Subject:

The Bendix AD-2 Air Dryer is a part of a voluntary recall campaign.

What You Need To Do
All vehicle manufactures, dealers and distributors should stop selling any AD-2 air dryer that
was manufactured between November 7, 2001 and May 28, 2002. Please make your customers
aware of the recall campaign.

The Problem
Bendix has determined that the affected air dryer canisters could crack, causing the metal end
plate to become dislodged and expelled with high force which could potentially cause personal
injury to persons outside the vehicle or become a hazardous projectile during vehicle operation.

The Cause
The cause of this condition is due to a change in the material used to manufacture the air dryer canisters during
this period. The material specification has since been revised to prevent recurrence of this fault.

Impacted Product
Impacted AD-2 air dryers, manufactured between November 7, 2001 and May 28,
2002, can be identified by the presence of the date codes stamped on the metal tag
attached to the surface of the dryer metal end plate. See “How to Identify Affected
AD-2 Dryers” as well as the illustration shown here.

How to Identify Affected AD-2 Air Dryers
Impacted dryers, manufactured between November 7, 2001 and May 28, 2002 can be
identified by the presence of one of these 6 or 7 character date codes stamped on a
metal tag attached to the end plate: L_ _ 01_ through E_ _ 02 _ or _ L _ _ 01 _
through _ E _ _ 02 _. The “_” within a date code represents an alphanumeric
character as follows:

AD-2

Date code
located on
side cover
and/or on
metal tag

• If the date code has 7 characters, the first would be a number representing the factory build shift (“2” =

second shift).

• Next is a letter representing the month of manufacture (“A” = January through “M” = December.). The letter

“I” is not used.

• Next are two numbers that represent the day of the month (“01 – 31”).

• These are followed by two additional numbers representing the year (“01” = 2001 and “02” = 2002).

• Last is a letter that represents the location of the manufacturing plant.

For example, a date code may appear as something similar to the following: L0701H or 2E2802H. The date code
L0701H indicates the product was manufactured on November 7, 2001 at the Bendix facility in Huntington,
Indiana. The date code 2E2802H indicates the product was manufactured during second shift on May 28, 2002 at
Huntington.

AD-2 air dryers with any other date codes outside the November 7, 2001 to May 28, 2002 timeframe are not
included in this recall campaign. If no date code tag is present, or the tag is not readable, please contact the
Bendix Tech Team for further information to identify the affected units. To reach the Bendix Tech Team call 1-

unused air dryers to Bendix for a no cost exchange. Please call Bendix Customer Service 1-800-247-2725 and

Air Dryer Repair

WARNING - ALWAYS REPLACE END COVER CLAMP IF REMOVED FOR SERVICING

If you are a lessor of vehicles which are equipped with affected AD-2 air dryers, Federal law requires that any
vehicle lessor receiving the recall notice must forward a copy of the notice to the lessee within ten days.

The end cover clamp must remain on the air dryer, in the proper position, for the life of the AD-2 dryer during
any operation or pressurization of the dryer. The end cover clamp may be removed only to allow access to the air
dryer interior for servicing, such as replacing the air dryer cartridge. Ensure all reservoirs are drained and all
pressure from the air dryer is relieved before removing the end cover clamp. After servicing reinstall the end
cover clamp. Note the clamp is not a substitute for the end cover snap ring. Both the end cover snap ring and the
end cover clamp are required for proper operation of these affected AD-2 Air Dryers. See Service Data Sheet SD­08-2403 for proper cartridge maintenance procedures.
