Assembly sequence
1. Remove any transport securing devices.
2. Loosen but do not remove tightening bolt and tighten gently by hand until there is no play between
the flanges and the inner ring.
3. Slide the shrink disc onto the hollow shaft until the outer clamping flange is flush with the hollow
shaft. The shrink disc is easier to slide on if the bore of the inner ring is lightly greased.
4. Prior to mounting, grease the solid shaft only in the area which will later come into contact with the
bronze bush in the hollow shaft of the gear unit. Do not grease the bronze bush, in order to prevent
grease penetrating the area around the shrink connection.
5. The hollow shaft of the gear unit must be completely de-greased and completely free of grease.
6. In the area of the shrink connection the solid shaft of the machine must be degreased and
completely free of grease.
7. Insert the solid shaft of the machine into the hollow shaft so as to completely fill the area around
the shrink connection.
8. Position the clamping flange by gently tightening the bolts.
9. Tighten the tensioning bolts successively in a clockwise direction by several turns – not crosswise
– with approx. ¼ rotation per turn. Tighten the bolts with a torque wrench to the torque indicated on
the shrink disc.
10. When the tensioning bolts have been tightened, there must be an even gap between the clamping
flanges. If this is not the case, the gear unit must be dismantled and the shrink disc connection
checked for correct fit.
Dismantling sequence:
1. Loosen the tensioning bolts successively in a clockwise direction by several turns with approx. ¼
rotation per turn. Do not remove the bolts from their thread.
2. Loosen the clamping flanges from the cone of the inner ring.
3. Remove the gear unit from the solid shaft of the machine.
If a shrink disk has been in use for a long period or is dirty, it must be dismantled, cleaned and the
conical surfaces coated with Molykote G Rapid Plus or a similar lubricant before it is refitted. The
threads and head surfaces of the screws must be treated with grease without Molykote. Any damaged
or corroded elements must be replaced.
