INSPECTION
1. TIMING BELT
Check the timing belt closely. Replace the belt with a new
one if any of the following defects is evident:
(1) Hardened backing rubber (the backing rubber is glossy,
non-elastic, and so hard that scratching with fingernails
leaves no mark)
(2) Surface cracks in the backing rubber
(3) Splits in the canvas and/or separation of the canvas and
rubber
(4) Cracks at the bases of teeth
(5) Cracks in the side of the belt
(6) Abnormal wear on the belt’s sides
NOTE
The sides of the belt are normal if they are sharp as
if cut by a knife.
(7) 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)
(8) Missing teeth
2. TENSIONER PULLEY AND IDLER PULLEY
(1) Check that the pulleys turn smoothly without play and
are not abnormally noisy. Replace either or both of the
pulleys if necessary.
