15. REMOVE TIMING BELT GUIDE
16. REMOVE TIMING BELT
HINT:
When re±using timing belt:
Draw a direction arrow on the timing belt (in the direction of en-
gine revolution), and place matchmarks on the timing belt and
crankshaft timing pulley.
17. REMOVE NO.1 IDLER PULLEY AND TENSION
SPRING
Remove the bolt, pulley and tension spring.
18. REMOVE NO.2 IDLER PULLEY
Remove the bolt and pulley.

3. INSTALL NO.2 IDLER PULLEY
(a) Install the pulley with the bolt.
Torque: 42 N´m (425 kgf´cm, 31 ft´lbf)
HINT:
Use the 35 mm (1.38 in.) long bolt.
(b) Check that the idler pulley moves smoothly.
4. TEMPORARILY INSTALL NO.1 IDLER PULLEY AND
TENSION SPRING
(a) Align the bracket pin hole with the pivot pin.
