TEF top speed and fuel consumption

[Rob Reznik]

Hi - I have a couple of TVO's but am considering buying a diesel TEF for a project I have in mind. Important info I need is fuel consumption ( would be good in mpg's but I understand it maybe in hours) - also top speed - I know this will be low but are there aftermarket gears that can be bought to increase it?

Many thanks in advance.

I've driven a few TEF20s. They have the same transmission gearing as the TEA20 and I suspect are governed around the same maximum engine RPM?

If I am correct, a TEF20 should have the same top speed as a TEA20 or TED20. Don't know the fuel consumption but being diesel it should be a bit less than a TEA/TED20.

As for increasing the top speed of a TEF20 I would urge caution. My TEA20 at full throttle is not the most stable machine, especially over rough surfaces and I suspect increasing the top speed could make the tractor rather lethal.

Do a couple searches, like wikipedia, and see which English sedans had this engine- if you aren't interested in the tractor itself, search under 'Standard motors 23C diesel'. There might be a 5 speed with OD out there for you on Ebay

Tony. We must have posted at the same time? I don't believe the Standard diesel was ever fitted to automobile. A similar Standard engine was fitted to the Vanguard sedan from the late 1940's to mid 1950s; the Triumph TR2, TR3, TR4 sports car; and Morgan sports car but I believe the bell housing (and a number of other external engine features) were quite different. Certainly the transmission and bell housing was totally different.

As the Standard engine is governed I suspect the governor could be altered to increase maximum RPM and thus increase top speed - but there is no way I'd mount a Fergy that goes any faster than my TEA20, especially with normal Fergy brakes........

Wikipedia seems to be down tonight. I 'think' that is where I read that this engine powered some sort of car. We will have to wait for John to give a final verdict...

Thanks - I've already checked Wikipedia and nothing there - I'm a big traveler ( British and currently live in Laos ) and was thinking of driving one around the world or at least doing a big trans continental trip. I've seen many strange vehicles on the road but never a tractor so thought I would build a smallish trailer for it and give it a go. I know my own TVO's are not that good on fuel and would estimate top speed at around 15mph but could do with it being a bit higher so that I could cruise more comfortably at a lower speed - thanks in anticipation.

The diesel was fitted to the standard vanguard car,but for reliability I would opt for a 35 or 135 multipower the extra gears will also give you a very good road speed, about 21 mph ! plus parts are difficult to source for the standard diesel in most countries but the 35/135 parts are covered by most after market suppliers and thus are available in nearly every country of the world and you will be amazed by the fuel economy. Contact me by e-mail I would like you to record your journey in our Ferguson magazine. (FOFH)

thanks - I was thinking of rebuilding the original engine in the UK before starting and I like the thought of using the old grey fergie - having spent a lot of time in third world Countries its amazing what can be fixed on the side of the road and what improvisation really means!! - possibly wont start the trip for another 6 or 18 months as I would need to leave the UK during the spring/early summer to avoid too much cold weather/Snow in some Countries on route - email address is [email protected]

thanks again

The road speeds will be exactly the same as the TED as the engines both run at the same governed speed. You can fit larger diameter tyres and inflate them a little more than normal, that will make the rolling radius as large as possible and this will increase the road speed. If you can work it out, the gear ratio is 2.98:1 in 4th gear. The brakes will need checking that they are adjusted and set-up correctly,(they are self-energising which helps) if they are they should lock the wheels easily, so you can't increase the braking efficiency any more than that. These same brakes were fitted right up to the mid 70's on the 135 and some even later models, you could fit new brake drums which would improve things even more. If you need the information about setting up the brakes, just ask me and I will send it. There are two different types of brakes fitted so you would need to tell me which type or give me the serial number of the tractor for me to work it out. You could also fit new complete Brake Back Plate Assy's to each side they sell at about £90 per side. Anyone who says the brakes aren't powerful enough, don't have them set correctly as they will lock the wheels and you would also use the engine to brake as well. The tractor would use the 3 ton trailer quite happily, fully loaded (even over-loaded).
Fuel Consumption is difficult as they never quoted a figure at that time and it will vary greatly between running light on a smooth road surface to running in 2nd gear heavy ploughing. I would think that you could assume to halve the consumption against a TED or near enough anyway. If you have the injectors and the Pump serviced and calibrated that too would de-crease fuel consumption without losing any [email protected]

It was the same engine (Standard 20c) but with a different block so it would mate to an automobile transmission..The engine was used in the Sedan, the Van and the pick-up. BareCo have a van fitted from new with this same engine, but it wasn't really suitable for auto use, it only had a pneumatic Governor which made it sluggish, but it was quite economical.John

An Australian made Chamberlain tractor "[i:2ffa375e5e]Tail End Charlie[/i:2ffa375e5e]" was driven around Australia, 3 times:

I recall this tractor passing through our town. 10,419 miles in 19 days would have been really motoring!

From the before and after photos above, it may give you some idea of the required "enhancements" for long distance cruising - note the mud guards, front shock absorbers, mirrors, head lights and tyres! :lol:

Chamberlain tractors were Australian designed and made, sold between 1949 and 1970 until taken over by John Deere. Many Chamberlain tractors remain in service today, being very highly regarded by their owners.

BareCo's Standard Vanguard Service Van mentioned by John. I didn't realise this had a diesel engine.
