Check pulley alignment
After replacing and tensioning the belts or pulleys, it is necessary to
check the alignment of the pulleys (use a metal ruler or other suitable
alignment measuring equipment, see figure 24). Specifications of limit
values are included in table 7.

Misalignment type
Angular
Parallel
The following applies:
Parallel:
Maximum misalignment of parallel planes: 0.01 x axis distance (i.e., max.
10 mm at axis distance of 1 m)
Angular:
Misalignment of the pulley from the plane: 0.25° for each meter of
distance (i.e., max. 0.5° at axis distance of 2 m)
The pulleys are equipped with Taper-Lock collets which enable their
alignment (see figure # 25). The torque values for the set screws on the
clamping hubs are included in table 6.

Before collet and pulley assembly, carefully clean
the inner collet opening and taper surface.
Insert the collet into the pulley hub so that the
threaded openings will check with the openings
without thread.
Tighten the fixing screws by hand.
Carefully clean the shaft, and place the pulley in the
required position. Tighten the fixing screws alter-
nately with the prescribed tightening torque.
Loosen the fixing screws, and insert one or two of
them as force-off screws (according to the collet
size) into the withdrawal openings. Knock slightly
on the pulley. Keep tightening the force-off screws
until the collet is released from the pulley.
