Trolley Drive Assembly
Refer to MHP0306 in the Product Parts Information
Manual.
The gear housing is filled at the factory and shipped
with oil, a non-toxic, high quality, Extreme Pressure
(EP), rust- and oxidation-inhibiting worm gear AGMA
#7 lubricant that is suitable for an ambient temperature
of 50° F to 125° F (10° C to 52° C).
Fill gear housing (212) through vented fill plug (210)
hole to height of level plug (201) hole located in cover
(202). The gear housing oil capacity is approximately
0.3 gals (1.5 ltr).
After first 50 hours of operation oil should be changed.
Thereafter it should be changed every 100 hours of
service or every 6 months, whichever occurs first.
The oil is drained by removing pipe plug (213) located
underneath gear housing (212). If oil drains too slowly,
removing vented fill plug (210) may speed up draining.
The oil should be replaced using one of the
recommended lubricants or its equivalent.

Reduction Gear Assembly
Refer to
The reduction gear assembly is shipped with oil from
the factory. Check oil level before initial hoist
operation. If hoist is used at a normal frequency replace
oil in reduction housing once every year.
To ensure correct performance, highest efficiency and
long life, it is essential that lubricating oil be
maintained at correct level. Oil capacity for reduction
gear assembly is 1.1 gals (4.2 ltr).

• Do not over fill. Excess oil will reduce
operating efficiency and increase oil
temperature.
Use only high quality lubricants in reduction gear
assembly such as synthetic gear oil or high grade EP4
gear oil.
The recommended grade of oil must be used at all
times since use of unsuitable oil may result in
excessive temperature rise, loss of efficiency and
possible damage to gears. Check vented fill plug is
unrestricted.
Disc Brake
Refer to MHP0353 in the Product Parts Information
Manual.
The disc brake housing is filled and shipped with oil
from the factory. Check oil level before initial hoist
operation. If hoist is used at a normal frequency replace
oil in disc brake housing six months.
To ensure correct performance, highest efficiency and
long life, it is essential that lubricating oil be
maintained at correct level. Oil capacity for disc brake
housing is 0.2 gals (0.76 ltr).

Use only high quality lubricants in disc brake housing
assembly same as reducer oil.
The recommended grade of oil must be used at all
times since use of unsuitable oil may result in
excessive temperature rise, loss of efficiency and
possible damage to brake discs and sprig clutch. Fill
brake housing (27) to height of level plug (28).
