BELT “B” REMOVAL
(1) Make a mark on the back of the timing belt indi cating
the direction of rotation so it may be reassembled in the’
same direction if it is to be reused.

(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 should
not be washed. Replace parts if seriously
(2) If there is oil or water on each part, check fr ont case
