MOTOR MOUNTING
The following procedure is required only when the motor is
mounted at the job site.
1. Thoroughly clean the motor feet and mounting pads of
grease, burrs, and other foreign matter to ensure fi rm seat-
ing of the motor.
2. Attach the motor to the base using the bolts and motor-
raising blocks, if required. Bolt snugly through the base.
3. Weld the four kick bolts into place so that they are po si -
tioned to allow movement of the motor feet.
4. Now that the motor has been set, check to see that the
shafts are properly spaced for the coupling being used. Re-
fer to the coupling data tables for the applicable di men sion
(pag es 5 and 6).
CHECKING MOTOR/COMPRESS OR ROTA TION
Make sure coupling hubs are tight-
ened to the shaft be fore rotating the
motor to prevent them from fl ying
off and possibly caus ing serious injury or death.

COMPRESSOR/MOTOR COUPLINGS
INSTALLATION
RWB II units are arranged for direct motor drive and require
a fl exible drive cou pling to connect the com pres sor to the
motor. Before installing, perform the following:
1. Inspect the shaft of the motor and compressor to ensure
that no nicks, grease, or foreign matter is present.
2. Inspect the bores in the coupling hubs to make sure that
they are free of burrs, dirt, and grit.
CH COUPLING DATA TABLE
3. Check that the keys fi t the hubs and shafts properly.
CH COUPLING – The T.B. Woods Elastomeric CH Cou pling
is used in most applications up to 600 HP. It consists of two
drive hubs and a loose, gear-type Hytrel Drive Spac er. The
split hub is clamped to the shaft by tight en ing the clamp
screws. Torque is trans mit ted from the mo tor through the
elas to mer ic gear which fl oats freely be tween the hubs. In stall
as fol lows:
1. Slide one hub onto each shaft as far as possible. It may
be nec es sary to use a screwdriver as a wedge in the slot to
open the bore before the hubs will slide on the shafts.
2. Hold the elastomeric gear between the hubs and slide both
hubs onto the gear to fully engage the mating teeth. Center
the gear and hub assembly so there is equal en gage ment
on both shafts. Adjust the space between hubs as specifi ed
in the CH Coupling Data Table below.
3. Torque the clamping bolts in both hubs to the torque val ue
given in the CH Data Table. DO NOT USE ANY LU BRI CANT
ON THESE BOLTS.
4. Proceed to Coupling Alignment.
DBZ-B COUPLING – The Thomas DBZ-B coupling is used
on ap pli ca tions above 600 HP and with sleeve bear ing mo-
tors that do not have ax i al end fl oat con straint. The DBZ-B
cou pling con sists of two drive hubs and a fl ex i ble met al disc
drive spacer that is bolt ed to both hubs. A fl exible steel disc
pack serves as the drive element. This disc pack is bolted to
the cou pling hubs and prevents axial end fl oat between the
com pres sor and motor shafts which may oc cur with sleeve
bear ing motors. On sleeve bearing mo tors, the magnetic
center must be de ter mined and main tained by se cur ing the
cou pling to the mo tor shaft with the shaft properly lo cat ed.
Injury may occur if loose clothing,
etc. be comes entan gled on the
spin ning mo tor shaft.
If the motor is coupled to the com pres sor using a fi xed-end-
play cou pling, such as a DBZ-B coupling, and the motor is not
prop er ly centered, ad di tion al thrust loads will be trans mit ted
to the compres sor bear ings that could re sult in pre ma ture
bear ing failure. In stall as fol lows:
1. Remove the eight locknuts and long bolts attaching the
center member to the disc pack.
2. Slide the disc pack and coupling hub assemblies on their
re spec tive shafts.
