Replacement of pulley
1.
The pulleys are mounted on the shaft with a taper
lock constructed of a two-part conical bushing 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 taper lock 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 don’t, 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 around in a ring several times
until all bolts are tightened.
