Mounting
The shrink discs are supplied ready to be mounted. Therefore they should not be dis-
mantled prior to emploring the unit for the first time.
1. Degrease shaft and hub bore!
2. Slide shrink disc onto hub. The outer surface of the hub may be greased outside
the shrink disc fit.
CAUTION!
Do not tighten the tightening bolts before the shaft is mounted.
3. Fit the shaft or slide the hub onto the shaft.
4. Tighten all tightening bolts uniformly, one by one, over several revolutions until
the outer ring and inner ring are flush. This indicates that the full transmissible
torque is achieved.
5. Check each tightening screw twice for the required tightening torque.
Dismounting
This is similar to mounting.
1. Loosen all tightening bolts, initially not more than a quarter turn per bolt, one
after one.
CAUTION!
Under no circumstances should the locking bolts be completely removed as this
could be dangerous and result in injury.
2. Should the outer ring, when loosening the bolts, not slide automatically from the
inner ring, this can be assisted by removing those locking bolts adjacent to the
tapped bores provided for jacking purposes and screwing them into these. The
