A-8
Symptom:
What it may indicate:
What you should do:
(i) Poorly filtered inlet air (poor air
quality to compressor).
(j) Governor malfunction or setting.
(k) Compressor malfunction.
4.0 Oil in Supply
or Service
Reservoir*
(air dryer installed)
(continued)
Check for leaking, damaged or defective
compressor air inlet components (e.g.
induction line, fi ttings, gaskets, fi lter bodies,
etc.). Repair inlet components as needed.
Note: Dirt ingestion will damage compressor
and is not covered under warranty.
Go to Test 4 on page A-15.
If you found excessive oil present in the
service reservoir in step 4.0 (b) above and
you did not fi nd any issues in steps 4.0 (c)
through 4.0 (j) above, the compressor may
be passing oil.
Replace compressor. If still under warranty,
follow normal warranty process. Note: After
replacing a compressor, residual oil may
take a considerable period of time to be
fl ushed from the air brake system.
Other (cont.)
Inspect the
engine air
cleaner.
** SAE J2024 outlines tests all air brake system pneumatic
components need to be able to pass, including minimum
levels of tolerance to contamination.
5.0 Oil present
at valves (e.g. at
exhaust, or seen
during servicing).
Air brake system valves are required
to tolerate a light coating of oil.
A small amount of oil does not affect SAE
J2024** compliant valves.
Check that regular maintenance is being
performed and that the amount of oil in the
air tanks (reservoirs) is within the accept-
able range shown on the Bendix

test cup (see also column 5 of Table A on
page A-3). Return the vehicle to service.

Crankcase Flooding
Consider installing a compressor bottom drain kit
(where available) in cases of chronic oil passing where
all other operating conditions have been investigated.
Bendix compressors are designed to have a 'dry'
sump and the presence of excess oil in the crankcase
can lead to oil carryover.
