Applying Torque to Motor Bolts
WARNING
NEVER REUSE THE MOTOR INSTALLATION HARDWARE (BOLTS, WASHERS, AND
NUTS). ALWAYS USE NEW HARDWARE. CONFIRM TORQUE FOR ALL NEW MOTOR
BOLTS AFTER THE FIRST FOUR HOURS OF OPERATING TIME.
Operators will prolong the life of Shale Shaker motor bolts if torque is properly applied at the appropriate
intervals.
1.
Using a 30mm socket (¾”drive) with a 200mm (8”) extension, apply an initial torque of 160ft-lbs. (217Nm) to
all newly installed motor bolts.
a.
Apply torque to each bolt in the order illustrated in Figure 30.
2.
Apply a final torque of 300ft-lbs. (447.5Nm) to the motor bolts, once more following the torque order from
3.
After four hours of operating time, confirm all motor bolts still have 300ft-lbs. (447.5Nm) of torque applied.
NOTE
THERE ARE A TOTAL OF SIX MOTOR BOLTS ON EACH MOTOR. ALL BOLTS RECEIVE
PROPER TORQUE FROM THE FACTORY.
4.
Verify and document motor bolt torque every 672 hours or once per month of operation.

Electrical Connections (Isolators)
Make sure black neoprene vibration isolators are installed properly prior to operating equipment any time motor
leads are changed or cable is replaced.
CAUTION
WHILE THE ISOLATORS ARE REMOVABLE, THEY SHOULD ALWAYS BE IN PLACE
WHEN THE UNIT IS IN USE TO PROTECT ELECTRICAL CONNECTIONS IN THE
MOTOR. FAILURE TO DO SO CAUSES PREMATURE FAILURE OF THE WIRING AND
COULD ALSO CAUSE THE MOUNTING POSTS TO BREAK.
1.
Remove the four bolts securing the motor lead electrical cover.
2.
Install the thin isolator first (Refer to Figure 31).
