TIMING BELT
Caution
l Never forcefully twist, turn inside out, or bend the
timing belt.
l Do not allow oil or grease on the belt.
1. Replace the timing belt if there is any oil or grease on it.
2. Check the timing belt for damage, wear, peeling, cracks,
and hardening. Replace the timing belt if necessary.
TENSIONER, IDLER
Caution
l Do not clean the tensioner or idler with cleaning
fluids. If necessary, use a soft rag to wipe them
clean, and avoid scratching them.
1. Check the tensioner and idler for smooth rotation and ab-
normal noise. Replace the tensioner or idler if necessary.
TENSIONER SPRING
1. Measure the free length of the tensioner spring. Replace
the tensioner spring if necessary.
Free length: 58.8mm (2.315 in)
PULLEY
Timing Belt Pulley, Camshaft Pulley
Caution
l Do not clean the pulleys with cleaning fluids. If
necessary, use a soft rag to wipe them clean, and
avoid scratching them.
1. Inspect the pulley teeth for wear, deformation, and other
damage. Replace the pulley if necessary.

1. Verify that the timing belt pulley mark is aligned with the tim-
ing mark.
2. Verify that the camshaft pulley marks are aligned with the
seal plate marks.
3. Install the timing belt so that there is no looseness at the
idler side or between the camshaft pulleys.
4. Install the pulley boss and pulley lock bolt.
Caution
l Do not turn the crankshaft counterclockwise.
5. Turn the crankshaft two turns clockwise and face the pin
on the pulley boss upright.
