Maintenance Schedule and Usage
Guidelines
Regularly scheduled maintenance is the single most
important factor in maintaining the air brake charging
system. The table below is an introduction to the
maintenance intervals for air brake charging systems.
See your compressor and/or air dryer Service Data
sheet for more information.
If you are concerned that a compressor may be
passing oil, use the Bendix

BASIC Test Kit: Order

a. Note: Compressor and/or air dryer upgrades are
recommended in cases where duty cycle is greater than
the normal range (for the examples above). For certain
vehicles/applications, where turbo-charged inlet air is
used, a smaller size compressor may be permissible.
b. To counter above normal temperatures at the air dryer
inlet, (and resultant oil-vapor passing upstream in the air
system) replace the discharge line with one of a larger
diameter and/or longer length. This helps reduce the
temperature of the discharged air. If suffi cient cooling
occurs, the oil-vapor condenses and can be removed by
the air dryer. Discharge line upgrades are not covered
under warranty. Note: To help prevent discharge line
freeze-ups, shorter discharge line lengths or insulation
may be required in cold climates. See Bendix Bulletins
TCH-08-21 and TCH-08-22, for more information.
c. With increased air demand the air dryer cartridge needs
to be replaced more often.
Low Air Us e
e.g. Line haul single
trailer without air
suspension, air over
hydraulic brakes.
High Air Use
e.g. Double/triple trailer,
open highway coach,
(most) pick-up & delivery,
yard or terminal jockey,
off-highway, construction,
loggers, concrete mixer,
dump truck, fi re truck.
Very High Air
Use
e.g. City transit bus,
refuse, bulk unloaders,
low boys, urban region
coach, central tire
infl ation.
