Over the last few months, I have been combing through the records for Winton, and later Cleveland Diesel, and put together the following master list of every engine produced by them. This is the result of several nights of going through 2000+ pages of entries, and then spending the following several months filling in the gaps with specifications using various manuals, brochures, company newsletters and everything else, and even still, there are many, many holes with the early engines.

The records start with engine #15 – thus I can not fill in those very first engines. Note that Winton assigned model numbers to several of their auxiliary units such as compressors and pumps, and are labeled as such below.

3-2023: Since making this post in 2020, I have been able to fill in a huge amount of holes in this, as well as acquiring an official Cleveland listing. This will be posted in the next few weeks.

The last Winton engine before being purchased by GM was engine number #3559 on 6/12/1930, a model 148 engine for Electro-Motive. Winton was purchased by General Motors on 6/20/1930.

On 12/30/1937, Winton Engine Corp., was renamed to the Cleveland Diesel Engine Division of General Motors. The Final Winton Engine was #5359, A 12-201A for Railroad Service.
Note 1: 4432/3 are the prototype 201 engines, listed as “used 201” in records.

When it comes to horsepower ratings, especially on the later engines (278A, 268A, 567C), there were simply too many horsepower numbers to list, as it varied by application.

Note that by now – we see engines that are made by sister companies including Detroit and EMC/EMD. Early on, the Detroit Diesel engines sold through CDED (typically part of a “package” for a boat) carried both a Detroit Diesel as well as a Cleveland Diesel builders plate. In the case of the Detroit engines, this was dropped by the 1940’s.

However – with the EMC/EMD 567 line, engines sold though CDED for marine and stationary use carried only a Cleveland builders plate well into the late 1950’s. Only the very last few 567 engines sold through CDED carried both an EMD and a CDED builders plate. More information on this can be found on our post documenting Winton/CDED linked below.

Also to note: This list covers only engines built or sold through Winton and Cleveland Diesel. This does NOT cover any additional engines or developments by Detroit Diesel (such as the 51 or 53 series and later) or EMD (184A, 645 etc.)

Thanks to J. Boggess and P. Cook for helping with this. As always, there are numerous holes in the listing, so please send us a message with any additions or corrections.
