INSPECTION
Crankshaft
Crankshaft runout
Using a dial gauge, measure runout at center journal. Rotate crank-
shaft slowly. If runout exceeds its limit, replace crankshaft.
Limit on runout: 0.06 mm (0.0023 in.)
Crankshaft thrust play
Measure this play with crankshaft set in cylinder block in the normal
manner, that is, with thrust bearing and journal bearing caps
installed. Tighten crankcase bolts to specified torque in such order
as indicated in figure.
Tightening Torque
(a): 58 N·m (5.8 kg-m, 42.0 Ib-ft)
(b): 27 N·m (2.7 kg-m, 19.5 Ib-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.
Crankshaft Thrust Play
Standard: 0.10 – 0.35 mm (0.0039 – 0.0138 in.)
Limit: 0.42 mm (0.0149 in.)

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 crank-
shaft.
Diameter of journal: 57.982 – 58.000 mm (2.2828 – 2.2834 in.)
Limit on out-of-round and taper: 0.01 mm (0.0004 in.)
