Replacing theMain Bushing
Whenever the readings for the main bushings ex-
ceed the repairable limit, they must be replaced.
When fitting the main bushings in the main bush-
ings housing and cylinder block,
observe the fol-
lowing points:
a) To extract and insert bushings, always
use the bushings removing and installing tools.
b)
When inserting new bushings, be sure that
the oil passages are aligned.
C)
After the new bushings have been install-
ed, measure the inner diameter of the main
bushingto check that they are properly aligned,
and
not contracted.

CAMSHAFT
A
single, integrated camshaft, incorporating the in-
take and exhaust cams, and the fuel cam,
is
used.
The fuel cam has straight flank and convex curves
while the intake and exhaust cams have parabolic
acceleration curves, in order to reduce the shock
of inertia force, this also serves to effectively
re
duce noise.
