TORQUE ARM II BELT GUARD INSTALLATION:
Two different belt guards are available for the Torque-Arm
II speed reducer. One belt guard assembly is designed for
mounting in position “B” and the other belt guard assembly is
designed for mounting in position “C” as shown in Figure 1. It is
important that the mounting position of the Torque-Arm II Motor
Mount be determined prior to purchase of the belt guard as
these two guards do not interchange and will be attached to the
motor mount uprights.
