Engine Serial Numbers (VIN Number)

web page under construction

Overview

This page details engine serial number location, dates, and identification for Ford-Köln Model A, B, and G28T type engines built at Köln, Germany from the 1930's through 1950's.

These engines carried serial number prefixes A, AA, B, BB, and G28T, among others. Ford-Köln used serial numbers assigned from groups of numbers granted by the Rouge from within the larger sequence of Rouge numbers.

The engine number was assigned to completed engines after they had passed the electric motor-driven engine run-in (run-off) tests and were released for vehicle final assembly. The engine number then became the serial number for the completed vehicle after final (vehicle) assembly.


Model A, B, & G28T Engine Serial Number Location

Model A, B, & G28T engine serial numbers were hand-stamped on the left hand side of the engine block, above the water inlet as shown above. There were variations in the spacing, position, orientation, and sharpness of individual numerals due to the manual alignment and stamping operation.


German (Köln-built) Model A, B, & G28T Engines (Rouge number series)

The table below indicates series or groups, of numbers which are known to have been transferred by the Rouge to Ford's engine production facilities at Köln.

Those numbers were reserved by the Rouge for Köln's local production use and assignment on both engines and vehicles they produced throughout the 1930's to 1950's, continuing well after US Model B regular vehicle production had ended.


The Model B and BB engine serial number is separate from the prefix letter(s). The serial number is unique and is not directly correlated to the prefix letter(s). The prefix is preceded by a ☆, and the serial number is followed by a closing ☆ character.

The G28T engine serial number is separate from the prefix. The serial number is unique and is not directly correlated to the prefix letter(s). The prefix is ☆28☆, for example, and the serial number is followed by a closing ☆ character.

Model B & G28T Engine Serial Numbers


German 1936-41 Model B Engine Serial Number Location

German Model B series engines from 1936-41 used a slightly improved version (ignition and carburation) of the original 1932 Model B engine, prior to the implementation of the yet further-improved 1942 G28T 'B' engine having insert bearings and pressure oiling, and downdraft carburation.

The left hand side of the Model B engine block casting often had the Ford script, as well as the "EB" logo mark of Eisenwerk Brühl, the German foundry that produced the block casting for Ford-Köln. The pic below was suppled by Wilhelm Andersen of Norway.

I am seeking further information and photos about these German 1936-41 series engines, their improvements, and their prefix(s), serial numbers, and format.


German G28T Engine Serial Number Location

1942 and newer German G28T (improved Model B) engines were used in Ford Ruhr, B3000, and FK Series trucks (and Claas Mähdrescher combines) through the mid 1950's. The G28T had insert bearings and pressure oiling.

The G28T carried the engine serial number stamped on the pad above the water inlet on the left hand side of the block, the same location as all the earlier Model B's.

In addition, the left hand side of the engine block casting had the Ford part number G28T-6015 and a date code cast-in, as well as the "EB" logo mark of Eisenwerk Brühl, the German foundry that produced the block casting for Ford-Köln. Many blocks also had the stylized F-K logo cast-in as well.

I am seeking further information and photos about these German G28T series engines, their prefix(s), serial numbers, and format.
