half so that it reads from the face of the motor cou-
pling half.
2) Position the indicator on the side of the coupling.
3) Rotate the coupling halves together, 180° in the
direction of the compressor rotation. The indica-
tor reading in this position is the amount of angular
misalignment.
4) Loosen the motor mounting bolts and move the mo-
tor slightly with a pry bar or soft mallet so that when
step C is performed, the indicator reading is within
machine specification.
NOTICE!
Do not lubricate capscrew threads. If capscrews
are used, apply thread-locking adhesive. These
are special bolts. Do not substitute.

motor coupling half.
2) Position the indicator on the side of the coupling.
3) Rotate the coupling halves together, 180° in the
direction of the compressor rotation. The indica-
tor reading in this position is the amount of parallel
misalignment.
4) Loosen the motor mounting bolts and move the mo-
tor slightly with a pry bar or soft mallet so that when
step C is performed, the indicator reading is within
machine specifications.
NOTICE!
Always recheck all measurements since one align-
ment procedure may effect another.
Reinstall the other coupling half and torque all
mounting bolts. Before placing the unit in opera-
tion, replace the drive guard and clear the area
of all tools.
