One cylinder Cat engine found

That's an oil test engine.

Lubricant and other testing. These were made to be torn down, wear measured and then rebuilt with new components for the next run.

Philip - The Caterpillar Single Cylinder Oil Test Engine (SCOTE) was first built by Caterpillar in 1935, to provide a test base for oil quality and oil performance testing. This was done because Cat engineers did not believe that oils could be tested properly, just with bench testing, and other forms of testing such as chemical analysis.

The engine has been produced in sizeable numbers, and supplied to many oil companies and other lubricant specialists .. as well as car, truck and tractor manufacturers, worldwide .. and is still in use by Caterpillar today. These SCOTE engines have been purchased by companies as diverse as Daimler-Benz, GM and Ford.

It is an engine that can be dismantled, inspected and modified quickly and easily .. and which can be substantially altered, via changing various components such as heads, valves, camshafts, fuel systems, etc .. to provide results for different operating conditions and parameters .. and to provide results for different diesel engine designs.

Caterpillar undertake oil testing for any lubricant manufacturer, or any oil additive manufacturer, who wishes to get independent, Caterpillar-certified results on their oils. This process is lengthy and costly, and I suspect not many companies indulge in it, as much as they used to .. particularly since Cat have been producing their own branded oil.
In the ancient past, Cat tested any oil manufacturers product, if offered, and gave it their "blessing", by adding it to a list of "approved lubricant brands". This system has apparently been abandoned since Cat commenced production of their own brand of oils.

Other engine manufacturers such as Petter, have produced oil test engines, using a model from their single cylinder, 4 stroke diesel lineup, to produce oil test results similar to Caterpillar SCOTE results, but faster and cheaper.

This following excerpt, by a lubrication engineer .. one George Leonard Neely (Chevron Corp, Ret.) .. from the SAE book, "The History of Aircraft Lubricants" .. gives an interesting insight into the development of "compounded engine lubricating oils" (i.e. - engine oils with performance-enhancing additives) .. which oils have become such a regular part of our lives .. that we forget, that at one time, engine builders and oil companies just refined oil as it came from the ground, bottled and canned it, and and poured it into engines without any serious modification.

It was only after the first Cat diesels had been in use for a year or two, that ugly oil performance (and therefore, engine performance) problems arose .. that needed the combined efforts of lubrication engineers, and engine-manufacturing engineers, to overcome ..

Very interesting reading😊 ,we take for granted the effort that now lets us run diesels for thousands of hours. I forgot to add that my friend will part with the engine. He hoping someone will get it back to running condition. You can e-mail him at: [email protected]

Wasn't the engine that furnished power assist to the controls of a No. 66 pull grader (No. 77?) also a single cylinder gasoline engine? If so, how can you tell the two types of engines apart?

the grader motor is simialr only because its a single cyclinder.

I have seen a few of those test engines at tractor and equip. shows and one time I think it was in Greenville Ohio that I saw one that was made up from the D17000 V-8 Cat for the oil testing program.The other ones I saw were made up from the in line engines.
