3. REMOVAL OF ENGINE MOUNT BRACKET
(1) With a wooden block placed against the oil pan part ofthe engine, jack up the vehicle.
Caution
Jack up gently, so as not to apply a load to the
various parts.
(2) Remove the engine mount bracket.
4. REMOVAL OF DRIVE BELT Before removing the drive belt, loosen the water pump
pulley mounting bolts.
19. REMOVAL OF AUTO TENSIONER (1) Turn the crankshaft clockwise and align the
timing
marks so as to bring the No. 1 cylinder to compresslon
top-dead-centre position.
At this time the timing marks of the camshaft sprocket
and the upper surface of the cylinder head should
coincide, and the dowel pin of the camshaft sprocketshould be at the upper side.
Caution
The crankshaft must always be rotated clockwise.
(2) Remove the auto tensioner.

20. REMOVAL OF TIMING BELTMake 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.
Caution
Water or oil on the belt shorten 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. If there is oil or water on each part check the front case
oil seals, camshaft oil seal and water pump for leaks.
24. REMOVAL OF CAMSHAFT SPROCKETS
(1) Using a wrench, hold the camshaft at its hexagon
(between the No.2
and No.3
journals) and remove the
camshaft sprocket bolt.
CautionLocking the camshaft sprocket with a tool damages
the sprocket.
(2) Remove the camshaft sprockets.
25. REMOVAL OF OIL PUMP SPROCKET
(1) Remove the plug on the side of the cylinder block.
(2) Insert
a Phillips screwdriver [shank diameter 8 mm
(.31
in.)] to block the left silent shaft.
(3) Remove the oil pump sprocket nut.
(4) Remove the oil pump sprocket.
31. REMOVAL OF TIMING BELT “B” 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.
Caution
Water or oil on the belt shorten 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.
If there is oil or water on each part check the front case
oil seals, camshaft oil seal and water pump for leaks.

INSPECTION
TIMING BELTS MIlKCAC
The timing belts must be checked closely. Should the following
defects 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 fingernail.
(2) Cracked back surface rubber.
(3) Cracked or separated canvas
(4) Cracked tooth bottom.
(5) Cracked side.
(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.

AUTO TENSIONER
(1) Check the auto tensioner for possible leaks and replace as necessary.
(2) Check the rod end for wear or damage and replace as necessary.
(3) Measure the rod protrusion. If it is out of specification, replace the auto tensioner.
Standard value: 12 mm (.47 in.)
(4) Using a vise with soft jaws push in the auto tensioner rod. If the rod can be easily retracted, replace the auto
tensioner. You should feel a fair amount of resistance when
pushing the rod in.
Caution
1.Clamp the auto tensioner in the vise so it maintains
a level position.
2. If the plug at the bottom of the auto
tensioner
protrudes, surround it with a plain
Lvasher as
illustrated to prevent the plug from being in direct
contact with the vise.

Install the crankshaft sprocket “B” as shown while paying
attention to its direction.
33. INSTALLATION OF SPACER (1) Apply a thin coat of engine oil to the outer circumfer-ence of the spacer.
(2) Install the spacer with the chamfered end facing the oil
seal.
NOTE
If the spacer is installed adversely, the oil seal may be
damaged, resulting in the oil leaks.
31. INSTALLATION OF TIMING BELT “B” (1) Ensure that crankshaft sprocket “B” timing mark andthe silent shaft sprocket timing mark are aligned.
(2) Fit timing belt
“B” over crankshaft sprocket “B” and
the silent shaft sprocket. Ensure that there is no slack in
the belt.
. ADJUSTMENT OF TIMING BELT “B” TENSION (1) Temporarily fix the timing belt “B” tensioner such thatthe center of the tensioner pulley is to the left andabove the center of the installation bolt, and temporarily
attach the tensioner pulley so that the flange is toward
the front of the engine.
(2) Holding the timing belt “B” tensioner up with your
finger in the direction of the arrow, place pressure on
the timing belt so that the tension side of the belt is
taut. Now tighten the bolt to fix the tensioner.
Caution
When tightening the bolt, ensure that the tensioner pulley shaft does not rotate with the bolt. Allowing
it to rotate with the bolt can cause excessive
tension on the belt.
