REMOVAL SERVICE POINTS
CRANKSHAFT PULLEY REMOVAL
Using special tools, remove the crankshaft pulley from the
crankshaft.
Caution
Use only the specified special tools, or a damaged pulley
damper could result.
ENGINE SUPPORT BRACKET REMOVAL
Remove the engine support bracket in the numbered se-
quence shown in the illustration.
Spraying lubricant, slowly remove the bolt (reamer bolt) indi-
cated by the arrow.
Caution
Keep in mind that the reamer bolt is sometimes heat
seized on the engine support bracket.
TIMING BELT REMOVAL
(1) Align the timing marks.
(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 center bolt on the tensioner pulley to remove
the timing belt.
Caution
Water or oil on the belt shortens 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 contami-
nated.
If there is oil or water on each part check the front
case oil seals, camshaft oil seal and water pump for
leaks.
INSTALLATION SERVICE POINTS
AUTO TENSIONER INSTALLATION
(1) If the auto tensioner rod is in its fully extended position,
reset it as follows.
Keep the auto tensioner level and, in that position,
clamp it in the vise with soft jaws.
2) Push in the rod little by little with the vise until the
set hole (A) in the rod is aligned with that (B) in the
cylinder.
