NOTE: With the coupling in good alignment, the bolts
will t through the holes in the anges and the disc
pack more easily. It is recommended that all locknuts
be retightened after several hours of initial operation.
5. For further help with the installation or align-
ment, consult Rexnord.
F. Disc Pack Replacement.
If it becomes necessary to replace the disc pack, it can
be done as follows:
1. Remove all the long bolts and lower the center
ring by sliding it our from between the two disc
packs.
2. Remove one short bolt from the disc pack/hub
connection and reinstall it through a hub clearance
hole and into the hole in the disc pack. Put the nut
on. This will keep the discs together and maintains
the disc orientation for later reinstallation. Remove
the rest of the short bolts and takeoff the disc pack.
Repeat for the second disc pack.
3. Replace the pack(s) if required. Recheck align-
ment per Section D. Reassemble per Section E.
