To reduce the risk of electrical shock, fire, explosion, serious injury or death:
• Disconnect electrical power to the washer-extractor before servicing it.
• Close the gas shut-off valve to the washer-extractor (when applicable) before servicing it.
• Never start the washer-extractor with any guards/panels removed.
• Whenever ground wires are removed during servicing, these ground wires must be
reconnected to ensure that the washer-extractor is properly grounded.

WARNING
26. DRIVE BELT REMOVAL AND
REPLACEMENT
Refer to Figure 10.
If the drive belt is generating noise or if the AC
drive is generating faults because of excessive
hertz fluctuations, first inspect the belt for wear. If
the belt has uneven wear or frayed edges, replace
it. Refer to the Removal and Replacement
sections, below. If the drive belt isn’t noticeably
worn, check the belt’s tension and deflection.
Refer to the Drive Belt Re-Tensioning section,
below.
REMOVAL
a. Turn off power to the machine.
b. Remove the rear panel. Refer to Paragraph 24.
c. Relieve the belt’s tension by loosening the nuts
on the motor mounting plate bolt.
d. Remove the belt from the motor and basket
pulleys.
REPLACEMENT
a. Install the belt onto the motor and basket
pulleys.
b. Re-tension the belt. Refer to Drive Belt Re-
tensioning, below.
c. Replace the rear panel. Refer to Paragraph 24.
DRIVE BELT RE-TENSIONING
Refer to Figure 11.
a. Turn off power to the machine.
b. Remove the rear panel. Refer to Paragraph 24.
c. Check drive belt tension.
(1) Using a tension gauge, check the drive belt
tension. Belt tension should be between 70
and 90 pounds (± 5 pounds). Set the initial
belt tension toward the high end of the
range.
(2) To adjust the drive belt tension, loosen or
tighten the nuts on the motor mounting
plate bolt. Refer to Figure 10.
d. Check the belt deflection.
(1) Belt deflection measurements should be
taken as close to the center of the belt span
as possible.
(2) For every inch of span length, the drive belt
should deflect 1/64 inch (.4 mm). For
example, a belt with a span length of 50
inches should deflect 50/64 inch (19.84
mm).
(3) An initial (run-in) force of 5.25 pounds
should be used to set the belt tension. An
operating (normal) force of 3.5 pounds
should be used after the washer-extractor
has been operated for a few hours.
e. Replace the rear panel. Refer to Paragraph 24.
