THE FOLLOWING CHART IS BASED ON MOTORS WITH GREASE LUBRICATED
BEARINGS, RUNNING AT SPEEDS OF 1750 R.P.M. OR LESS, AND OPERATING
WITHIN AN AMBIENT TEMPERATURE RANGE OF BETWEEN 0 DEGREES F. TO
120 DEGREES F.
Typical lubricants that can be used:
Chevron Oil Co. - SRI#2 Gulf Rening Co. - Precision #2 or #3
Shell Oil Co. - Alvania #2, Dolium R Mobile Oil Co. - Mobilux Grease #2
Texaco Inc. - Premium RB Sinclair Rening Co. - A.F.#2
REDUCERS
The following reducer information is concerned primarily with wormgear reducers. If your conveyor is equipped with another
type, refer to the manufacturer’s recommendations for installation and maintenance sent along at time of shipment.
1. ASSEMBLE / DISASSEMBLE MOTOR TO REDUCER & RATIO MULTIPLIER (IF USED) - Because many of
today’s motor keyways are cut with a sidemill cutter, the following assembly instructions should be followed to insure
a trouble-free t between motor and reducer. First, place the key into the reducer keyway. Second, line up the
motor keyseat with the key and push the motor shaft into the reducer bore. Third, nish assembly be bolting the motor
to the reducer ange. This procedure should insure that the key does not slide back in the motor keyseat.

NO!
IF MOTOR SHAFT HAS A KEYSEAT MADE BY AN ENDMILL NO SPECIAL ASSEMBLY STEPS ARE REQUIRED.
THE CORRECT ASSEMBLY PROCEDURE IS TO PLACE THE KEY INTO THE REDUCER KEYWAY.
THEN LINE UP MOTOR KEYSEAT WITH KEY IN REDUCER. PUSH MOTOR SHAFT ONTO REDUCER
AND BOLT TOGETHER.
MANY OF TODAY'S MOTORS HAVE KEYSEATS
CUT WITH A SIDEMILL CUTTER. IF YOU
PLACE THE KEY IN THE MOTOR KEYSEAT
IT CAN SLIDE BACK AS THE MOTOR SHAF
T
IS PUSHED INTO THE HOLLOW INPUT SHAFT
OF THE REDUCER. THIS CAN CAUSE THE
HOLLOW INPUT SHAFT TO BREAKOUT
RUINING THE SEALS, ALLOWING OIL LEAKAGE,
AND FURTHER DAMAGE.
NOTE: IT IS ALSO ADVISABLE TO APPLY FEL-PRO C5A ANTISEIZE OR MOBILETEMP 78 GREASE TO THE
BORE OF THE REDUCER THIS WILL MAKE ANY FUTURE DISASSEMBLY MUCH EASIER..
