1NZ-FE ENGINE MECHANICAL: DRIVE BELT: INSTALLATION

INSTALLATION

1. INSTALL FAN AND GENERATOR V BELT
(a) Provisionally install the fan and generator V belt onto each pulley.
NOTE: Make sure that the V-belt is securely fitted into the rib groove of the pulley.

2. ADJUST FAN AND GENERATOR V BELT





(a) Insert an adjusting bar between the engine mounting bracket and generator assembly. Push the adjusting bar toward the vehicle front to adjust the generator V belt tension.
NOTE: Do not insert the adjusting bar between the camshaft timing oil control valve assembly and generator assembly. It could damage the camshaft timing oil control valve assembly.





(b) First tighten bolt A, then tighten bolt B.
Torque: 19 Nm (189 kgf-cm, 14 ft-lbf)
Torque: 54 Nm (551 kgf-cm, 40 ft-lbf)
3. INSPECT FAN AND GENERATOR V BELT





(a) Check the V belt deflection and tension.
Deflection:






Tension:





If the belt deflection is not as specified, adjust it.
HINT:
- Check the V belt deflection at the specified point.
- Check the drive belt deflection at the specified point.
- When installing a new belt, set its tension to the specified value.
- When inspecting a belt which has been used for over 5 minutes, apply the used belt specifications.
- When reinstalling a belt which has been used for over 5 minutes, adjust its deflection and tension to the intermediate values of each used belt specification.
- V-ribbed belt tension and deflection should be checked after 2 revolutions of engine cranking.
- When using a belt tension gauge, confirm its accuracy by using a master gauge first.
