For reimbursement of past repairs, unless noted above as not eligible, file a claim in accordance with the
warranty procedure manual.
Attach an invoice and receipt to the claim to document the repair and payment made.
In addition, attach receipt of reimbursement made to customer for the initial invoice/costs of repair.
Retroactive claims without these items will be denied.

Warranty
The emissions warranty will cover the repair costs for any failure of an emissions-related part described in this
bulletin that results under normal use and service, caused by a warrantable failure, which must be the result of a
defect in material and/or factory workmanship. Reimbursement will include:
• Parts
• Labor
• Consumables (when not reusable)

N OT E
Cummins-powered chassis do
not have Extended Emissions
Coverage under this bulletin.

PROACTIVE REPAIRS ARE NOT COVERED BY THIS PROGRAM
Towing will only be covered if 'engine' emission component failure occurs within the base engine period of 24
months/250,000 miles/6,250 hours, whichever comes first. Outside of base engine coverage, towing and travel are
excluded.
PACCAR will pay for reasonable labor costs for engine removal and reinstallation when necessary to repair a
warrantable failure.
The emissions warranty is retroactive and applies to qualifying warrantable failures that customers have already

had repaired at their expense.
