International 2504 with D188 diesel

I'm looking at a project tractor it is an older International 2504 which is a 504 (Farmall) but the industrial version and not a row crop tractor. It has a loader and 6 ft trencher on it. Been sitting a while and the owner says he got it off a guy who ran it out of fuel and never was able to get it running again. Has a Roosa-Master pump on it and is complete. Old style injectors with a prechamber from what I can determine. You can get an entire kit for around $800 for the engine so I'm thinking it over. Anyone work on this older engine anything I should look for? The trencher and loader are of interest. The hour meter shows 2815 on the clock. It's an older unit but parts are available and other than missing a fender and seat is all there. The trencher is an Auburn brand out of Nebraska but again it's from the 60's.

Thanks!

Don't know about the tractor itself but that was a pretty good little engine. The pump is an easy rebuild and not very expensive to work with. Auburn trenchers were fairly common around here and don't use any proprietary parts so any good farm supply outlet will be able to supply most of what it may require.

The question I seek an answer for is simply; why, or why not?

I think it just found itself in the hands of some guys who don't know much about fuel injection. Uncertain how long it's been setting but if I can get it south of $1500 I think its a decent deal. Unfortunately I couldn't get at it today to determine if its stuck. I figure worse case a pump rebuild and engine rebuild. The injectors are very simple. Claims they loaned it out and the guy ran it out of fuel then they were never able to get it running again so it got parked.

Some of the older "Roosa-Master" pumps had a small filter element in the fuel supply inlet to the transfer pump located in the rear of the pump. Check that first to ensure it's not plugged if it exists. Of course change any external fuel filters also.

As you mentioned first ensure the engine is not frozen from sitting. That D-188 engine was used in a lot of implements, not just tractors. I seen quite a few on irrigation pumps, balers, tub grinders, etc. Pretty good staring if the batteries were kept up.

The question I seek an answer for is simply; why, or why not?

Found this on a red tractor forum.

"One simple thing to check is the return line from the diesel injector pump to the fuel tank. If that is clogged, it will shut down the primary lift pump valve and consequently the fuel to the main injector pump. my suggestion- pull off the return right at the injector pump and blow into it. If your tank bubbles freely your all set. If it does not the little valve in there is stuck closed. To verify: run a free flowing hose from the injector pump return into the fuel tank, prime the injectors the normal way and then try to start it. if that doesn't work, you might want to pull an injector and see if fuel is getting into the precumb chamber"

I'm not familiar with the return line plugging myself. The pressure/check valve mentioned could be stuck from setting without fuel, or dried fuel of setting several years.

I'm thinking why it's mentioned the return line is plugged the transfer pump pressure will not be greater than pressure built up in the return line and the pump will no longer move fluid. Again, I've not seen this myself but rather a no start, or weak power in a Roosa-Master is usually a pressure roller has fractured, a transfer pump vane has broken, or a fuel restriction someplace.

Most pump shops charge less than $1000 for a complete rebuild of the pump and four injectors around here so not too bad to just have rebuilt to know what you have at the start. Plenty of salvage yards around so shouldn't be too difficult to round up the missing items needed.

Is that loader an IH original, or vendored unit? Being and industrial tractor I'd wager a vendored unit which will be much heavier built than an IH unit. Is the PTO live?

The question I seek an answer for is simply; why, or why not?

IH loader not 100% on the PTO but it should be. The auburn uses a hydraulic system to creep the tractor while trenching so the transmission is in gear but it has a hand clutch with lock to keep the transmission and clutch from engaging. PM you the listing.

Remember that hand clutch well. Don't use it for anything except trenching as it won't hold up to anything else very long. Those were some heavy tractors for their time and did the task asked of them. I do remember seeing a few looking like them but was too young in those days to know much.
