MAIN BEARINGS AND CONNECTING ROD BEARINGSVisually inspect each bearing for peeling, melt, seizure and
improper contact. Replace the faulty bearings.
OIL CLEARANCE MEASUREMENTTo check the oil clearance, measure the outside diameter of
crankshaft journal and crank pin and the inside diameter of
bearing. The clearance can be obtained by calculating the
difference between the measured outside and inside dia-
meters.
Oil clearance:
Crankshaft main bearing
0.02-0.05 mm (.OOOS-.0019 in.)
Connecting rod bearing
0.02-0.05 mm (.OOOS-.0019 in.)
Limit:
Crankshaft main bearing0.1 mm (.004 in.)
Connecting rod bearing0.1 mm (.004 in.)
PLASTIC-GAUGE METHODPlastic-Gauge may be used to measure the clearance.
(1)Remove oil and grease and any other dirt from bearings and
journals.(2) Cut Plastic-Gauge to the same length as the width of the
bearing and place it in parallel with the journal, off oil holes.(3) Install the crankshaft, bearings and caps and tighten them
to the specified torques. During this operation, do NOT turn
the crankshaft. Remove the caps. Measure the width of the
Plastic-Gauge at the widest part by using
a scale printed onthe Plastic-Gauge sleeve.
If the clearance exceeds the limit, the bearing should be
replaced or an undersize bearing used.
When installing a new crankshaft, be sure to use standard
size bearings.Should the standard clearance not be obtained even after
bearing replacement, the journal should be ground to
undersize and a bearing of the same size should be
installed.
OIL SEALCheck front and rear oil seals for damage or worn lips.
Replace any seat that is faulty.

INSPECTIONWSKCACTIMING BELTS
The timing belts must be checked closely. Should the followingdefects be evident, replace the belt with a new one.
(1) Hardened back surface rubber
Glossy, non-elastic, and so hard that no mark is produced
even when scratched by a
fingernai.1.(2) Cracked back surface rubber.
(3) Cracked or separated canvas.
(4) Cracked tooth bottom.
(5) Cracked side.J(6) Abnormal wear on side.
NOTE
Normal belt should have clear-cut sides as if cut by a sharp
knife.(7) Abnormal wear on teeth.
Initial stage:
Canvas on load side tooth flank worn (Fluffy canvas
fibers, rubber gone and color changed to white, and
unclear canvas texture)
Final stage:Canvas on load side tooth flank worn down and rubber
exposed (tooth width reduced)
(8) Missing tooth.
TENSIONER PULLEY AND IDLER PULLEY
(1) Turn the pulleys to check for possible binding, excessive
play, and unusual noise. Replace the pulley if any of these
defects is evident.
(2) Replace if there is a grease leak.

I1 EN067-(2) Measure the journal O.D. and main bearing I.D. to obtain
the clearance between the two (oil clearance). If the
clearance exceeds the limit, replace the main bearing and,if necessary, the crankshaft.
Standard value:
0.02-0.05 mm (.OOOS-.0020 in.)
Limit: 0.1 mm
(.0040 in.)
Caution
A special
surface treatment has been applied to
crankshaft. Do not machine it to undersize.
CRANKSHAFT OIL CLEARANCE (PLASTIC GAUGE
METHOD)
The crankshaft oil clearance can be measured easily by using aplastic gauge, as follows:
(1) Remove oil and grease and any other foreign matters from
crankshaft journal and bearing inner surface.
(2) Install the crankshaft.
(3) Cut the plastic gauge to the same length as the width of
bearing and place it on journal in parallel with its axis.
(4) Gently place the crankshaft bearing cap over it and tighten
the bolts to the specified torque.
(5) Remove the bolts and gently remove the crankshaft
bearing cap.(6) Measure the width of the smashed plastic gauge at its
widest section by using a scale printed on the plastic gauge
bag.
