6. DRIVE BELT (For Water Pump and
Generator) (Inspect for tension)
MOOSBBN
(1) Place straight edge as shown in the illustration.
(2) Measure the deflection with a force of
100 N (22 Ibs.)
applied to belt mid-point between water pump pulley
and generator pulley. If the standard value is not ob-
tained, make adjustment.
Standard value: 9.0-l 1.5 mm (.354-.453
in.)
(3) Use a tension gauge to check the belt tension. If the standard value is not obtained, make adjustment.
When tension gauge is used, the tension may be
measured between any two pulleys.
Standard value:
250-500 N (55-110
Ibs.)
7. ENGINE OIL (Change)MOOSAABc
Always use lubricants which conform to the requirements
of the API classification “For Service SG” or “For Service SG/CD”
when available, and have the proper SAE grade
number for the expected temperature range.
Never
Lose nondetergent or straight mineral oil.
(1) After warming up the engine, remove the oil filler cap.
(2) Remove the drain plug to drain the engine oil. (3) Replace the drain plug gasket with a new one and
tighten the drain plug.
(4) Supply new engine oil through the oil filler.

(5) Start and run the engine a few minutes.
(6) Stop the engine and check the engine oil level.
8. ENGINE OIL FILTER (Change)
MOOSABG
The quality of replacement filters varies considerably. Only high
quatlity filters should be used to assure most efficient
service. Genuine oil filters require that the filter is capable of
withstarlding a pressure of 256 psi are high quality filters
and are recommended as follows:

Caution
1. Before checking, turn the engine one time or more.
2.If the belt tension is too strong, it is possible that the
generator or water pump bearing is damaged.
If the b’elt tension is too weak, however, sounds of its
slipping will be heard, and the belt’s service life will be
reduced.
1.Loosen the generator pivot nut.
2. Loosen the lock bolt of the belt tension adjuster.
3. Using the adjustment bolt, adjust the belt tension to
specified.
4. Tighten the lock bolt.
5.Tighten the generator pivot nut.
6.Check the deflection or the tension of the belt; readjust if
necessary.
NOTE
Even for a new belt, the adjustment value for a used belt
should be used to make the adjustment if the belt has been
used for as long as five minutes or more.
DEFLECTION ADJUSTMENT OF POWER STEERING OIL
PUMP DRIVE BELT
1. Loosen power steering oil pump fixing bolt.
2. Move power steering pump, tension belt moderately and adjust deflection.
3. Tighten fixing bolts.
4. Run the engine one time or more.
5. Check the belt deflection. Readjust, if necessary.
TENSION ADJUSTMENT OF THE AIR CONDITIONING
COMPRESSOR DRIVE BELT
1. Loosen tension pulley fixing bolt A.
2. Adjust belt deflection with adjusting bolt B.
3. Tighten fixing bolt A.
4. Run the engine one time or more. 5. Check the belt tension. Readjust, if necessary.
NOTE
Even for a new belt, the adjustment value for a used belt
should be used to make the adjustment if the belt has been
used for as long as five minutes or more.

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.

7EN20E-1 TSB Revision 22. 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.
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.

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.
