compressor hub and shrink disc assembly onto
compressor hub. Shaft should be recessed 3/8”
from face of hub. Gradually tighten all shrink disc
locking screws to 42 ft. lbs. torque per step no. 6,
(under INSTALLATION SEQUENCE), and
STEP 2 OFFSET ALIGNMENT
- Position equip-
ment for coupling gap approximately 7” (178mm).
Align the shafts so that a straight edge will rest
squarely (or within the offset limits specified in
) on both flanges and at a point
90º away. Vertical offset alignment is adjusted by
the addition or removal of motor mounting shims.
Loosen motor mounting bolts and slide the motor
sideways to correct the horizontal offset.
STEP 3 COUPLING GAP AND ANGULAR ALIGN-
MENT
- Align shafts within the angular limits and to
. To determine angular misalignment in inches,
measure the maximum space between flanges and
the minimum space 180º away, then subtract. To
adjust the motor mounting bolts and adjust the
motor position until the angular alignment is within
tolerance.
DO NOT upset the offset alignment or hub gap
when adjusting motor position.
Tighten the spacer mounting bolts and recheck off-
set and angular alignment (within the limits speci-
fied in
angular alignment is not within the specified toler-
ance, shim the front or rear of the motor separately
to correct. Recheck the vertical offset.
COUPLING ELEMENT INSTALLATION
1. Insert installation/removal bolts provided through
clearance holes in spacer and into tapped holes
in adapters. A quantity of six (6) 5/16-18 UNC x
1 1/2” long bolts are required. Assemble all fas-
teners to a “finger tight” condition. Then tighten
each fastener in both flanges an additional 1 1/2
turns from the finger tight position. This will draw
the adapters toward the spacer and allow the
spacer assembly to clear the registers on the
