The grease must have the following characteristics:
• NLGI Grade 2
• Lithium-based
• Water-insoluble
• Anti-rusting
• Anti-oxidizing
• Mechanically stable
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.
NOTE: The UW35 2 speed bearings are
permanently greased bearings and do not require
lubrication.
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. Increase spring tension to
change belt span length. The UW 2 speed belt
tension should be set according to the data
listed in Table 3.
Table 3
Deflection. Refer to Figure 11. Increase
spring tension 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 should be used to set the belt tension.
An operating (normal) force should be used
after the washer-extractor has been operated
for a few hours. Refer to Table 4 for those
values.

c. Verify that V-belts are properly aligned by
checking pulley alignment. Place a
straightedge across both pulley faces. The
straightedge should make contact with the
pulleys in four places. Refer to Figure 12.
