Replacing the pulley
1.
The pulleys are mounted on the shaft with a taper lock
constructed of a two-part conical bushing (taper lock)
which holds the pulley in place and makes it possible to
adjust the wheel on the side of the shaft at the same time
.
The taper lock is held together by 6 or 8 bolts
(depending on the model). The bushing also has 3
or 4 holes which are empty.
Unscrewing all bolts and screwing them into the
empty holes instead, forces the conical outer
section out of the taper lock, thus releasing the
pulley from the shaft.
2.
Similarly, it is also possible to adjust and tighten the
pulley on the side of the shaft using the taper lock
so that the V-belts run as straight and smoothly on
the pulley as possible. If they do not do this the V-
belts will wear out and ultimately break.
3.
Once the V-belt is running straight and smoothly on
the pulley, reattach all nuts in parallel and stepwise to
lock the taper lock, and thus the pulley, to the shaft.
Make sure that the V-belt still operates correctly.
To tighten the taper lock, gradually tighten the bolts, moving to each bolt in a circular
fashion, doing this several times, until all of the bolts are tightened.
