FACE  MOUNTING

Face mounting holes are not drilled on standard units -- Contact factory if face mounting is desired.

TORQUE ARM

The preferred position for the torque arm is 90° to a line between the point of attachment of the torque arm to the drive and the low speed shaft. The torque arm must be in tension. Keep the torque plate in the position shown.

EXTERNAL  BACKSTOP  KIT

Backstop extensions are standard on double reduction drives and can be supplied on single reduction drives if specified when order is placed. See Engineering Information section for backstop torque capacity.
