INSTALLATION: DBSS/DBES MODELS (Double C-Face) These models are intended to be concentrically located between two pieces of equipment such as a motor and reducer. They are not intended to have a sheave, pulley, sprocket or any overhung load placed on the output shaft. Note: There are two access holes in the brake housing for tightening the hub set screws. Positioning the hub setscrews in-line with these access holes by releasing the manual release levers and rotating the shaft will make location easier after the brake is positioned onto the motor shaft. STEP 1. Slide brake onto motor shaft taking care first to remove any burrs on the motor shaft. If force seems to be needed for proper mounting, check for other problem areas. DO NOT HAMMER BRAKE INTO PLACE. Once the brake contacts the motor face, rotate the entire brake to align the mounting holes. Finger tighten the mounting bolts to secure the brake to the motor. STEP 2. Tighten the (4) mounting thru bolts ( -16 UNC) to the motor with 300 Ib-in of torque. STEP 3. Using the access holes in the housing, tighten the two setscrews in the splined hub to 75-80 Ib.-in. as shown in picture. The setscrews should be already aligned with the access holes so that no adjustments or movement of the motor shaft or hub are necessary to enable tightening of the setscrews.
