USE OF ENGINE NO. WHEN INSTALLING RECONDITIONED ENGINES AND FACTORY-NEW REPLACEMENT
ENGINES OR CRANKCAS ES - AH01.10-P-0001-01A
All engines
The engine number has a different le gal significance in individual countries. In the Federal Republic of
Germany, for example, it has been cl assified by the legislative authorities since mid-1972 as "insignificant in
terms of traffic legi slation". It is therefore no longer included in the vehicl e title document and vehicle
registration document.
Practically all other countries continue to require the indication of the engine number on motor vehicles which
are registered in such countries. In dealing with internat ional traffic, the authorities proceed on the basis of the
provisions of the country in which the vehicle is registered.
In order to avoid any problems on the occasion of vehicl e checks or when crossing international frontiers as a
result of the lack of or in correct engine number, the fo llowing directives have to be observed when carrying out
repairs.
1. Directives for vehicles wh ich are registered in the Fe deral Republic of Germany
a. In the case of vehicles for which no engine number is indicated in the vehicle registration
document (first registration after a pprox. mid-1972), it is not necessa ry to stamp or revise an
engine number if a replacement engine or crankcase of the same type is fitted.
b. If an engine number is indicated in th e vehicle registration document , it is possible, if an
engine of the same type is fitted, to transfer the number of the removed component to the new
engine, or the appropriate authority (vehicle in spection authority, vehicle registration authority)
should be requested to delete the engine numbe r in the vehicle title document or registration
document. The German Federal Mini ster of Transport has issued appropriate ministerial orders in
Transport Gazette 1973, p. 66.
2. Vehicles which are registered outside of the Federal Republic of Germany
If a reconditioned engine or factory-new replacement engine or crankcase is fitted and this is of the
identical type, it is then necessary to adopt the engine number of the engine removed and to transfer it to
the new engine or crankcase.
For this reason, pay attention to th e particular directives stated in Para 3 for the installation of
reconditioned en
gines, crankcases and shortblocks.

3. Special directives
3.1 Installation of factory-new repl acement engine of identical type
a. If a factory-new engine is installed and an engine num ber is required (e.g. vehicle registered
outside of the Federal Republic of Germany), the number of the factory-new engine must be
ground off and the number of the originally instal led engine of identical type stamped in its
place.
b. If the factory-new engine is fitted with an e ngine type plate (older car engines) and it is
necessary to indicate an engine number in the ve hicle documents, in this case take the engine
type plate off the engine remove d and affix it at the same point on the engine of identical
type to be installed.
3.2 Installation of recondition ed engine of identical type
a. The reconditioned engine plate must not be re moved either from the reconditioned engine to
be installed, nor from the engine removed, if the latter was a reconditioned engine.
b. If the engine removed is fitt ed with an engine type plate (older car engines) and it is
necessary to indicate an engine number in the vehicle documents, the engine type plate then
has to be taken off the engine removed and a ffixed at the same point to the reconditioned
engine to be installed. This plate should be affixed in addition to the reconditioned engine
plate.
In the event that a vehicle owner has problems on the occasion of vehicle checks or when crossing
international frontiers be cause of the lack of an engine num ber, the workshop in question may in
certain circumstances be held liable.
After replacing an engine , the engine number has to be altere d in the vehicle maintenance booklet
and on the vehicle data cards as well as in the re pair customer file. These documents should clearly
show which engine is installed in the vehicl e in order to ensure smooth parts service.
In addition, the copy of the vehicle data card which is held at the Parts Department of the relevant
Branch or Importer shoul d also be altered.
3.3 Model designation id entification of crankcases and shortblocks
Crankcases and shortblocks available in the parts sector are not provided with an engine model designation
identification and also not with an engine number.
To make it possible to identify the engine on the occas ion of vehicle inspections (e.g. by an inspection authority
when a vehicle is taken out of service or at the Customs on the occasion of importation of vehicle), the
workshop carrying out the repairs has to stamp the engine model designation in the crankcase or the shortblock
in the space provided fo r the engine number.

2. Changes to the standard condition may decisively influence the new vehicle warranty, since our warranty
obligation does not cover damage resulting from a change to the original Daimler Benz delivery
condition.
3. Proper supply of parts is no longer ensured when major components are replaced.
4. The exchange procedure is based on the "Identical unit exchange" principle. For example, an identical
model reconditioned unit will be supplied in return for a damaged engine. Only then is it possible to be
credited for the returned damaged engine.
Customer inquiries and requests of this type should be answered along these lines in order to ensure that the
quality standard of our vehicles is not impaired.

General
The weather station's barometer must be calibrated to the air pressure specified by the local meteorological
office.
The measured performance value must be corrected with correction factors.
There are two 2 correction factors:
Altitude correction factor
Performance correction factor
Performance correction formula N
eo = Ne x KH
Neo = Performance in reference to normal operating conditions in kW.
Ne = Performance measured on the output dynamometer in kW.
K
H = Correction for intake air temperature, barometer level and altitude of the relevant test location.
Calculation example
1. Read air pressure, altitude and intake air temperature of the test location off at the weather station. NOTE: In addition, vehicles registered in the Federal Republic of Germany are subject
to the law which revokes the operating permit as a result of conversions which
change the model. We cannot issue a Certificate of non-objection for individual
approval by the technical motor vehicle testing authority in each case.
