Installation Instructions for 6P-A1C six bolt Composite
Disc Couplings

1. Tools Required:

 Torque wrench with hex sockets for clamp hub

socket head cap screws.

 Laser alignment tool or dial indicator

(recommended). If not available a straight edge
and feeler gauges.

 Caliper

2. These instructions are for standard series couplings
with normal running conditions. Special couplings may
have different instructions or drawings.

3. When initially mounting the coupling, the
misalignment may be one and one half times the
maximum permissible misalignment shown in the
catalog. Inspect hub bores, shafts, and keyways
making sure there are no burrs. Clean hub bores and
shafts. Standard CD coupling hubs are supplied with
slight clearance fit (see catalog).

.

4. Install the coupling onto the shafts. It is recommended
that the ends of both shafts be flush with the end of each
hub. At the minimum each shaft should extend past the
hub clamp slot and extend into one third of the hub
flange (non-slotted) area. If the shaft extends past the
hub face verify there is enough clearance between shaft
and disc pack and the shaft will not contact the disc pack
during operation. Tighten one clamp hub socket head cap
screw to lock the hub onto the shaft. See the table for the
proper tightening torque.

5. Adjust hub separation to dimension “C” specified in the

Table and diagram. Tighten Second hub to the shaft.

6. Align the shafts within the limits for parallel and
angular misalignment specified on page two. For best
alignment results, use a laser alignment tool or dial
indicator.

Note: Aligning the shafts as closely as possible at the time
of initial installation will reduce noise and allow the
coupling extra capacity for misalignments and loads which
will occur during operation over the life of the connected
equipment. Installing and operating coupling at higher
degrees of misalignment is possible (see catalog ratings),
but will generally reduce the life of the composite disc
pack.

Coupling and shaft alignment should be checked
periodically due to foundation settling, equipment
shifting, etc. Alignment should be re-checked after the
first several hours of operation.

Caution: Rotating equipment is potentially

dangerous and should be properly guarded. It is the
responsibility of the machine builder, user, or operator
to follow all applicable safety codes and provide a

suitable guard. Make sure the machine is “locked out”

and cannot be accidently started during installation or
maintenance of coupling.
