REMOVAL SERVICE POINTS

TIMING BELT REMOVAL

(1) If the timing belt is to be reused, chalk an arrow mark

on the back surface of the belt so that the belt can be
reinstalled in the same direction.

(2) Place the exhaust camshaft sprocket in a position where

the timing mark for No. 1 cylinder is positioned about
one tooth before the top dead center of the compression
stroke.

Caution
The camshaft sprocket on the exhaust side can turn
very easily because of the valve spring tension. Use
care not to allow your fingers to get caught by the
sprocket.

(3) Loosen the lock nut of the tensioner pulley, then remove

the timing belt.

TIMING BELT “B” REMOVAL

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.

NOTE
(1) 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 contaminated.

(2) If there is oil or water on each part check front case

oil seals, camshaft oil seal and water pump for leaks.
