d. When assembling, apply a liberal coat of motor
oil to all bearing surfaces.
NOTE:
When applying final torque to the rod
caos. Observe the following procedures:
Apply molybdenum disulfide
grease
to con-
necting rod bolt threads. Apply torque evenly
to both ends of the cap. While tightening, if
a torque of 3.3 m-kg (24 ft-lbs) or more is
reached, DO NOT STOP tightening until
final torque is reached. If tightening is inter-
rupted between 3.3 m-kg and 3.8 m-kg,
loosen the nut to less than 3.3 m-kg and start
again.
Tighten to full torque specification
without pausing.
K.
OIL PUMP
1. Check the clearance between housing and
outer rotor.
Standard clearance:
0.09~0.015mm
(0.0035~0.0059 in.)
2. Check the clearance between outer rotor and
inner rotor.
Standard clearance:
0.03~0.09mm
(0.0011~0.0035 in.)
3. Remove the relief valve and check valve plung-
ers
from oil pump assembly. Check the
plungers for scratches and wear.
L. PRIMARY DRIVE
1. "Hy-Vo" Chain And Primary Gears
The "Hy-Vo" primary chain is
a
plate-and-pin
type that does not use rollers as
in
the case
of
a
conventional motorcycle drive chain. The
plates of the chain form a mating surface for
the primary gear teeth. That is, the primary
gears
actually mesh with the chain plates. This
chain is extremely durable and, under normal
conditions, can be expected to last the life
of the motorcycle engine. However, if obvious
damage is caused through serious oil starva-
tion or abrasive oil contamination, the chain
should be replaced.
2. Clutch Damper
a Remove circlip using a press and special tool.
Press tool on collar no more than necessary to
remove circlip. Damper springs may be dam-
aged if excessive pressure is applied.
b. Inspect damper cam and pin surfaces. Check
for smooth cam action (as illustrated by
arrows). Check for excessive wear on cam and
pin surfaces. If operation is not smooth or cam
surfaces are severely worn, replace damper
assembly.
c. Inspect plate washer and thrust bearing for
wear or damage. Replace as necessary.
