• THRUST WASHER SIDE CLEARANCE
Measure the clearance between the main journal thrust washer
and the crankshaft.
1
Standard
2
0.05 - 0.30 mm
(0.002 - 0.012 in)
3
If the measurement exceeds the service limit, check the thrust
washer and the cylinder block thrust surface. Replace the
4
thrust washer with a new one if necessary and recheck.
If the measurement still exceeds the service limit after
5
replacing the thrust washer, replace the crankshaft with a new
one.

• CRANKSHAFT MAIN BEARING OIL CLEARANCE
1) Clean the crankshaft main journals and main bearings, and
7
check the journals and the bearings for wear or damage.
8
2) Install the four main bearings and crankshaft on the
cylinder block, and install the four main bearings on the
9
crankcase.
3) Install the crankcase on the cylinder block, and tighten the
10
bolts to the specified torque (P. 10-28).
11
4) Remove the crankcase. Set the plastigauge on each main
journal of the crankshaft.
12
• Set the plastigauge in the axial direction.
• Avoid the oil passage in the bearing journal to set the
13
plastigauge.
14
5) Reinstall the crankcase on the cylinder block, and tighten
the bolts to the specified torque (P. 10-28).
15
• Do not turn the crankshaft during this check.
16
6) Remove the crankcase. Measure the compressed width on
the plastigauge using the scale printed on the bag of the
17
plastigauge.
18
• Take the widest width on the plastigauge.
19
Standard
0.021 - 0.039 mm
20
(0.0008 - 0.0015 in)
7) If the measurement exceeds the service limit, replace the
main bearing with an undersize bearing by referring to the
main bearing selection table (P. 10-19). Recheck the oil
clearance.
If the measurement still exceeds the service limit, replace
the crankshaft with a new one.
10-14
