12.10 Mounting and dismounting the taper-lock clamping bush
Carry out the following instructions for the correct mounting and dismounting of the taper-lock
clamping bush (see Figure 19
Figure 19
Mounting:
1. Thoroughly clean the clamping bush / pulley and axle, so that grease and other dirt
are removed from them.
2. Place the clamping bush in the pulley in the correct position. The three holes (1 + 2) of
the clamping bush must be aligned with the holes of the pulley.
3. Apply oil to the socket-screws, insert them into the holes (1) and screw them hand-
tight.
4. Place the pulley including the clamping bush over the axle and position in the required
position.
5. Tighten both socket-screws evenly until the corresponding tightening moment is
achieved.
6. Using a hammer and a wooden chock or adaptor ring, beat the outermost ring surface
(3) of the clamping bush to settle the ring.
Tighten the socket-screws again, until the corresponding tightening moment is achieved.
Repeat this once or twice.
7. Let the machine run for approx. one (1) hour and check whether the moment of the
socket-screws has not deviated. If this is the case, tighten the socket-screw(s) until
the corresponding tightening moment is achieved and repeat the procedure.
Clamping bush Tightening moment
1008/ 1108 6 Nm (4.4lbf/ft)
1210/ 1215/ 1310/ 1315/ 1610/ 1615 20 Nm (14.8 lbf.ft)
2012 30 Nm (22.1 lbf.ft)
2517 50 Nm (36.9 lbf.ft)
3020/ 3030 90 Nm (66.4 lbf.ft)
3535 115 Nm (84.8 lbf.ft)
Dismounting:
1. Remove the socket-screws from position 1.
2. Apply oil to one socket-screw and place it in position 2.
3. Tighten the socket-screw up to the point that the clamping bush comes loose from the
pulley. Remove both parts from the axle.
