Ty p e o f s o u n d C o n d i t i o n P o s s i b l e c a u s e
Regular clicking soundSound increases as engine
speed increases.
•Valve mechanism is defective.
•Incorrect valve clearance
•Worn valve rocker
•Worn camshaft
•Broken valve spring
•Trouble of tappet
Heavy and dull clankOil pressure is low.•Worn camshaft main bearing
•Worn connecting rod bearing (large end)
Oil pressure is normal. Damaged engine mounting

injector connector of noisy cyl-
inder is disconnected.
(NOTE*)
•Worn crankshaft main bearing
•Worn bearing at crankshaft end of connecting rod
Knocking sound when engine
is operating under idling speed
and engine is warm
Sound is reduced when fuel
injector connector of noisy cyl-
inder is disconnected.
(NOTE*)
•Worn cylinder liner and piston ring

CAUTION:
When holding the rotor with a vise, place alumi-
num plates or wooden pieces on the vise jaws
to prevent rotor from damage.
5) Remove the ball bearing as follows.
(1) Remove the bolt, and then remove the bear-
ing retainer.
(2) Firmly install an appropriate tool (such as a
fit socket wrench) to bearing inner race.
(3) Push the ball bearing off the front cover us-
ing a press.

puller.
7) Separate the connection between rectifier and
stator coil to remove stator coil.
CAUTION:
Do not allow a 180 — 270 W soldering iron to
contact the terminals for more than 5 seconds
at once because the rectifier cannot withstand
so much heat.
