Weil ich finde, daß dies nicht verloren gehen sollte.....
Alles anzeigenSpeaking of the part number logic in the post xxxxE number era you have:
1) a two-digit year of design code (sometimes preceded with a letter: P-panels, A-accessories, H - an RS part, etc.); then
2) a two-char engineering group prefix which is a tricky part
One should start decoding it from a SECOND letter as follows:
- F/M - engine group
- B/G/R - regular parts group (the code here also denotes the country of a project; B - Britain/G - Germany/R - Argentina)
- T - transmission group
and then you can move to the earlier char:
a) for the engine group (F/M) - it denotes the engine type:
1 - Crossflow
2 - Essex
H - Pinto
T - Cologne
examples: 711F..., 70HM..., 72TF...., etc.
for the regular parts group the first letter denotes model:
A - Escort
B - Cortina
E - Capri
F - Fiesta
G - Granada (or Ford P7 for pre-1972 codes)
P - Ford P6
V - Transit
Z - Zephyr/Zodiac Mk4
examples 69AB/69AG - Escort Mk1, 71BB/71BG - Cortina Mk3/Taunus Mk1, 74EB/74EG - Capri Mk2, and so on...
c) in the transmission group - it has, of course, meaning of the transmission type:
9 - Type 9 gearbox
E - Type E gearbox
etc.
examples 839T - T9 from a '83, etc.
3) After the 4/5-character long prefix comes the base number which gives you a glance what an actual parts is. It's another 4 or 5 digit number starting from 1000 which can have a letter before or "inside" (between the hundres and thousands part).
Base numbers 2000-3000 are reserved for the brakes parts, 4000-4300 for the rear axle, and so on...
The is a comprehensive list of the meanings at the bottom of this page: http://www.fomoco.org/Part%20numbers.htm
For example - 71BB-3392-... is an upper arm assembly on the front suspension of a prefacelift Mk3 Cortina, 71BG-4010-... is a rear axle housing assembly on it, and so on. Sadly, the exact base number of a certain part can be determined only using factory parts lists but the good news is that they have the same meanings along all the models so 69AG-4010-... would be rear axle assembly on an Mk1 Escort and 78EB-4010- an axle assembly on Mk3 Capri etc.
If there's a letter before the base number it means it's a body/interior/trim part. The letter SHOULD denote body type (using the codes from id plate: T - 2dr, F - 4dr, C - coupe, N - estate, etc.) but it is sometimes misused in the catalogs so not 100% sure if this is it. The trim parts also have a separate numbering sequence found just below the earlier list on the page mentioned above.
For examples:
P71BG C20125 AA is a complete door assembly on a Taunus Mk1 Coupe, while P71BG T20125 AA is the same for a 2dr Taunus Mk1 / Cortina Mk3.
4) The last part is the suffix which denotes specific application, engineering revision, etc. - there's no common coding for this, but some patterns can be seen.
For example the suffix can consist of two letters:
... - AA, ... - BC, ... - AD, etc.
Most of the time, the first letter would mean some major engineering differences within a single part (like LHD/RHD versions, or specific engine application of a single part, etc.). For example let's take a direction indicator stalk for the LHD Taunus/Cortina - 71BG 13335 AA and its RHD version - 71BG 13335 BA.
The second letter would then mean a minor revision of the part's design (like for example from 7/1970 to 8/1971 they used part ...-AA, then until 9/1972 they used part ...- AB, and finally for the rest of production run an ....-AC was used, etc.)
The suffixes of course can have three characters (most common in the letter-digit-letter form, like ...-A1E) or even four (most of the parts that include color version - trim/plastics, etc. - use suffixes like ...-AAHU, where the first two letters PROBABLY have the same function as the two-letter suffixes discussed above, and the last two denote color).
Hope this clears the Ford part numbers logic a bit...
