SERVICE PROCEDURE
17502
May, 2017
SUBJECT:

SAFETY RECALL
Air Dryer Mounting Bracket on certain 2015 thru
2018 LoneStar®, LT™ Series, ProStar®, and RH™
Series trucks built 05 May 2015 thru 12 January
2017 with Battery Box feature code 08XJZ, 08XHJ,
08XHK, or 08XHL and Cab feature code 16AUX,
16AUM, 16AUN, or 16AUP.

DEFECT DESCRIPTION
The air dryer mounting bracket may fracture, which could cause the air dryer to
separate from the vehicle frame with possible airline separation from the dryer,
resulting in air system leaks or loss of air pressure to the brake system. Airline
separation from the dryer, depending on which line separates, could cause loss
of air in the brake system or increased stopping distances which could increase
the risk of a crash.

MODELS INVOLVED
This Safety Recall involves certain 2015 thru 2018 LoneStar®, LT™ Series,
ProStar®, and RH™ Series trucks built 05 May 2015 thru 12 January 2017 with
Battery Box feature code 08XJZ, 08XHJ, 08HXK, or 08HXL and Cab feature
code 16AUX, 16AUM, 16AUN, or 16AUP.

ELIGIBILITY
This procedure applies ONLY to vehicles marked in the International® Service
Portal℠ with Safety Recall 17502. Also complete any other open campaigns
listed on the Service Portal at this time.

b. If HSA is NOT equipped, proceed to Step 12.
NOTE: Prior to disassembly, mark all air lines on the HSA bracket. This will
help to identify them during reassembly.
8. Disconnect air lines (Figure 1, Item 2) and solenoid connector (Figure 1,
Item 1) from hill start aid valves.
9. Remove two quick release valve fasteners (Figure 1, Item 3).

NOTE: Depending on vehicle application, the number of air lines running
through air dryer bracket will vary.
NOTE: Use a plastic tubing cutter and make sure the air lines are cut
squarely to the tubing. Using another type of tool or not cutting the tubes
squarely can cause air leaks when the tubes are reassembled.
16. Mark and cut each air line hose running through air dryer bracket,
stagger each cut by approximately 2 in (5 cm). Tubes should be cut
squarely. Staggering cut locations (Figure 5, Item 1) helps prevent
union installations from gathering in one location.

UNITED STATES AND POSSESSIONS
The National Traffic and Motor Vehicle Safety Act, as amended, provides that
each vehicle that is subject to a vehicle recall campaign must be adequately
repaired within a reasonable time after the owner has tendered it for repair. A
failure to adequately repair within 60 days after a tender of a vehicle is prima
facie evidence of failure to repair within a reasonable time. If the condition is not
adequately repaired within 60 days, the owner may be entitled to replacement
with an identical or reasonable equivalent vehicle at no charge, or to a refund of
the purchase price less a reasonable allowance for depreciation.
Dealers must correct all vehicles subject to this campaign at no charge to the
owner, regardless of mileage, age of vehicle, or ownership, from this time
forward.
Dealers should proceed immediately to make necessary correction to units in
inventory. All inventory vehicles subject to this recall campaign must be
corrected prior to sale, transfer or delivery. If vehicles have been sold or
transferred and you are in receipt of Customer Notification Letters and
Authorization for Recall Service cards for those vehicles, the transfer location or
customer must be notified immediately from your dealer location.
Dealers must make every effort to promptly schedule an appointment with each
owner to repair his or her vehicle as soon as possible. However, consistent with
the customer notification, dealers are expected to complete the repairs on the
mutually agreed upon service date.
Dealers involved in the recall process will be furnished a listing of owner names
and addresses to enable them to follow up with owners and have the vehicles
corrected. Use of this listing must be limited to this campaign because the list
may contain information obtained from state motor vehicle registration records,
and the use of such motor vehicle registration data for purposes other than this
campaign is a violation of law in several states.
