pt756 Posted June 24 Share Posted June 24 Hello there, so our overhaul on the 310 made it about 100 hours, kind of disappointed as we did everything to the engine, no shortcuts, so first time i have had such a bad time with an overhaul, so the tractor now has a hole in the side of the block this happened while cultivating corn, so now the engine is done, at the time we were thinking about the overhaul we or the the repair guy suggested putting in a 360, I kind of wanted it to be original so we did the overhaul, was always wondering about the single oring and the problems with pumps in the future, so now we try and find block which i understand are hard to come by or consider something different, thanks for any help, Quote Link to comment Share on other sites More sharing options...
axial_al Posted June 24 Share Posted June 24 Were it me I think I would consider a B cummins. Â Should be able to find one easier than a 360 and based on the one in my mx120, they are a really good engine with good parts support. Â Or what about a 358 from a combine? Â Good luck.

HydroTek Posted June 24 Share Posted June 24 DT-360 truck engine would be my choice -- the turbo makes that little engine or a D358 Quote Link to comment Share on other sites More sharing options...
Super A_sepa Posted June 24 Share Posted June 24 As said, the turbo really makes the 360 run.   A Cummins makes a pretty nice conversion, the big parts are fairly simple but the little details that make it nice add up and take time. But they definitely help the fit and function of the end product. The Cummins will be the easiest to find I would think. Quote Link to comment Share on other sites More sharing options...
7and8and1456 Posted June 24 Share Posted June 24 What happened to cause the engine failure? Quote Link to comment Share on other sites More sharing options...
Michigan No Till Posted June 24 Share Posted June 24 Been following sad to hear. Always concerned about the German with M&W in the 756! Have not a clue for you, just a bummer.. Quote Link to comment Share on other sites More sharing options...
Matt Kirsch Posted June 25 Share Posted June 25 So are you talking about the D360 American or a D358 which is the larger displacement version of the D310? Either one is going to be a challenge to find. It's not 1985 anymore and there's just not lots filled with used-up late 715 and 815 combines ready to give up their fresh German diesels to waiting tractors. D360 was only used in the 766 and early 886. DT360 was used in trucks until 1989 IIRC but nowhere near as common as 400 series. We had a DT360 conversion done on the 756 around 20 years ago. The engine came out of a bus and was converted by a retired classic IH mechanic. There were some significant challenges to overcome due to lack of parts availability then. There are only fewer parts tractors to pull from now. Quote Link to comment Share on other sites More sharing options...
pt756 Posted June 25 Author Share Posted June 25 we have had tractors overhauled by this guy and other repair guys, never have had issues, I dont know that much about the inside of an engine but different theories, one guy said must of been a plugged passage ?? dont know, i am close to 67, figured we had the tractor for 40 years never an engine problem, so I figured lets do it right, always appreciate all the input from the responders, at least now we dont have to wonder how long its going to last, the repair guy does have a 360 from a bus or truck, knows what we needed back then, something from a 312 I think and something from a 414, havent talked to him yet. we just towed it down there last night, and parked in his yard, I am sure when he got home from his stock car racing he drove right by it, I did see a 706 on craiglist with a 414 in, that probably would be more of a challenge, I did know when we thought we needed a crankshaft the first time I started calling around, doesnt seem to be a lot of parts for the 310, We really like the tractor, planting corn, cultivating, making hay, unloading wagons, nice handy tractor, Quote Link to comment Share on other sites More sharing options...
Super A_sepa Posted June 25 Share Posted June 25 The big frame front cover can be cut down to fit the frame rails without finding the 312 front cover, and then just uses one bolt instead of two. I think Ed was getting some trimmed and drilled and tapped for the second hole as an exchange deal at least at one point.  He would have the adapter plate to match the bellhousing without a cavity. On the two 300 series I swapped in I decided the cavity didn't bother me and used a trimmed down regular 400 series back plate.  You will also need spacers between the frame rail and the back plate to keep the hood holes correct. The German back plate is thicker then the 400 series. Ed had them when I did mine. 1 Quote Link to comment Share on other sites More sharing options...
Jacka Posted June 25 Share Posted June 25 756's are pretty rare in my area.I know of one close by,really nice tractor.Narrow front,diesel runs nice,painted and used to plant corn,mow etc.He has other all red tractors but that is my favorite.Its just a sweet little tractor. Quote Link to comment Share on other sites More sharing options...
stronger800 Posted June 25 Share Posted June 25 414-466 would have to be easier to do. And easier to get parts for in the future. Quote Link to comment Share on other sites More sharing options...

