6) Inspect the bushing at connecting rod small end,
and replace if worn or damaged. Also measure the
piston pin clearance at the connecting rod small
end.
Clearance between piston pin and bushing:
Standard
0 — 0.022 mm (0 — 0.0009 in)
7) Replacement procedure is as follows.
(1) Remove the bushing from connecting rod
with ST and press.
(2) Press the bushing with ST after applying oil
on the periphery of bushing.

ing to remove chips.
6. CRANKSHAFT AND CRANKSHAFT
BEARING
1) Clean the crankshaft completely, and check it for
cracks using red lead. Replace if defective.
2) Measure the bend of crankshaft. If it exceeds the
limit, repair or replace it.
NOTE:
If a suitable V-block is not available, install #1 and
#5 crankshaft bearing on cylinder block, position
the crankshaft on these bearings, and then mea-
sure the crankshaft bend using a dial gauge.
Crankshaft bend limit:
0.035 mm (0.0014 in)
3) Inspect the crank journal and crank pin for wear.
If they are not within the specifications, replace the
bearing with a suitable (undersize) one, and re-
place or recondition crankshaft as necessary.
When grinding the crank journal or crank pin, finish
them to the specified dimensions according to the
undersize bearing to be used.
