Hi Curtis;
This is an unusual tractor, any chance of posting a photo of it.
I agree with Rod, 4610 were always 3 cyl, and 4810 were 4 cyl, a derated 5000/5610 engine, I believe pistons were "square" ie same size stroke as bore as per the original 1966 Ford 5000 engine.
Maybe its been fitted with wrong decals - has it been repainted & re-decalled in the past by a dealer.
There were a very few 4810's sold here in England, cancelled export orders which were sold to a couple of main Ford dealers to "get rid of them" !!! Whatever it is, if its tidy & running well, you will have a very nice tractor. Keep us posted with your "news".
Regards David

Hi Curtis;
Sorry cant tell you everything you want to know but maybe this will help you a little:-
Unit 8j09b I believe is build date
8=1988 j=September 09=9th b=day shift.
I am confused because you say its a 4610 which were always 3 cylinder diesel engines. Ford also made a few 4810 models in Basildon for export which were fitted with 4 cylinder diesel engines which were de-rated 5000 engines. These 4810's were successful and ford then launched the 30 series (new style) and the 4 cyl became the 5030, and the 3 cyl became a range of 3430, 3630, 3930 with varying HP according to engine cubic capacity & fuel pump settings.
Hope this helps you a bit.
Cheers David

Would it be possible that this tractor has a 5610 engine in it? Thanks, Curtis

Yes, that is entirely possible.

The next question is this: do the numbers on the hood match the numbers aft of the starter. There's a flat spot there that should have the serial number, model number and the unit code. Match them to the hood tag. Betcha got the 5610's hood along with the engine. That's why the engine number matches the hood. The front clip is still from the 4610, so you don't know the difference at first glance...

Rod, the numbers on the engine match the hood .
Now, was this common practice to put a 5610 engine on 4610 tractors? or were these special orders? Thanks, Curtis

Curtis,

If Ford did this deed, then it wouldn't be branded a 4610. It might be a 4810, but I've never seen one. I'm a bit more familiar with the 5030 which uses the 5610 engine mated to the 30 series back end. I suppose it is possible that Ford did do some custom jobs... but I doubt it... and if they did, it would have some designation.

From your post I took that you compared the engine date code on the upper right front mounting lug of the engine. The date code is stamped there, and on the hood tag as the "ENGINE" number. As from my previous post, you can also compare the serial, model, and unit numbers in the same manner, which are found on the transmission housing aft of the starter. If you go to the same general location on the left of the transmission you should also find the transmission number found on that tag. There are also similar numbers for the rear axle and the hydraulic lift, although I can't say that I've ever tracked one down to tell you where to look.

I think it most likely that your tractor has had an engine "fitted" by somebody like "me" who would be amused by that type if project. There were some speciality companies in the UK that I've read about doing that type of work too, so it could look quite professionally done.

The only 4 cylinder, line assembled 4610's that I'm aware of were those shipped to south africa which were fitted with locally assembled Perkins ADE 236 engines. Otherwise, a 4610 should be fitted with a Ford 3 cylinder 201 from Basildon. I'm curious how that engine code checks out. Let us know.

These numbers are on the right front mounting lug. emad 60S02 6j6a The engine serial number on the flat by the starter matches the serial number on the hood. Thanks, Curtis

Curtis,

OK. The engine date code is 6j6a, This would date the engine to either 1986 or 1996, September 6th of that year, and the night shift. So...
The tractor's UNIT number is 8J09B, meaning the tractor was assembled on the 9th September, 1988.
Therefore, if you're certain of both of those numbers, there is a 2 year discrepancy between the engine build date and the tractor assembly date. The engine is likely 2 years older than the tractor. I've never seen that before. Generally the date codes are all within a few months at most, and generally a few weeks of each other. seems to me that somebody installed that engine after it left the factory. It probably is the 5610's engine, but I couldn't tell you that for certain... HTH.

Hmmm. I should have read this before I replied below... Anyhow, that doesn't change what was said.
Best thing would be figure out what you've got.... What that is would be anybody's guess. If it's badged as a 4610 from the factory, and all the numbers match, then you've got me stumped. Something's got to give. It most likely has the 256 cid engine from the 5610. It could have the 268 from the 6610. At a glance, those engines would look the same. Physically, they're the same size. The blocks, head and so on are the same. The difference is simply in the length of the stroke. They have the same bore. If nothing else you could determine the stroke if or when you have problems, and go from there. Also, to the trained ear, one could establish a 256 from a 268. The 268, at torque speed has a sound that only it could produce... that of the crank sounding like it's about to leave the block, but doesn't. They have one of the most foul rotten clangs of any engine I've ever heard. The 256 isn't quite so bad with it's shorter stroke...
The only other thing I can think of would be to take the model number off the information tag, and go to a NH dealer. They should be able to decode that for you. I'm not up on decoding the model numbers... Also, double check that the engine code number (8j6a) is found on the information tag under the hood. They should match. Beyond that, I'm at a loss as to what to tell you....

Rod, i made a mistake on the engine date code. I just rechecked all the numbers.The right engine code number is 8j6a. Sorry for the mistake. Thanks, Curtis

Rod, thank you very much for your help. I think i will try to cross reference some parts , maybe the air filter or oil filter, just to see if it is a 5610 engine. BTW, it has a Ford 7209 FEL on it. It really runs good an seems to have plenty of power. I use it to move hay for my cows. Thanks, Curtis

Curtis,

The engine oil filter and the hydraulic oil filters are the same. The air filter should be different.... Should.... but whoever changed this thing around may or may not have brought the larger air filter from the 5610... so I'd be willing to bet that the standard filter for the 4610 is still in place. Those are the little details you'll need to watch for...

One more ? Would a 5610 or a 6610 engine bolt right up to the 4610 transmission, or would that be changed also. Everything on this tractor fits like a glove. Strange you would mention the noise from the engine.I thought that it was the noisiest diesel engine that i had ever heard. Thanks Curtis

Yes, it should bolt right in like it was always there. Lengthen the hood and any lines and you're off. I'd love to know the origin of this one...
