the Touchdown Bearing/Labyrinth Seal Plate jacking screw locations. Tighten them evenly in a

the compressor housing.
The Shaft of the Compressor will now be sitting directly on the front bearing. Do not try to move the
shaft around or damage may occur to the shaft or front bearing.
Label the shims for order and orientation! Failure to maintain the order of the shims could result in
operability problems and in some cases, damage to internal components.
