Installation of Optibelt pulley with taper bush

INSTALLATION:
1. All shiny surfaces such as bore and end envelope of cone of the taper bush as well as conical bore of the pulley should be clean and free of grease. Fit the taper bush into the hub and align with all holes. The half-tapped holes should be aligned with the half plain bored holes.
2. Lightly oil the stud screws (TB 1008-3030) and/or fillister socket screws (TB 3525-5050) and screw them in. Do not yet tighten screws.
3. Clean and degrease the shaft. Position the pulley with the taper bush in the correct place on the shaft. See information about V-grooved pulley alignment.
4. If a key is used, place this first into the keyway of the shaft. Make sure there is a tolerance between the key and the bore keyway.
5. Using a socket wrench according to DIN 911, tighten the stud screws or the fillister socket screws evenly to the torque values given in the table.
6. After a short run (0.5 to 1 hour), check the tightening torque values of the screws and tighten if necessary.
7. Fill the empty bush bores with grease to prevent foreign matter from entering.
REMOVAL:
1. Loosen all screws. According to bush size, completely unscrew one or two screws, grease them and screw them into the proof test bores.
2. Tighten the screw or screws evenly until the bush comes out of the hub and the pulley can move freely on the shaft.
3. Remove pulley with bush from the shaft.
