REFRIGERANT COMPRESSOR OIL CHECK - CONTINUED
Complete Check of Compressor Oil - Continued
5.
Dispose of oil in a suitable container. Use the following list as a guide for adding oil into compressor:
a.
If amount of oil drained from compressor is 6 to 8 fl oz (177 to 237 ml), put same amount of new refrigerant oil in
compressor. Never refill with more than 8 fl oz (237 ml) of oil in compressor unless system has been flushed.
b.
If amount of oil drained from compressor is less than 6 fl oz (177 ml), add 6 to 8 fl oz (177 to 237 ml) of new
refrigerant oil to compressor.
c.
If a new compressor or a rebuilt compressor is installed, drain all oil from compressor and add 6 to 8 fl oz (177 to
237 ml) of new refrigerant oil to compressor.
d.
If system was flushed do not remove oil from a new compressor.
e.
Refer to Table 2 if individual components are replaced without charging compressor or without flushing system.
Table 2. Oil Capacities for Component Replacement.
Accumulator
1 fl oz (30 ml)
Compressor
Refer to Refrigerant Compressor Oil Check in this work
package.
1 fl oz (30 ml)
3 fl oz (90 ml)
Inline Dryer (1)
1 fl oz (30 ml)
Receiver/Dryer
1 fl oz (30 ml)
6.
If failure of a component causes particles of metal or other foreign material to be present in system, it is necessary to
flush system. Refer to Troubleshooting Without a Diagnostic Code (WP 0008 00).
N OT E
If too much oil has been added to system and a total of more than 11 fl oz (325 ml) of oil is in system, cooling
capacity of system will be reduced. If too little oil has been added to system, compressor may fail due to a
lack of lubrication.
Add oil to compressor through opening for oil plug or inject oil through ports for charging. Compressor
must be positioned so refrigerant oil will not flow out of service valves. Do not rest compressor on compres-
sor shaft. Turn compressor shaft by hand when you fill compressor. Oil will slowly flow into compressor.
Only use refrigerant oil approved and recommended.
Add oil to any components being installed.
Inject oil into pressurized system through port for low pressure charging while engine is running and com-
pressor is operating.
7.
After correct amount of refrigerant oil has been added to system, install compressor and drive belt (WP 0192 00).
