SERVICE POINTS OF REMOVALMllKBDF
2. REMOVAL OF ENGINE MOUNT BRACKET
(1) Jack up the vehicle after placing a wooden block
between the jack and the engine’s oil pan.
Caution
Jack up carefully so as not to apply an excessive
load to the various parts.
(2) Remove the engine mount bracket.
20. REMOVAL OF TIMING BELT
(1) Turn the crankshaft clockwise and align the timing
marks.
Caution
The crankshaft must always be turned clockwise.
(2) 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.
(3) Loosen the bolt and tension spacer of the timing belt tensioner.
(4) Move the timing belt tensioner to the water pump side and loosely tighten the bolt so that the tensioner
doesn’t return; then remove the timing belt.
NOTE
If the timing belt is to be re-used, use chalk to mark (on
its flat side) an arrow indicating the clockwise direc-
tion.
Caution
1. As water or oil on the belt can seriously reduce
its usable life, ensure that the timing belt,
sprocket, and tensioner stay clean and dry while
removed, and never wash them. Parts that have
become too dirty should be replaced.
2. When any of the parts are oily, check to see
whether there are any oil leaks in any of the oil
seals or the cam shaft oil seal on the front of the
engine.

(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.
26. 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.
INSPECTIONMIlKCAD
TIMING BELTS
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.

(8) Missing tooth.
TENSIONER PULLEY
Turn the pulleys to check for possible binding, excessive play, and unusual noise. Replace the pulley if any of these defects is
evident.
SERVICE POINTS OF INSTALLATION

29. INSTALLATION OF CRANKSHAFT SPROCKET “B”
Install the crankshaft sprocket “B” as shown while paying
attention to its direction.
28. 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.
26. INSTALLATION OF TIMING BELT “B”
(1) Ensure that crankshaft sprocket “B” timing mark and the 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.

tensioner . ADJUSTMENT OF TIMING BELT “B” TENSION
(1) Temporarily fix the timing belt “B”
tensioner such that
the centre of the tensioner pulley is to the left and
above the centre of the installation bolt, and temporari-
ly 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
tensio,ier.
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.
(3) To ensure that the tension is correct, depress the belt (point A) with a finger.
If not, adjust.
Standard value: 5-7 mm (.20-.28

in.)

20. INSTALLATION OF TIMING BELT
(1) Ensure that the timing marks of the camshaft sprock- et, the crankshaft sprocket, and the oil pump sprocket
are all aligned.
(2) When aligning the timing mark of the oil pump sprocket, remove the plug of the cylinder block; then
insert the shaft of a cross-tip
(+) screwdriver with a
shaft diameter of 8 mm
(.31 in.) into the plug hole and
check to be sure that the screwdriver’s shaft can be
inserted at least 60 mm (2.36 in.). Do not remove the
screwdriver until the timing belt is completely at-
tached.
If the screwdriver’s shaft can be inserted only to a
depth of about 20 to 25 mm
(.79 to .98 in.) because it
contacts the silent shaft, turn the sprocket by one rotation and align the timing mark once again; then
check again to be sure that the screwdriver’s shaft can be inserted at least 60 mm (2.36 in.).
(3) Install timing belt. While making sure that tension side
of belt is not slackened, install timing belt onto
crankshaft sprocket, oil pump sprocket and camshaf
t
sprocket in that order.
Caution
If the timing belt is reused, install so that the arrow
marked on it at the time of removal is pointing in
the clockwise direction.
l ADJUSTMENT OF TIMING BELT TENSION
(1) Loosen tensioner mounting bolt. By so doing, tension- er will be moved by spring and will apply tension to
belt.
(2) Recheck to be sure that each sprocket’s timing mark iscorrect.

(3) Turn the crankshaft clockwise by two teeth of the
camshaft sprocket.
Caution
As the purpose of this procedure is to apply the
proper amount of tension on the timing belt, be sure
not to rotate the crankshaft counter-clockwise or
place pressure on the belt to check the amount of
tension.

(4) Apply force on tensioner toward turning direction, (inthe direction of the arrow) such that no portion of the
belt raises out in portion A, place the belt on the
camshaft sprocket such that the belt sprocket teeth
are fully engaged.
(5) Tighten the tensioner installation bolt and tensioner spacer in that order.
Caution
If the tensioner spacer is tightened first, the ten-
sioner will rotate with it and belt tension be thrown
out of adjustment. Always tighten the bolt first.

(6) Check to see that the clearance between the outside of the belt and the cover are within the standard value
by grasping the tension side (between the camshaft
sprocket and oil pump sprocket) of the centre part of
the timing belt between the thumb and index finger.
