5. CONNECTING ROD
1) Replace the connecting rod, if the large or small
end thrust surface is damaged.
2) Check for bend or twist using a connecting rod
aligner. Replace the connecting rod if it has the
bend or twist.
3) Install the connecting rod fitted with bearing to
crankshaft and measure the thrust clearance. If the
clearance exceeds the standard or offset wear oc-
curs, replace the connecting rod.
Connecting rod thrust clearance:
Standard
0.070 — 0.330 mm (0.0028 — 0.0130 in)
4) Inspect the connecting rod bearing for scar,
peeling, seizure, melting, wear, etc.
5) Measure the oil clearance on each connecting
rod bearing using plastigauge. If any oil clearance
is not within the standard, replace the defective
bearing with a new one of standard size or under-
size as necessary. (See the table below.)
Connecting rod oil clearance:
Standard
0.016 — 0.043 mm (0.0006 — 0.0017 in)
6) Inspect the bushing at connecting rod small end,
and replace if worn or damaged. Also measure the
piston pin clearance at connecting rod small end.

with ST and press.
(2) Press the bushing with ST after applying oil
on the periphery of bushing.

(3) Make two 3 mm (0.12 in) holes in bushing.
Ream the inside of bushing.
(4) After completion of reaming, clean the bush-
ing to remove chips.
6. CRANKSHAFT AND CRANKSHAFT
BEARING
1) Clean the crankshaft completely, and check it for
cracks using liquid penetrant tester. Replace if de-
fective.
2) Check the crankshaft for bend, and repair or re-
place if needed. Repair or replace if bended.
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 check
the crankshaft bend using a dial gauge.
3) Inspect the crank journal and crank pin for wear.
If they are not within the specification, replace the
bearing with a suitable (undersize) one, and re-
place or readjust crankshaft as necessary. When
grinding the crank journal or crank pin, finish them
to the specified dimensions according to the under-
size bearing to be used.

4) Measure the thrust clearance of crankshaft at
center bearing. If clearance exceeds the standard,
replace the bearing.
Crankshaft thrust clearance:
Standard
0.030 — 0.115 mm (0.0012 — 0.0045 in)
5) Inspect individual crankshaft bearings for signs
of flaking, seizure, melting and wear.
6) Measure the oil clearance on each crankshaft
bearing using plastigauge. If the measured value is
out of standard, replace the defective bearing with
an undersize one, and replace or recondition the
crankshaft as necessary.

E: INSPECTION
1. ARMATURE
1) Check the commutator for any sign of burns of
rough surfaces or stepped wear. If it has minor
wear, correct it by using sand paper (#300).
2) Run-out test
Check the commutator for run-out, and then re-
place if it exceeds the limit.
Commutator run-out:
Standard
3.1 mm (0.1220 in)
Service limit
Less than 3.8 mm (0.1496 in)
3) Armature short-circuit test
Check the armature for short circuit by placing it on
growler tester. Hold an iron sheet (thickness
gauge, etc. ) against the armature core while slowly
rotating the armature. A short-circuited armature
will cause the iron sheet to vibrate and to be attract-
ed to core. If the iron sheet is attracted or vibrates,
the armature, which is short-circuited, must be re-
placed or repaired.
4) Armature discontinuity test
Using a circuit tester, touch one probe to the Arma-
ture and the other to commutator. No continuity is
normal. If there is continuity, the armature is
grounded.
Replace the armature if it is grounded.
2. OVERRUNNING CLUTCH
Inspect the teeth of pinion for wear and damage.
Replace if it is damaged. Rotate the pinion in the
right direction of rotation (counterclockwise). It
should rotate smoothly. But in the opposite direc-
tion, it should be locked.
CAUTION:
Do not clean the overrunning clutch with oil to
prevent grease from flowing out.
3. BRUSH AND BRUSH HOLDER
1) Brush length
Measure the brush length, and then replace if it ex-
ceeds the service limit.
Replace if abnormal wear or cracks are noticed.