And easier to get parts for in the future. 400 series block height makes it more of a challenge in a 7 because the hood is an inch or two shorter. Gets a lot tighter under the fuel tank. Guys have done it but I'm not sure if they cut the front off the tank or removed the heat shield or what. Yes parts would be easier to find in the future on one though.  I really like keeping things IH but that would be a benefit to a 5.9 swap. Small enough to fit the shorter hood height and plentiful.

pt756 Posted June 25 Author Share Posted June 25 question would a 5.9 be a non turbo and what would be the horsepower, I have seen them in my area, mostly on olivers, or whites and an allis, Quote Link to comment Share on other sites More sharing options...
stronger800 Posted June 25 Share Posted June 25 Non turbo?   Such a strange term Quote Link to comment Share on other sites More sharing options...
stronger800 Posted June 25 Share Posted June 25 Is there a convenient way to run the original IH tachometer off of that engine these days? I know somebody had posted they had used a alternator drive. Quote Link to comment Share on other sites More sharing options...
pt756 Posted June 25 Author Share Posted June 25 was thinking always thought I wanted a 5230 now we would have that in a non turbo version with out all the electrical problems that can happen? Quote Link to comment Share on other sites More sharing options...
Super A_sepa Posted June 25 Share Posted June 25 I'd prefer to have a turbo on either motor but a non turbo might be a little easier. Yes the IH tach can be made to function and read correctly with the Cummins motor. Jesse at Restoration Tractor Sales can set you up with the parts or Ed Leaman as well. I think you could get 120 hp out of a non turbo motor but I think that was about as far as we were pushing them. Quote Link to comment Share on other sites More sharing options...

I would opine that 120hp  would be really stretching for a non turbo 5.9.  A 5230 is already smoking some at its factory 85 hp rating.  At least ours is.  Maybe with a real injector pump instead of that Lucas garbage it would do better.  2 hours ago, pt756 said: was thinking always thought I wanted a 5230 Get a synchro 5130 or 5230 and you have have a really nice tractor, much nicer to drive than a 756, with not that much electronics to go wrong.  Quote Link to comment Share on other sites More sharing options...
stronger800 Posted June 25 Share Posted June 25 I think our mx110 was a 5.9 right?  Turbo….burned more fuel than it made power (110?) but it was comfortable for loader work Quote Link to comment Share on other sites More sharing options...
Matt Kirsch Posted June 25 Share Posted June 25 120 out of a D360 I think is doable. I would not be surprised if my 756 with the DT360 bus engine turbo delete dynoed at 100HP or more. It will push at idle where you would have to have the old gas engine running wide open. Yup, DT360 turbo delete. Bet you've never heart that term before either. We decided to delete the turbo to make fitting it in the tractor simpler. We really didn't know how to make the turbo work with off-the-shelf parts at the time, and keep it tucked under the hood. 120 out of a 6B Cummins... I dunno. Dad chose the 5220 instead of the 5230 because rumor had it the 5220 with the 4BT had more usable power than the 5230. Of course don't let the 4BT get below 1500RPM because it falls on its face.

Super A_sepa Posted June 25 Share Posted June 25 I've heard that about the 5220 vs the 5230 as well. I would agree. There was a 5120 through the shop a bit ago that was early enough it also had an intercooler. That was a neat little package. The 120 figure might be high. It's been close to 3 years I'd guess since we put a Cummins in something and very few of the ones we did were non turbo but I was pretty sure we did one. I might be wrong.

Gearclash Posted June 25 Share Posted June 25 28 minutes ago, Matt Kirsch said: 120 out of a D360 I think is doable. About as doable as it would be with a 5.9.  I spent plenty time on a turned up 766 with the stock D360.  Back in those days it smoked like a offended volcano if pulled down well into overload.  I doubt it made over 100 hp, 90-95 would be more realistic.  Adding more fuel would have just made that much more smoke and very little more power.  The 1066/DT414  we had would comfortably out pull it, but not by some wild margin. Quote Link to comment Share on other sites More sharing options...
ksfarmdude Posted June 25 Share Posted June 25 I'd be checking the old engine out with a fine tooth comb as to why it put daylight thru the side 1 Quote Link to comment Share on other sites More sharing options...
pt756 Posted June 26 Author Share Posted June 26 Another question, is the 312 the same physical size as the 360, would the 312 fit in there better? I wouldnt mind something better, a 2 wheel drive 5230 0r 40, I understand the electrical gremlins are better than the 51 series, problem is the 756 is in great shape except for the motor, hydraulic assist, park brake redone, pto redone a few years ago and only used to unload wagons or siderake, shifting cover has been redone, new rims, tires , weights, 3 point , nice set of fenders still a nice tight tractor except for the motor, Quote Link to comment Share on other sites More sharing options...
acem Posted June 26 Share Posted June 26 I might be able to get you an engine or at least the parts. If you like I can check. Thx-Ace Quote Link to comment Share on other sites More sharing options...
