NO9KBBCa2. REMOVAL OF ENGINE MOUNT BRACKET
a(1) Jack up the vehicle after placing a wooden block
:.between the jack and the engine’s oil pan.
CautionJack up carefully so as not to apply an excessive
load to the various parts.
(2) Remove the engine mount bracket.
19. 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 thesame 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 direction.
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 whileremoved, and never wash them. Parts that haveic
*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 camshaft oil seal on the front of the
engine.

24. 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
(.31in.)] to block the left silent shaft.
(3) Remove the oil pump sprocket nut.
(4) Remove the oil pump sprocket.
28. 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.
CautionWater 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 caseoil seals, camshaft oil seal and water pump for leaks.
INSPECTIONNOSKCADTIMING BELTS
The timing belts must be checked closely. Should the followingdefects 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.
