Footnote 1:

 Note: Typical air dryer cartridge replacement schedule is every 3 yrs/ 300K miles for low air use vehicles and every year/100K miles for 

high air use vehicles.

Footnote 2:

 To get an accurate reading for the amount of oil collected during a 30 day period, ask the customer not to drain the air tanks before returning.  

(Note that 30-90 days is the recommended air tank drain schedule for vehicles equipped with a Bendix air dryer that are properly maintained.)  If, in cold 
weather conditions, the 30 day air tank drain schedule is longer than the customer's usual draining interval, the customer must determine, based on its 
experience with the vehicle, whether to participate now, or wait for warmer weather.  See the cold weather tips in Bulletins TCH-008-21 and TCH-008-22 
(included in Appendix B of the advanced troubleshooting guide).

Note for returning vehicles that are being 
re tested after a water/cloudy emulsion 
mixture was found last time and the air 
dryer cartridge replaced:

  If more than one 

oil unit of water or a cloudy emulsion mixture 
is found 

again,

 stop the BASIC

 test and 

consult the air dryer's Service Data sheet 
troubleshooting section.

 mean that 

the compressor must be 
replaced.

Checklist for Technician

The Service Writer fi lls out these fi elds with information gained from the customer

The Service Writer 
also checks off any 
complaints that the 
customer makes to 
help the Technician 
in investigating.

The Technician 
checks boxes 
for any of the 
complaints that 
can be confi rmed.

STEP A 

- Select one:

BASIC

 test starts here:

STEP B 

- Measure the Charging System Contents 

The Technician selects the air use 
category for the vehicle.  This decides 
which of the two acceptance lines on 
the cup will be used for the test below.

For an accurate test, the 
contents of all the air tanks on 
the vehicle should be used.

Then go to Step B.

 Number of Days Since Air Tanks Were Last Drained: ________  Date: ___________Vehicle #: ____________

Engine SN __________________________ Vehicle Used for: _______________Typical Load:________ (lbs.)

No.  of Axles: ____ (tractor) ____ (trailer)  No.  of Lift  Axles: ____  Technician’s Name: ____________________

This is a low air use vehicle: Line haul (single trailer) with 5 or less axles, 

or 

This is a high air use vehicle: Garbage truck, transit bus, bulk unloader, or line 
haul with more than 5 axles.  

1. 

Park and chock vehicle on level ground.  Drain the air system by 
pumping the service brakes.  

2. 

Completely drain 

ALL

 the air tanks into a single 

BASIC

cup.

3. 

If there is less than one unit of contents total, end the test now and 
return the vehicle to service.  Vehicle passes.

4.  

 

If  

more than one oil unit of water (or a cloudy emulsion mixture) 

is found:

Otherwise, 

 go to Step C.
