0.010 in). There is only 1 size of
oversized crankshaft and connecting rod
bearings available for service.
