Follow these steps to attach the customer supplied mounting bracket .
• Place rubber bushing and mounting angle bracket on bolt .
• Verify that the mounting angle bracket hole is the correct diameter (see Table 13
in Step 1) .
• Place remaining bushing, washer and two nuts on the bolt .
Do not
over-tighten nuts . Tighten to point where rubber bushings can
still be hand rotated .
4
Confirm that the rubber bushings can still be rotated by hand . This indicates the
bushing has not been over tightened .
Compressed bushings will not allow the bushings to properly absorb the
loads of the shaft mounted gearbox . This can lead to premature failure .
Mounting Angle Bracket must be secured to the machine structure .
5
Confirm the mounting angle bracket
does not interfere with the torque arm .
There should be no metal-to-metal contact between the two during a complete
revolution of the driven equipment .
Metal-to-Metal contact between these two components may lead to
catastrophic failure of the reducer/gearmotor .
