Motors covered by this Instruction Manual are
equipped with several types of bearings. This descrip-
tion covers regreasable anti-friction bearings only.
Non-regreasable ball bearings require no periodic main-
tenance. See I/M B-3654 for oil mist lubricated anti-
friction bearings procedures.
GREASE LUBRICATED BEARINGS
This motor has been properly lubricated at the time of
manufacture and it is not necessary to lubricate at
time of installation unless the motor has been in stor-
age for a period of six months or more.
Lubrication of anti-friction bearings should be done as
a part of a planned maintenance schedule. The
Recommended Lubrication interval should be used as a
guide to establish this schedule.
Cleanliness is important in lubrication. Any grease
used to lubricate anti-friction bearings should be fresh
and free from contamination. Similarly, care should be
taken to properly clean the grease inlet area of the
motor to prevent grease contamination.
RECOMMENDED LUBRICANT
For motors operating in ambient temperatures shown
below, use the following lubricant or its equal.

LUBRICATION PROCEDURE
Reliance regreasable anti-friction bearings may be lubri-
cated with the motor running or stationary. Stationary
with the motor warm is preferred.
1. Locate the grease inlet, clean the area and replace
the pipe plug with a grease fitting, if the motor is
not equipped with grease fittings.
2.If motor is equipped with grease drain plug, remove
plug and loosen any hardened grease that may
block drain.
3. Add the recommended volume of the appropriate
lubricant using a hand operated grease gun.
4. Run the motor for two hours.
5. Replace the pipe plug in grease drain.
6. Grease may not relieve from drain. Use only vol-
ume shown in Table 3.
LUBRICATION INSTRUCTIONS
1. Select Service Condition from Table 1.
2. Select Lubrication Frequency from Table 2.
3. Select Lubrication Volume from Table 3.
4. Lubricate the motor at the required frequency with
the required lubricant volume in accordance with
LUBRICATION PROCEDURE.
NOTE: Mixing lubricants is not recommended due to
possible incompatibility. If it is desired to change
lubricant, follow instructions for lubrication and repeat
lubrication a second time after 100 hours of service.
Care must be taken to look for signs of lubricant
incompatibility, such as extreme soupiness visible from
the grease relief drain area, or from the shaft opening.
