Are you sure you don't have a TEA 20?

Hello Paul, I know...I"d never heard of a TEA30 either. I did some searches on the net and found one for sale in Canada. There"s a parts dealer nearby who
has been able to come with all the needed parts....he said the only external difference between the TEA20 and the TEA30 is the angle of the oil filter (on my tractor it is diagonal). I"ve looked through my books for information on a TEA30...and haven"t found anything. I did find a reference to a TEA25 in "Vintage Ford Tractors" by Pripps/Morland. In 1951 the HP was raised from 23 hp to 28 hp...they said those are sometimes referred to as TEA25s. It would make sense that there would be a TEA30...After all there was a TO30 after the TO20. If anybody could shed some light on the topic...I"d appreciate it. Maybe someone from Canada or the UK has seen more TEAs, etc. Thanks.

There is no such thing as a TEA30.
He is right; there was a horsepower increase as at serial number 172598 the bore was increased from 80 mm to 85 mm.
The nicknames used to differentiate these are (TEA) 20-80 and 20-85.
Early on in production, the angle of the oil filter did change from vertical to inclined. This was within the run of the 20-80 though, so the sloped filter doesn't help tell you what model it is.
So, the 20-85 is roughly the equivalent of the TO30. After these, in Canada, we got both TO35 and FE35 models.
You can see some of the changes that occurred through the production run at the link below, which should help narrow down when it was manufactured.
Hope this helps,

Hi Jim, Thanks for the information and the link, I appreciate it. What octane fuel do you run in your Fergusons? I'm getting a little engine knock...I like to start with the simple (and cheap) possiblities first. Oddly enough there are a few TEA30s registered in the Tractor registery on this website...I wish I knew why people started referring to some Fergusons as TEA30s. The Serial number plate is in good shape...too bad it doesn't have a model designation on it :<)
It'll be interesting to place when the tractor was manufactured. I'll print those webpages off as reference material to keep with my manuals. Thanks again,

Two more things I meant to mention -
Don't know about the TEA30 question; maybe some people call them that but I have always thought they were just a bit mixed up.
Second, timing is easy to set. There is a hole just below the starter motor. A piece of 9 gauge fencing wire fits in there just perfectly. Stick it in and it will slide into a matching hole in the flywheel just when the points open for #1 cylinder, if everything is right. (Timing is 0 degrees.) You can loosen the bolts at the bottom of the distributor to rotate it to set it. Often the distributor is completely stuck in position due to years of sitting necessitating removal of the assembly, heat, penetrating oil, and such. (Take note that there are two sets of bolts there that can be loosened.)
Hope this helps - I went back and read your orhginal post where you mentioned you'd like to start with the easy stuff!

Hi Jim, Lot's of good information...I appreciate it. I'll look at the timing first. This thing hasn't
run in a couple of years...amazing how these things can be abused and still fire up. The more it runs the better it sounds. The odd thing is the
knock comes and's not consistent. I haven't put the tractor under a load yet...just gone around the yard with it. It's going to be a few weeks before I get to fool around with it much. I'm busying with a house addition. Lots of drywall to tape and mud, paint, etc. Thanks again,

Hi Steve,
You will normally hear a little valve noise on these since they don't have hydraulic lifters, but not too much I guess. I have found that the rocker arm tips do wear, making valve adjustment difficult if not impossible.
If it's a deeper knock though you may be into main or big end bearings, and it's probably wise to deal with them before they score thae crank, if they haven't already. You can change the big end bearings just by dropping the oil pan but for the mains you have to split the tractor. (You can take the cap off the centre one to take a look without splitting it.)
I guess what I'm saying is I doubt the knock is fuel. I am running regular gas from the local corner station, don't know the octane rating. I'm sure it's the same as what you would have there though.
Try using a length of tubing with one end in your ear to pinpoint the location of the knock. If it's up higher perhaps it's piston slap.
Whatever, I think you're in for a bit of work. (Of course this all assumes the timing is set and the problem persists.)

If it isnt the timing as Jim suggests (very often it is) Does this only occur under load or at idle? it may be little ends rattling, they do on this engine if they get a bit of wear in them, but nothing to bother about it's just annoying thats all. You can check if it is that by removing each plug lead in turn when its idling.If it is when it is under load its as Jim says, check the timing they dont like being too advanced.If you still have problems and you think it is timing mail me at fergusontractors at hotmail dot com and I will send you the pages from the TEA Service Manual.. there are 3 variations of distributor on a TEA depending on the engine number and they all time to different degrees. But give me the engine number and the distributor number if you do.

Hi John, I appreciate the help. It might be a little bit before I get to it. I'm busy with a house addition. I've always liked Fergusons. This one is replacing my MF135 (sold it to a friend). My project tractor is a wreck of a AC WD45. Maybe after that one is done...I'll look for another Ferguson. Thanks again, Steve
