Rotate the Tension Block (CW) back into position
and reinstall 5/16-18 SHCS through the back side of
the Mounting Plate using a 1/4” allen wrench.
The Tension Block is not to be used for tensioning the belt. The purpose of the Tension
Block is to help control the Tension Arm “backlash” on motors with high starting torque.
NOTE:
Using a flat blade screwdriver, adjust the
slotted 5/16-18 SS Hex Head screw on
the Tension Block until the Hex Head
just touches the Rubber Block on the
Tension Arm assembly. Tighten jam nut
with a 1/4” wrench and reinstall the belt
guard cover.
The hex head screw is not designed to put additional pressure on the Tension Arm or Belt, it is intended to pre-
vent the backward movement of high torque motors.
NOTES:
The same belt removal and installation procedure applies for the RB2400 Model with one exception– there are
two (2) belts.
