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: 64.0mm (2.520 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.

Timing Belt Tensioner
1. Install the tensioner and the tensioner spring.
2. Temporarily secure the tensioner with the spring fully ex-
tended.
Timing Belt
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
cylinder head cover marks.
3. Install the timing belt so that there is no looseness at the
tension side.
Caution
l Do not turn the crankshaft counterclockwise.
4. Turn the crankshaft two turns clockwise, and align the tim-
ing belt pulley mark with the timing mark.
5. Verify that the camshaft pulley marks are aligned with the
cylinder head cover mark.
if not aligned, remove the timing belt and repeat from ten-
sioner installation.
6. Loosen the tensioner lock bolt to apply tension to the tim-
ing belt.
Caution
l Be sure not to apply tension other than that of the
tensioner spring.
7. Tighten the tensioner lock bolt.
Tightening torque:
19-25 N#m (1.9-2.6 m-kg, 14-19 ft-lb)
8. Turn the crankshaft 2 turns clockwise and verify that the
timing marks are correctly aligned.
9. Measure the timing belt deflection by applying moderate
pressure (96 N, 10 kg, 22 lb) midway between the crank-
shaft pulley and the camshaft pulley.
If the timing belt deflection is not correct, temporarily se-
cure tensioner lock bolt so the spring is fully extended and
repeat steps 4-8 above or replace the tensioner spring.
Deflection:
11 .O-13.0mm (0.43-0.51 In) at 96 N (10 kg, 22 lb)
