    Tef20 diesel engine

    Hi can anyone help me, I have just got my first old tractor project got it home last week and went to put some water in the engine block to find out that the engine block has a few large cracks on it beside the core plugs behind the starter. Does anyone know where I would get a engine block or an engine from. It's a 1955 Tef20 diesel 4 cylinder

    Are you sure it's definitely scrap. plenty of welded blocks around working in machines. If the leaks are all external it could be welded and then any tiny leaks sealed with radweld. Obviously a replacement uncracked block would be desirable but perhaps not that easy to find. Here's a link to download the workshop manual for the grey Fergie for free. There's a section on the TEF20 diesel engine after the petrol one starting on page 16 which states it to be a standard diesel. I do not know 100% for sure that is true because I never worked on a grey Fergie diesel but I overhauled plenty of the later 4cy 35 standard motor company diesels. The injector pump was definitely different but the block might be the same, if you are not doing a concours classic restoration you could probably fit a better later engine but I don't know if that would be morally acceptable to you .I think there were versions of the standard diesel in some very old forklifts and I recall something about the head from an IH being interchangeable. No doubt someone will come along whos's been there and got the T shirt.

    Other more worthwhile engine engines do fit:

    I thought the grey Fergie diesels had a Freeman engine.

    Ferguson only ever used the Standard Motor Company's 20C engine in the TEF20. Predecessor to the 'quality' 23C in the FE35.

    Wot about those with the Perkins P3 - or were they only in Aus?

    And here's what Google disgorged. We are both correct

    https://www.hcvc.com.au/forum/oldjun...reeman-sanders


    And this:

    With Ford and Nuffield offering Perkins engined variants, and David Brown their own engine, it was not long before Ferguson's sales force were calling for a diesel version of the TE-20. Now as Harry Ferguson himself was not a diesel fan, it took some considerable persuasion to get him to agree to a diesel-engined tractor at all.

    The Perkins P3 was looked at, but the cost of installation and the modifications needed would not suit, so a Standard engine was fitted instead. This engine was designed by Freeman-Sanders specifically for Ferguson, and was built for them by the Standard Motor Co., who later developed the same unit for use in their 'Vanguard' car.

    There was one thing which opened the way for a conversion pack from Perkins for the Fergie 20 and that was the fact that the diesel engine supplied by Ferguson could not be fitted to existing tractors. The first tractor converted by Perkins was actually a Ford-Ferguson 9NAN for his own use, but the principles of the conversion were the same for the TE-20. The 9NAN was acquired by Frank Perkins during the War and the engine fitted in this case was a P4, there being no P3's at that time. It was cut up in the mid 1970s under Customs supervision, along with an MF85 imported as a test tractor for the A4-300 engine, as no import duty had been paid on them!

    P3 engined ones were usually fitted as a conversion from a petrol engine tractor
