11. Inspect the compressor side of the coupling to make
sure some Loctite is present at the joint. If not, apply a
light coating of Loctite to prevent moisture from wick-
ing into the joint and causing corrosion. It may also be
beneficial to cover the exposed part of the crankshaft
with some type of corrosion protection such as paint.
CONDENSER COIL
Removal
1. Remove the refrigerant charge.
2. Open the roadside condenser fan grille.
3. Drain engine coolant from the expansion tank. Unbolt
and remove the coolant expansion tank from the con-
denser coil frame. Unsolder the tank breather tube.

5. Unsolder the inlet line and liquid line connections. Lift
the coil from the unit.
Installation
1. Clean the fittings for soldering.
2. Place the coil in the unit and install the mounting bolts.

4. Pressurize the refrigeration system and test for leaks. If
no leaks are found, evacuate the system.
5. Install the clamps on the condenser inlet line.
6. Install the engine coolant expansion tank and refill half
way with engine coolant.
7. Close hinged roadside condenser fan grille.
8. Recharge the unit with proper refrigerant and check the
compressor oil.
DISCHARGE VIBRASORBER
Removal
1. Remove the refrigerant charge.
2. Heat the connections on the vibrasorber until the vibra-
sorber can be removed.
CAUTION: Use a heat sink, P/N 204-584 or
wrap the vibrasorber with wet rags to prevent
damaging the vibrasorber.
Installation
1. Prepare the vibrasorber and tubing fittings by cleaning
thoroughly.
2. Solder the vibrasorber connections.
