Timing Belt

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 or immersed in solvent. Replace parts if contaminated. If there is oil or water on each part, check the front case oil seals, camshaft oil seal and water pump for leaks.





Mark the belt running direction for reinstallation.
Loosen the tensioner "B" bolt, and then remove the timing belt "B."

Check the timing belt closely. Replace the belt with a new one if any of the following defects are evident:





Hardening of rubber backing.
Back side is glossy without resilience and leaves no indent when pressed with fingernail.





Surface cracks on the backing rubber.
Cracks or peeling of the canvas.
Cracks on the tooth bottom.
Cracks on the belt sides.





Abnormal wear on the belt sides.

NOTE: The sides of the belt are normal if they are sharp as if cut by a knife.





Abnormal wear on teeth.
Initial stage: Canvas worn (fluffy canvas fibers, rubbery texture gone, white discoloration, canvas texture indistinct)
Final stage: Canvas worn, exposing rubber (tooth width reduced)
Missing teeth.
