NNoottee:: Plan ahead where the compressor will be
secured. Build a suitable plant form to support
the assembly before the lift. Gently set
compressor onto prefabricated pre-formatted
support. Use care not to damage the cast
compressor foot (see foot in Figure 8, p. 22).
Similarly, avoid damage to the discharge volute
flange (see discharge flange in Figure 9, p. 22).
8. Remove the compressor/motor assembly. Remove
the locating dowel pins from the compressor foot
and discharge flange connections as shown in
Figure 8, p. 22 and Figure 9, p. 22. To remove the
dowel pin, first remove the nut on the dowel pin,
place a bushing on the pin, and then reinstall the
nut. As the nut is tightened, the dowel pin should
pull out of its hole; at this point, remove the
compressor/motor assembly.
Compressor Motor Mount
Disassembly
If additional vertical clearance is required, the height of
the compressor motor mount can be reduced. Use the
following procedure:
1. Before cutting off the motor mount, first fabricate a
1/4-inch steel backing plate.
a. Cut the backing plate to shape and clamp it to
the motor mount.
b. Drill four 1/4-inch holes through the motor
mount and the backing plate as shown in Figure
16, p. 25. These holes with bolts or roll pins
installed will be used to align the components
during reassembly.
c. Remove the backing plate.
2. Using an oxyacetylene torch, cut the mount as
shown in Figure 16, p. 25.
During reassembly, use the backing plate with bolts or
roll pins to locate the pieces properly. After the pieces
are located, Trane recommends welding the mount and
backing plate in place.

movable floor jack. Do not lift the economizer;
simply support it. Economizer weights are provided
in Table 10, p. 18; also see submittal. It is
