The grease must have adequate base oil
viscosity with one of the following ratings:
• ISO VG 150 (135 – 165 cSt at 40°C or
709 – 871 SUS at 100°F)
• ISO VG 220 (198 – 242 cSt at 40°C or
1047 – 1283 SUS at 100°F)
• An SAE 40 rating is also acceptable as
long as the cSt or SUS values are within
the specified ranges.
Pump the grease gun slowly, permitting
only 2 strokes.
2. Use the following procedures to determine
if V-belts require replacement or
adjustment. Call a qualified service
technician in either case.
a. Check V-belts for uneven wear and
frayed edges.
b. After disconnecting power to the
washer-extractor and removing all
panels necessary for access to the drive
belt, use one of the following
methods to verify that V-belts are
properly tensioned.
• Tension Gauge. Loosen motor
mounting bolts and slide motor
along motor plate to change belt
span length. UWPV belt tension
should be between 70 and 90 pounds
(±5 pounds). Set initial tension
towards the high end of this range.

• Deflection. See Figure 19. Loosen
motor mounting bolts and slide
motor along motor plate to change
belt span length. Belt tension
measurements should be taken as
close to the center of the belt span as
possible. For every inch of span
length, the belt should deflect 1/64
inch (0.40 mm). Thus, a belt with
span length of 50 inches should
deflect 50/64 inch (19.84 mm). 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.
