Compressor Inlet Bearing Oil Orifice — The oil
line leading to the compressor lubrication block is connected to
the inlet bearing oil orifice. The orifice is pressed into a
standard reducer/expander fitting and protected by a 50 x 50
mesh screen (see Fig. 57). Compressor oil lines and fittings be-
tween the oil filter and compressor must be capped during dis-
assembly to prevent contamination. Inspect the inlet bearing oil
orifice whenever the oil line between the oil filter and compres-
sor is disconnected.
Inspect Condenser Refrigerant Float System
(Frame 3-5 Heat Exchangers) — Perform this in-
spection when the condenser is opened for service. See Fig. 58.
1. Transfer the refrigerant into the cooler vessel or into a
pumpout storage tank.
2. Remove the float access cover.
3. Clean the chamber and valve assembly thoroughly. Be
sure the valve moves freely. Ensure that all openings are
free of obstructions.
4. Apply thread locking adhesive (P/N 24221 [10 ml] or
24231 [50 ml]) the

-in. - 16 bolts that hold the float
valve in place. See Fig. 58 for a view of the float valve
design. Inspect the orientation of the float slide pin. It
must be pointed toward the bubbler tube for proper
operation.
5. Apply gasket sealant (P/N 19XL680-002) to both sides of
new gasket when reinstalling cover.
