16. Horizontal Alignment: hold compressor assembly
(17) such that when viewed from above both
couplers (8) and flex insert (9) are aligned axially.
When properly aligned, tighten mounting bracket
bolts (12) to frame to 23-27 ft-lbs (31-37 N•m).
Horizontal alignment is now complete.
17. Vertical Alignment: hold compressor assembly (17)
such that from the side both couplers (8) and flex
insert (9) are aligned axially. When properly aligned,
tighten four nuts (19) on studs (16) to mounting
bracket (10) to 150-160 in-lb (16.9-18 N•m).
Vertical alignment is now complete.
18. With the second coupler (8) still loose on coupler
shaft (15), slide coupler (8) against flex insert (9)
until flex insert is tightly sandwiched between both
couplers. Back coupler (8) off approximately 1/16
in., leaving a slight gap between coupler (8) and flex
insert (9). Tighten set screws in loose coupler (8)
with 1/8 in. Allen wrench to 150-160 in-lb (16.9-18
N•m). Verify flex insert (9) can wiggle slightly
between couplers. Only a slight amount of
movement is required.
NOTICE
Performing the following step incorrectly may result in
improper alignment of the two rotating couplers. This
may cause premature wear and require replacement
of the flex insert (9).
