Crankshaft thrust play
Tighten crankcase bolts according to next procedure.
1) Tighten bolts to to 41 N·m (4.1 kg-m, 29.5 lb-ft) in order
of their numbers.
2) Tighten bolts to to 17 N·m (1.7 kg-m, 12.0 lb-ft) in order
of their numbers.
3) In the same manner as in 1), tighten them to specified torque.
4) In the same manner as in 2), tighten them to specified torque.
Tightening Torque

: 58 N·m (5.8 kg-m, 42.0 lb-ft)
to : 24 N·m (2.4 kg-m, 17.5 lb-ft)

Use a dial gauge to read displacement in axial (thrust) direction of
crankshaft.
If its limit is exceeded, replace thrust bearing with new standard
one or oversize one to obtain standard thrust play.
Out-of-round and taper (uneven wear) of journals
An unevenly worn crankshaft journal shows up as a difference in
diameter at a cross section or along its length (or both). This differ-
ence, if any, is determined by taking micrometer readings.
If any one of journals is badly damaged or if amount of uneven wear
in the sense explained above exceeds its limit, regrind or replace
crankshaft.
Limit on out-of-round and taper: 0.01 mm (0.0004 in.)
