V-BELT TENSION ADJUSTMENT
1. Inspect the V-belt tension.
Standard
[amount of delfection when pressed with 98 N (10 kgf)]
4Y: 8~13 mm (0.31~0.51 in)
1DZ-II: 8~13 mm (0.31~0.51 in)
Standard
[When using a tension gauge (SST)]
SST 09216-76002-71 (09216-00021)
4Y: 294~490 N (30~50 kgf) [66~110 lbf]
1DZ-II: 324~559 N (33~57 kgf) [73~126 lbf]
2. V-belt deflection adjustment
4Y engine vehicle
(1) Loosen the fixing bolt.
(2) Loosen the set bolt and turn the adjustment bolt to adjust
the tension.
(3) Tighten the fixing bolt and recheck the belt tension.
Note:
Be careful not to apply excessive tension to the belt.
1DZ-II engine vehicles
(1) Loosen the fixing bolt and adjusting bolt.
(2) Stretch the V-belt using a pry bar with the length of 300 to
400 mm (11.8 to 15.7 in), and tighten the alternator
adjustment bolt.
(3) Tighten the fixing bolt then recheck the belt tension.
Note:
Adjustment of the tension using a pry bar gives rise to
considerable individual differences, and tends to result in
excessive or insufficent tension. Therefore, be sure to inspect
the deflection amount.
