26. Unbraze the hot gas discharge line at the compressor (see Figure 3.8).
27. Remove the compressor by removing the two lock-nuts on the mounting plate of the compressor. Lift the compressor off
of the carriage bolts (see Figure 3.8).
28. Install the four rubber grommets in the bottom of the new compressor and install the two sleeves where the carriage
bolts will be located. Mount the new compressor and install the two washers and lock-nuts and tighten to 4 in-lbs. DO
NOT REMOVE THE RUBBER PLUGS AT THE TUBE STUBS ON THE COMPRESSOR AT THIS TIME.
29. Remove the insulation tube on the evaporator tubing harness.
30. Remove the evaporator from the front of the unit. The evaporator will need to be tilted 90 degrees down and then the
tubing harness with the accumulator will fit through the opening in the liner.
Installing the Evaporator:
Reverse the removal procedure (see above) for installation. Remove the plugs from the compressor right before brazing. Make
certain that the suction line and tubing harness insulation tube are installed and sealed. Also, check the thermistor to make sure it
has full contact and is secure. Be sure to check for leaks, flush the system thoroughly, and evacuate to 50 microns. Weight charge
the system (see Section 2.7, Re-charging).
