Adjusting V-Belt Tension
WARNING
Accidental or remote starting can
cause severe personal injury or death. Discon-
nect the negative (–) cable at the battery to pre-
vent the engine from starting.
See Table 4-1 for scheduled inspection or replace-
ment. Adjust belt tension as follows:
1. Disconnect the negative ( – ) cable at the battery
to prevent the engine from starting.
2. Remove the front and top access doors. If work
space is limited, remove the end panel (Fig-
ure 4-6) to be able to hold the nut on the pump
pivot bolt (Figure 4-7) with an open-end wrench
while loosening the bolt.
3. Loosen both bolts so that the pump can pivot.
4. Pivot the pump out to tighten belt tension. Hold
tension by tightening the tension adjusting bolt
and check it by applying 20 pounds (10 kg) to
the middle of the pulley span. Belt tension is
correct when deflection is 0.4 inch (10 mm).
5. Tighten the bolts, reassemble the panels and
doors and reconnect the battery cables (nega-
tive [ – ] last).
