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.
