BELT
FIG A
FUEL PUMP
FIG C
Note: Some general rules of belt tension are:
• The ideal tension is the lowest tension without belt slippage
• Over tightening decreases belt and bearing life.
• Keep belts clean and free of foreign material that may cause
slippage
• Do not apply belt dressing, which can cause damage and early
belt failure.
6) Re-tighten Tension Bracket mounting bolts (3) and Lower fuel pump
mount bolt (1).
7) Replace belt guard.
WARNING:
Do not operate unless belt guard is in place to prevent access to rotating
parts. Clothing or hair can become rapidly entangled in unguarded rotating
parts, resulting in serious injury or death.
