Compressor Description
13
Compressors that have a C5 crankshaft drive end
bearing also have a cast iron oil pump housing,
which is painted black. Therefore, a compressor
with a C5 bearing can be identified by the black
oil pump housing as shown in Figure 2.
Compressors that have a pressurized seal cavity
have a “P” on the seal cover. Therefore, a
compressor with a pressurized seal cavity can be
identified by the “P” on the seal cover as shown in
Figure 3.
