Compressor Sump Sizes
Units built before mid-February 2003 are
equipped with compressors that have a 4-quart
sump.
Units built after mid-February 2003 are equipped
with compressors that have a 7-quart sump.
Identification
The 4-quart sump measures 2.67 in. (68 mm)
from the bottom of the sump to the top of its
gasket surface.
The 7-quart sump measures 5.35 in. (136 mm)
from the bottom of the sump to the top of its
gasket surface.
Compressor Oil Level
The recommended compressor oil level is the
same for both compressors. The sight glass should
be 1/4 to 1/2 full. See “Checking Compressor Oil”
on page 74. See the Specifications Chapter for the
total quantity of compressor oil.
Compatibility
The 7-quart sump compressor and the 4-quart
sump compressor are interchangeable. However,
the increased oil capacity of the 7-quart sump
improves long-term reliability.
