Piston clearance:
Measure cylinder bore diameter and piston diameter to find
their difference which is piston clearance. Piston clearance
should be within specification as given below. If it is out of
specification, rebore cylinder and use oversize piston.
Piston clearance
: 0.032 – 0.061 mm (0.0013 – 0.0024 in.)
: 0.016 – 0.045 mm (0.0006 – 0.0018 in.) with coating
Ring groove clearance:
Before checking, piston grooves must be clean, dry and free
of carbon deposits.
Fit new piston ring (1) into piston groove, and measure clear-
ance between ring and ring land by using thickness gauge
(2). If clearance is out of limit, replace piston.

Piston Pin
Check piston pin, connecting rod small end bore and piston
bore for wear or damage, paying particular attention to con-
dition of small end bore bush. If pin, connecting rod small
end bore or piston bore is badly worn or damaged, replace
pin, connecting rod and/or piston. NOTE:

thrust direction at two positions.

ing and observe contact pattern. Bearing shells found in
defective condition must be replaced.
Two kinds of rod bearing are available; standard size bearing
and 0.25 mm (0.0098 in.) undersize bearing. For identifica-
tion of undersize bearing, it is painted red at the position as
indicated in figure, undersize bearing thickness is 1.605 –
1.615 mm (0.0632 – 0.0635 in.) at the center of it.

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.

Limit : 0.35 mm (0.0138 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 dif-
ference, 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.

General information
Service main bearings are available in standard size and
0.25 mm (0.0098 in.) undersize, and each of them has 5
kinds of bearings differing in tolerance.
