Federal EPA Regulation: Gliders with Rebuilt, Reused or Remanufactured engines.
This may assist dealers with information related to using older EPA engines in a Glider Kit.
There are two primary Federal ruling government bodies involved. First is the
Environmental Protection Agency (EPA); second is the IRS as related to possible F.E.T.
(Federal Excise Tax) exemptions. This letter will concentrate on Federal EPA. For more
details of F.E.T. and possible exemption see www.irs.gov Ruling 91-27.
Gliders are governed by NHTSA as identified via the control VIN. Further details can be found at:
www.nhtsa.dot.gov/cars/rules/interps and related sites.
Gliders are identified by the 4th character in VIN; always an “X” on Daimler branded models.
The glider body and frame contains the newly assigned Glider VIN. Glider VIN is stamped with
the model year they are created not that of the donor VIN being replaced.
Completion of the glider and compliance with all Federal, State and local regulations is the
responsibility of the final assembler (final OE) usually the customer. Consult your legal advice and
or IRS and tax consultants for clarifications. Gliders as built by the manufacture may contain up to
but not more than one major component from the manufacturing plant of Engine or Rear Axle as
required to not constitute a newly manufactured vehicle and all compliances implied. The Engine
must be a Remanufactured vs. New.
A glider order and subsequent completion (final assembly) does require a “Donor Vehicle” VIN. In
general a like Class 8 Diesel, any brand that the Customer or Dealer possesses, has clear title to
and is or will no longer be in service. The donor Serial or VIN in many states is actually required
on the new Glider title and registrations forms. A Donor VIN may allow you to re-build or re-use
older EPA technology when replacing a worn vehicle, minor wreck or replacement vehicle, with
same or newer EPA (cleaner) engine than the original donor. i.e. A replacement of a 2004 EPA
vehicle can not use a 1998 EPA engine. State regulations may be in addition to Federal
regulations; currently we are only aware of California CARB restrictions to the federal ruling as
related to EPA. State regulation compliance is the responsibility of the final assembler.
THE EPA RULING
You may search the internet at www.epa.gov “Laws and Regulations”.
Including: EPA Section 40 CFR Part 89.130 and 86.004-40 Re: EPA420-F-02-235.
Primarily as applied to Gliders with rebuilt, reused and/or remanufactured engines is as follows
below (attachment) for reference. Please check Federal, State and local regulations often for
exemptions and changes. Daimler Trucks North America LLC does not and can not guarantee
compliance as by definition we are not the final assembler. Not every situation is covered here
and suggest you consult DTNA and other sources for exceptions. When we install a
remanufactured engine in a glider kit per dealer request, it’s with the full understanding the dealer
Daimler Trucks North America LLC
or customer has a donor vehicle VIN that qualifies him for that EPA year and has considered all
federal, state and local regulations.
Usage of remanufactured engines, reused and rebuilt engines in replacement vehicles and
Gliders is Controlled by EPA Section 40 CFR Part 89.130 and 86.004-40 , Re: EPA420-F-02-235.
