COUPLINGS INSTALLATION
AND ALIGNMENT
These instructions are intended to help you to
installand align the coupling. Covered here will
be general information, hub mounting, alignment,
assembly, locknut torquing, discpack replacement,
and part numbers. The coupling as received, may
or may not be assembled.
*If assembled, the locknuts are not torqued.
*If coupling is assembled, remove the bolts that
attach the hubs to the disc packs. Remove both
hubs. Leave the disc packs attached to the center
member.
A. Hub Mounting:
1. Clean hub bores and shafts. Remove any
nicks or burrs. If bore is tapered, check for good
contact pattern. If the bore is straight, mea-
sure the bore and shaft diameters to assure
proper fit. The key(s) should have a snug side-
to-side fit with a small clearance over the top.
NOTE: If the DBZ hub position on the shaft does
not allow enough room to install the short bolts
in the hub after hub mounting, install the bolts
and disc pack before mounting hub on shaft.
B. Straight Bore:
1. Install key(s) in the shaft. If the hub is an
interference fit, heat the hub in an oil bath or
oven until bore is sufficiently larger than the
shaft. 350º F. is usually sufficient. An open
flame is not recommended. However, if flame
heating is necessary, use a very large rose bud
tip to give even heat distribution. A thermal
heat stick will help determine hub tempera-
ture.
DO NOT SPOT HEAT THE HUB OR
DISTORTION MAY OCCUR.
With the hubs
expanded, slide it up the shaft to the desired
axial position. A pre-set axial stop device can
be helpful.
NOTE: All DBZ hubs have pressed in bushings.
Make sure the bushings are facing the disc pack.
C. Taper Bore:
1. Put the hub on the shaft without key(s)
inplace. Lightly tap hub up the shaft with a
soft hammer. This will assure a metal-to-metal
fit between shaft and hub. This is the starting
point for the axial draw. Record this position
