Section 4 Service Procedures

WARNING

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.

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-Tensioningsection, 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.
