Use of special tool belt tension gauge
• Set upper O-ring G of 0 belt tension gauge to 98 N·m {72 lbf.ft,
10 kgf·m} (push load) on graduation H.
• Set lower O-ring J of 0 belt tension gauge to graduation K (maximum
flex of belt).

• Place 0 belt tension gauge at the center of V-belts 1, 2 perpendicu-
larly as illustrated and push top L all the way down until upper O-ring
G hits upper edge M.

• Measure the extent of flex A of V-belts 1, 2 at this point, and if the
measured value deviates from the standard value, adjust as follows:

[Adjustment]
(1) Adjustment of tension of V-belt for fan
• Loosen alternator mounting bolts N (two points), and adjust the
tension of V-belts 2 by moving adjusting bolt P.
• After adjustment, tighten the bolts N, P securely.
CAUTION–
• Bear in mind that excessive tension of V-belts 2 might damage
the belts and bearings that engage with the V-belts.
• Be sure to replace V-belts 2 as a set to maintain even tension
between them.
• Be careful not to let oil stick to V-belts 2. If oil gets onto the
belts, it causes slipping, resulting in overheating and insuffi-
cient battery charging.
(2) Adjustment of tension of V-belt for air-conditioner
• Loosen tension pulley mounting nut Q, and adjust the tension of
V-belt 1 moving adjusting bolt R.
• After adjustment, tighten mounting nut Q securely.
CAUTION–
• Bear in mind that excessive tension of V-belt 1 might damage
the belt and bearings that engage with the V-belt.
• Be careful not to let oil stick to V-belt 1. If oil gets onto the belt,
it causes slipping, resulting in poor performance of the air
conditioner.
