Servis-Rhino 2160 Motor & Coupling Installation, Taper Bushing & Sheave Installation, Maintenance

MAINTENANCE

MOTOR & COUPLING INSTALLATION

Bolt motor to mount plate. Fully tighten bolts. (Item 1). Install flex coupler to the quick disconnect pulley hub using the countersunk socket head bolts (Item 2). Apply thread locking compound to the bolts. Tighten bolts to 45 FT-LB. Attach motor mount angle brackets, (Item 3) to the channel frame, leave bolts loose.

Insert motor shaft into flex coupling and allow motor to “find its center”.

Adjust motor up as needed to provide ample clearance between the top of flex coupling and the motor. Bring angle brackets up to motor mount plate and tighten the bolts.

TAPER BUSHING & SHEAVE

INSTALLATION

Do not use lubricants during installation as this may cause sheave breakage.

Make sure the bushing and bore of the sheave are free of dirt, paint, metal chips, etc. Insert cap screws and lockwashers engaging only 2 or 3 threads.

With key in the keyway, slide the loosely assembled unit onto the shaft and position for good belt alignment. Temporary shimming under the pulley may make it easier to position.

Carefully tighten cap screws alternately and progressively until tapers are seated (about 5 FT-LB). Check sheave alignment and runout (wobble).

Continue careful alternate and progressive tightening of cap screws to 10 FT-LB. Maximum torque should be achieved on each individual bolt only two times.
