Starter/Generator Belt Tension
Tool List Qty. Required
Belt tension gauge ...................................................... 1
Wrench, 3/4" ............................................................... 1
Wrench, 9/16" ............................................................. 2
Ratchet, 3/8" drive....................................................... 1
Socket, 3/4", 3/8" drive................................................ 1
The starter/generator belt tension should be checked
after the first 15 - 20 hours of operation and set to 75 - 80
lbs (34 - 36 kg.).
A loose belt can cause audible vibration and
squeal.
Tighten a new starter/generator belt to 90 - 110 lbs (41 -
50 kg) tension when a gauge is applied half way between
the two pulleys (Ref. Fig. 26 on page 13).
Although not as accurate, the belt may be depressed
with a finger. A maximum deflection of 3/8" (10 mm) is
acceptable (Ref. Fig. 27 on page 13).
Re-tighten an existing belt to 75 - 80 lbs (34 - 36 kg) ten-
sion using the same technique. A maximum deflection of
1/2" (13 mm) is acceptable.
Adjusting the Belt
Using a 3/4" socket and open end wrench, loosen the
starter/generator pivot bolt.
While holding the lower adjusting nut with a 9/16"
wrench, loosen the upper jam nut with another 9/16"
wrench. Move the lower nut up or down the adjustment
bolt until proper belt tension is achieved. Hold the lower
nut in place and tighten the upper jam nut against it (Ref.
Fig. 28 on page 13).
Using a 3/4" socket and open end wrench, tighten the
starter/generator pivot bolt.
