8. Hold horizontal tap bolt nut [
H
] in place with a
wrench while tightening the horizontal tap
bolt [
F
] to secure the motor bracket in place.

necessary until proper tightness is achieved.
Check the belt tension routinely, as new belts
may need to undergo a breaking-in period of
adjustment.
6.4.10 DRIVE SHEAVE (PULLEY) ALIGNMENT
To access the package for drive belt maintenance,
the drive assembly access panel must be removed.
Consult
Section 6.4.1.2, Removing and Replacing
a Side Panel
to remove the drive assembly access
side panel.
Refer to
Figures 6-14
through
6-16
, and the follow-
ing procedure:
Pulley alignment is set at factory and should not
need to be adjusted. If it becomes necessary to
adjust the pulley alignment, an alignment test may be
performed with a straight edge, such as a yard stick,
that is long enough to overlap both the compressor
and motor drive sheaves. Adjustments are made via
positioning of the hydraulic motor (bracket).
Note
that the compressor pulley always remains sta-
tionary during adjustment.
