SERVICE POINTS OF REMOVALMl 1KBDG
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.
