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 (1) and journal bearing caps
installed.
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.
