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 - 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 fit
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, finish assembly be bolting the
motor to the reducer flange. This procedure should insure that the key does not slide back in the
motor keyseat. See FIGURE 9.
MOTOR
SHAFT
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.
2. VENTILATION - During normal operation gear reducers build up heat and pressure that MUST be vented
to protect the seals and gears. If not installed at Titan, a brass vent plug contained in a small plastic bag,
will be put in a box or larger bag along with fasteners sent loose for use during field installation. Remove
the top most drain plug (refer to FIGURE 10) for the position of your reducer) and install the vent plug
securely in place.
3. CLEANING - After approximately two to three weeks of operation the reducer MUST be drained, flushed
out, and refilled to the proper level with fresh oil. (This is done to remove brass particles caused during
the normal wear-in period of the worm gear.) Afterwards, the oil should be changed in your reducer every
2500 hours or ever 6 months, which ever occurs first.

SHAFT
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 SHAFT
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.
