CRANKSHAFT BOLT LOOSENING
CRANKSHAFT SPROCKET REMOVAL
TIMING BELT "9" REMOVAL
(1) 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.
