3 or 4 cylinder diesel engine

[HBR]

I've been searching the bone yard for parts, I was told that my tractor is a 3 cylinder diesel Ford 4000. At the bone yard I found an older Ford tractor that I thought may have the same engine. But the guy who was helping me said it was a 4 cylinder diesel, not a 3....how can I tell the difference between a 3 or 4 cylinder diesel engine?

One way is to look for the exhaust manifold, Are three pipes exiting the engine or four, Each cylinder will have it's own exhaust pipe.

4 cylinder Ford 4000 has the intake on the left; 3 cylinder Ford intake is on the right (crossflow cylinder head). Or count high pressure lines leaving the injector pump.

Looks like both tractors are 4 cyl. diesels...

That's a 4 cyl as stated, pre-65 like my '63 2000D. My '65 3000D is 3 cyl. Both are smooth operating and really have no preference. However when I bought my Branson I did want the 4 cylinders. Funny on engine technology. I had a 1979 or thereabouts 3 cyl Ford 4600D at 200 cu in and 1800 PTO speed putting out about 40-45 hp. My Branson has a Cummins 200 cu in and is brake rated at 65 built in '07. Ha, just dawned on me the extra rpms are the source of the additional hp so I guess there isn't all that much new rocket science after all for naturally aspired, direct injected engines. Just ran the ratio of 1800 to 2600 and it's right on the HP number differences.

I've had zero problems with my 4 cyl and at 3600 hours it's still a pony. Had to replace the water pump recently and a starter year or so ago. Have some leaks but no big deal. Best I can tell the tractor is all original and no major surgery. Good tractor. I had to overhaul the 3 cyl but that wasn't the tractor's fault. PO abused the heck out of that machine.

Edit: On bone yard picking, you need to know if the engine is out of the same tractor since the cubic inches and HP of the 4 cyl 2000 and 4 cyl 4000 are different. As I recall the cubes of the 2000 are 136 and puts out about 30 hp and the 4000 cubes are 178 putting out around 40 hp at 1800 PTO rated (540) rpm. On telling the difference in just looking at the engine Soundguy can probably put you onto that.

Thanks for all the information, here are pics of my engine:

A 1979 4600 would be rated at 52 PTO HP, but at 2200 ERPM. Using commonly accepted percentages of parasitic loss, that's pretty close to 65 gross engine HP which is essentially the same as "brake HP". not very different from the Cummins rating in the Branson.

Thanks for the info. Makes sense. The Cummins is rated at 57 PTO and that plus the rpm difference makes the numbers match. Speaks well for the old Ford technology which I thought was pretty bullet proof as it was. I've had 5 over the years, 2 were 4000, 4 cyl. Probably where I got my numbers jumbled up.

I have a 3 cylinder Shibauru Engine on My Ford CM 222 Commercial Mower. after cleaning the fuel filter etc and primiing the fuel system via the little 10 mm bolt on the injector pump. Every thing was going fine. I loosened the bolt, air came out. then diesel then it started right up. The Problem NOW, When tightening the little bolt back down. It apparently was stripped. on the last few threads and would not seat. I had a new bolt of the same size in My barn . I replaced the bolt,, It threaded down but it still leaks. There is a rubber washer that seems to leak and wont fully compress. I am new to this engine and will proceed with getting a new bolt or two and some washers. Does anyone have any insight and familiarity with this Engine and this problem? Thank You.

Might do better if you start a thread on this instead of posting take some pics and get info if one is available try dealer or diesel pump repair shop. good luck
