With all do respect to the others who have posted...

Here is how you id a T__-20. There are basicly three styles I am going to deal with here. The TE-20, the TO-20 and The TEA-20.

To Start, as Mr. Chapp has indicated look at the engine. If it has an internal oil filter and has the numbers Z120 cast into the lower left side of the engine it is either a TE-20 or a TO-20. The Z120 is Contential motors engine. If it has a standard motors engine it will have an external oil filter left rear of the engine. This is a TEA-20.

To differenciate between a TE-20 and a TO-20 the easiset view able difference is the transmission shift plate. If the plate the shift lever goes through is a seperate roughly square piece then it is a TO-20. If the plate is integral to the steering column then it is a TE-20.

Other differences exist but this is a simple quick check.

Also, there is an alphebet soup of lettered TE___-20"s TEB-20, TEC-20, TED-20 tec. however, these are rarer specility tractors mainly having to due with fuel type, and use (i.e. vinyard) the most abundant of the other letter types is the TEF-20 (diesel engine).

Hope this helps.
Jeff

Hi Tony... Let's start with does it have an external oil filter? Second, is the engine id plate there? It should be on the left rear of the block in most cases... what is the number? Now we'll have a starting point.

No oil filter on the outside could be a TO20 or a TE20, same engine you see. Check the metal the gearbox is made of, if its cast iron its a TO20 if its aluminium its a TE20

Since the housing over the gearbox is iron (magnetic) I'll assume a to20, but I have the starter switch which uses the gear shifter, and the part to replace it is only found in the te20 parts category (here).
Any Ideas on this. The exhaust manifold is cracked, so I should replace it. I know I need to be sure what tractor I have before I order any thing.

From what you say about the gearbox it is a TO20. The starter switch, I was always under the impression that it was the same as a TE but from the parts list I see it is a different pattern, but it mounts the same way. You could check the switch itself before you order one as the contacts burn and the switch can be adjusted, so open the switch and clean the contacts first, unless you know the switch is U/S. then replace the switch and reset it by sliding it forward or back on the elongated mounting holes, you should use a lamp or meter tester to make sure that it is making contact when you operate the gear lever, make sure the pressure on the switch is firm (not too firm though) not just barely making a contact or they will burn again. When you remove the switch tie some string or cord around the operating rod inside so if you drop it you can get it back in place without too much hassle. It is advisable to replace the manifold if if it is cracked as it could draw air and weaken the mixture, depending where the crack is.If it is the exhaust part that is cracked then it could blow fumes out and they are not good for your health. The Sparex part number of the switch (TE style)is S42538 MF #829960M91. The manifold is Sparex part # S60036 or MF part # 1040903M91 or 1750343M91. If you need the manifold to cyl.head gasket that is Sparex S60036 or MF# 1750343M91 These parts may be ordered from this site or from your local tractor dealer. While you are repairing the starter switch you could move the ground lead on to one of the starter mounting bolts if it isn't there already, as it will make a much better contact there and help the starter to spin the engine over faster. You may find that switch, if it is a Delco type, will have a part number on it and you may be able to buy one from your local auto electrical dealer. If you do find this number I would be grateful if you would let me know what it is so I can add it to my list.

No external oil filter would be a to20. tes had a filter outside the pan. Maybe some of our other friends can shed more light...Good luck, have fun!!

My Ferguson is missing the I.D. tag under the steering wheel. There is a serial # on engine left side.S105845E. From the information here I"m asuming it is TEA 20 built in 1949. It has an oil filter on the left side. The shifter lever plate is part of the steering box, the transmission housing is aluminum. The A does that mean it has a Standard engine? I need a ring gear and a 9 tooth gear for the 6 volt bullet nose 2 bolt starter. I"m on Vancouver Island B.C. Can. Can anyone close by help or recommend a parts supplier? Thanks.
