ENGINE – Timing BeltENGINE – Timing Belt11-17
ETIMING BELT “B” REMOVAL
Make a mark on the back of the timing belt indicating the
direction of rotation so it may be reassembled in the same
direction if it is to be reused.
NOTE
(1) Water or oil on the belt shortens its life drastically, so
the removed timing belt, sprocket, and tensioner must
be free from oil and water. These parts should not be
washed. Replace parts if seriously contaminated.
(2) If there is oil or water on each part check front case
oil seals, camshaft oil seal and water pump for leaks.
FCOUNTERBALANCE SHAFT SPROCKET
REMOVAL
(1) Set the special tool as shown to prevent the
counterbalance shaft sprocket from turning together.
(2) Loosen the bolt and remove the sprocket.
GCRANKSHAFT SPROCKET “B” REMOVAL
If it is difficult to remove the sprocket, use the special tool.
HCAMSHAFT SPROCKET BOLT LOOSENING
Use a wrench to hold the hexagonal part of the camshaft,
and then remove the camshaft sprocket mounting bolt.
INSTALLATION SERVICE POINTS
ACAMSHAFT SPROCKET BOLT TIGHTENING
Using a wrench, hold the camshaft at its hexagon and tighten
the bolt to the specification.
