MAINTENANCE, Continued
If water is detected in the gearbox motor adapter and the
oil level is not excessively low, drain the remaining oil
and flush with light oil or kerosene, install new oil seals
and refill with fresh oil.
If any oil has accumulated in the mixer housing, it is the
result of leakage past the gearbox output shaft seal and
will ultimately leak through the bearings. The source of
the problem must first be remedied and then the mixer
driveshaft bearings and oil seal should be replaced after
thoroughly cleaning the inside of the housing.
When reassembling the mixer, replace the o-ring seals in
the mixer housing and apply a sealant, such as silicone
or "Permatex", around the face of the motor flange,
inside of the mounting bolt circle. Apply an anti-seize
compound on the motor shaft and reassemble the motor
to the gearbox. Check the motor to be sure all openings
are plugged and that the conduit box gaskets are in good
condition.

LUBRICATION

The gear box is considered "lubricated for life". It is
factory filled with an AGMA #7C gear lubricant, which is
suitable for an ambient temperature range from 30° to
100° F. If the application calls for outdoor installation in
extremely cold or extremely warm temperatures, or in
corrosive environments, consult the factory.
If it becomes necessary to change the gear lubricant, a
drain plug is conveniently provided on the bottom of the
gear housing under the motor pinion shaft. A fill plug is
located on the top of the housing, above the output gear.
Refill with 14 ounces of the recommended lubricant.
In the Food and Drug Industry (including animal food),
consult the lubrication supplier for recommendation of
lubricants which are acceptable to the Food and Drug
Administration and/or other authoritative bodies having
jurisdiction. Factory supplied oil is not suitable for these
applications or this industry.
Stuffing Box Lubrication
In addition to the coating of lubricant that was applied
during assembly, it is important to completely fill the
voids in the seven-ring box with lubricant. No further
lubricant is required for the two-ring box.
1. Remove the lubricant relief pipe plug on the side of
the stuffing box.
2. Supply lubricant at the grease fitting on the other
side of the box until it begins to flow out of the relief
opening.
3. Install the pipe plug and supply a small amount of
additional lubricant to ensure that all voids in the box
are filled.
