I was helping a friend of mine tear down the engine on a Ferguson today, either a 20 or a 30. There is no serial number tag on the dash so we don't know exactly what it is or when it was made. The engine does have some casting numbers high on the right side of the engine block. They are 7-12-4. Does that refer to anything as to date of engine block manufacture? Also, is there any way to tell if it is the 20 or 30 series? Any other way for an ID of the year of the tractor since the serial number plate is missing?

That's it, just proves that a picture is worth a thousand words. My friends is no doubt the same tractor, somewhat rougher shape mind you. Thanks to yourself and everyone else. Now if we just had that serial number ....

If the oil filter is inside the oil pan its a TO20, if it has the oil filter on the left hand side outside the engine its a TO30. If you look on the rear axle castings, very often there is a casting date that will give you a clue as to when it was made, just allow a couple of months for the casting to be held in stock before assy.Is It a Continental engine though, if it is its a TO as above..the oil filler on a TO is front left of cylinder block On a TE20 it at the rear left of the block so that will have a Standard engine (just to confuse everything)..Because you are in Alberta it could be an TEA made in UK, lots of TEA's in Canada, they look like a TO just different engines.Let me know what you find plz.

Mike I would also like to reply...add to the confussion.

Look at engine casting center lower left side. If it is a Z120, Z129, or Z134 as Ray describes you have a TE-20 or TO-20, TO-30, or TO-35.

Note I included the TE and TO-20 with the Z120 engine. If you do not have a Z### engine then look for the indications John(UK) describes and most likely you have a standard engine which makes you tractor a TEA-20.

The TE-20 has a contential Z120 engine
The TEA-20 has a Standard engine (this is what john describes as a TE-20)

The Difference between the TE-20 and the TO-20, which both have the same Z120 contential engine is the electronics. The TE-20 has Lucus parts while the TO-20 has AC Delco.

I know it can be confusing but take this list and look over the engine and note the points brought up here and let us know.

I was actually meaning a TE20 or a TO20 the TEA20 was an afterthought If you look at the engine like I said, you should be able to determine what it is from the description. The location of the oil filler is the clue and the type of oil filter is secondary clue.Believe me I would not call a TEA a TE20 there is a big difference. Peace to you all!

John, you said..."Is It a Continental engine though, if it is its a TO as above..the oil filler on a TO is front left of cylinder block ..... .On a TE20 it at the rear left of the block..... so that will have a Standard engine (just to confuse everything).."

My understanding is that if it has a continental engine (specifficly a Z120) then it is either a TO-20 or a TE-20 and the oil filler on both these tractors is front left. The difference is whether it has AC DELCO (TO) or Lucus (TE) electronics.

If it has a standard engine then it is a TEA-20 in which case the oil filler may be at the rear of the engine... I do not know as I have never examined a standard engine.

My TE20 (SN: TE 294XX) has a continenatl Z120 engine and the filler is in the front left and all my manuals (Owners, Shop and I&T) never discuss a left rear filler.

I was under the impression that you maybe left out the "A" in the above sentances. If my understanding of the various models is not correct I would like to be better informed.

Respecfully Jeff

Well unlike you in the USA we have all these different configurations of the tractors and we do normally call all the different models by their code i.e TEA/TED/TEF/TET/ etc.etc(17 variations on the tractor) but we call the WHOLE range no matter what the configeration, TE20. As we we weren't actually trying to find out which specific tractor it was (that would be the next stage if it was a TE20)just whether it was a TE or a TO. The reference to the Standard engine was just an afterthought on my part as I was finishing the reply, I just put that in just in case it was a Standard engine, I thought if I didn't say that and if it was a Standard Engine when he checked it would only raise another query, I hoped by saying that he would know straight away and it would solve his problem once and for all. You are correct in thinking that the differences between the original TE and the TO are the electrics, but there are also differences in the gearbox, Brakes,Steering box & Clutch.Hope that goes some way to explaining it all.

Well, John, with that said, we are saying the same thing. The problem arizes in the all to often mis-conception over here in the States that the TE20 has a standard engine. The TE-20 has the Contnetinal engine same as the TO-20, (differences as you have described). Even my local tractor repair shop guy I work with does not have this straight. The standard engine parts are harder to come by here than Z120 parts.

Bottom line: If you have a TE, then at least here in Ohio, you need to know if it is a TE-20 or a TE(A,F, etc.)-20 to get the right parts.

Correct (I think) Sparex have a lot of Standard engine parts available and if ever you are really stuck for something, dont forget the guys with the Triumph sports cars,the engine is very similar and a lot of parts will interchange.

Hi Mike! To add to John's post, the TO series engines may be identified by the numbers just above the distributor. Z120-120ci engine used in TO20; Z129-129ci engine used in TO30; Z134-134ci engine used in TO35.
