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.
Example:

Official Gazette of the Fede ral Minister of Transport
Directive in respect of vehicl e title docume

Extract from Transpor t Gazette 1973 p. 66
(applies only to the Federal Republic of Germany)
Official Gazette of the Fede ral Minister of Transport
Directive in respect of vehicl e title document (VkBl 1972 p. 354)
Bonn, 28 December 1972
StV 2/36.15.17
Pursuant to the directive relating to the vehicle ti tle document dated 20 June 1972, Part C. No. 9.1, a dash
should be inserted at the relevant poi nt in the place of data which are no longer required in future (e.g. in the
case of the "factory number of engine") in those instances where the olde r type of title documents are used for
the preparation of the vehicle title document.
The question which is now posed is what procedure shoul d be adopted in respect of the vehicle title document
or the vehicle registration document in the event that th e factory number of the engine from the past is still
entered in the older type of title documents and a repl acement engine with a new number is now installed in the
vehicle in question. Following consul tation with the competent authorities in the regions, I now provide the
following instructions:
I. In view of the fact that the fact ory number of the engine is regarded as insignificant in respect of traffic
legislation, no change requires to be made to the vehicle documents. This also does not conflict with 27
Para 1 StVZO pursuant to which the data in the vehi cle title and registration documents constantly have
to reflect actual circumstances. This requirement namely covers only those particulars relating to actual
circumstances which are of significance in terms of traffic legislation. This is no longer the case,
however, in respect of the fa ctory number of the engine.
II. In order to spare the relevant vehicle owner any misunderstandings or indeed possible disadvantages (e.g.
on the occasion of checks when abroad), I recommend proceeding as follows:
In the event that the replacement engine installed has a different number than that entered in the title and
registration document, the figures in the column "e ngine factory number" shall be deleted and the following
endorsement made at a suitable point both in th e title as well as in the registration document:
"Entry of engine factory number no longer necessary".
If the endorsement is made close to th e deletion, it is sufficient to state:
"Entry no longer required".
The Federal Minister of Transport Ip. p.
