Oil Collection Container
The oil collection container was added to trailer
units starting in the first quarter of 2010. The oil
collection container collects the compressor shaft
seal seepage to keep the unit clean. This seepage
is normal and is necessary for shaft seal durability.
The oil collection container is mounted on the
body of the compressor. A tube connects the oil
collection container to the compressor shaft seal
cover. The oil that seeps from the seal will travel
through the tube and collect in the container.
Empty the container once per year during oil
changes, or during annual services. The container
has a drain spout with a cap. Remove cap and
drain the oil into a cup (not provided) and discard
the oil properly. Retighten the cap snugly by hand.
NOTE: The oil collection bottle is not used in
Europe.
The check valve was added in November 2012 to
improve the shaft seal reliability by ensuring oil
stays on the shaft seal when the suction pressure is
in a vacuum. It is made of silicone rubber, a
material that can be damaged easily. The check
valve is located on the end of the tube inside the
container. It is a very tight fit between the check
valve and the grommet in the oil collection
container.
NOTE: The check valve is no longer required on
Pressurized Seal Cavity Compressors.
If maintenance in the area requires removal of the
oil collection container or the tube, caution should
be observed to prevent damage to the check valve.
Although the check valve was glued to the tube at
production, pulling the check valve back through
the grommet may cause the Valve to fall off or be
damaged.
Several options are available:
1. If possible, disconnect the tube at the seal
cover drain barb and leave the tube in the oil
collection container.
2. The grommet can be pried off the bottle with
the tube still inserted, allowing the tube and
check valve to be easily removed from the
container.
