How difficult in frame rebuild?

My brother in law has an International 866. We've found that it has a slowwwwwwwwwwwwwwwwwwwww leak of coolant into the oil pan. My understanding is, this can mean a cracked head or perhaps a bad seal on the sleeves.

I've done nothing yet to try to dig further into it. I WILL add that last fall when this was discovered, we changed fluids and watched it... I was able to cut SEVERAL fields with absolutely ZERO indicaction of any loss of coolant.

Today, with the tractor having sat idle since maybe November, I now see my coolant is lower and my oil is higher.

I am going to change fluids again and keep eye on it as i cut a field BUT... I'm trying to get educated on doing a resleeve job.

I'm not a mechanic BUT I am very mechanically inclined... probably already have all the tools I'd need unless there is a special tool needed to pull the sleeve.

Is this something a backyard mechanic can do (under the presumption a re-sleeve will in fact, cure the problem)

If it's not the sleeve then that might suggest it's a cracked head? I'm presuming I'll have to have the heads off anyway so that might just be a good time to send it out to be checked. (?)

I've never done this... I'm not intimidated by it at all... engine is pretty easy to get to... I've got an industrial backhoe (mine) that I can use if I need to hoist anything.

Heck...to tell the truth, I thought about yanking the entire engine out and putting it on a stand so I could redo the entire engine... then keep realizing it's not MY machine to spend money on!!

Hi. The first thing I would do is: - Remove the radiator cap and top the coolant right up. Now with the engine running fairly fast watch for bubbles in the coolant. If you have bubbles then its 90% chance that its only a head gasket. After that start thinking about more difficult and expensive problems. MTF

I am thinking you mean 886, which probably means it has the D358 engine. I would think it is also a possibility that the oil cooler may have gotten a tiny rust hole in it allowing coolant into the oil.

Oh and the two engines offered in the 886 were both wet sleeve engines so it is also a possiblitly that the liner o-rings could have started leaking, especially when it sets around.

Coytee: Assuming it is a 886 rather than a 866, you've got a wet sleeve engine, and very likely you have cavitation on the sleeves. I'm betting the crank will have to be turned. Your damn lucky if it doesn't need turning.

It's not a backyard job, I smell disaster. It might be for a top notch engine rebuilder, but he wouldn't do it in the back yard, too much dust. I patronized an engine rebuilder over the years, he wouldn't even let any visitors in his shop while putting an engine together. He said people milling about created too much dust. I know his work gave him one hell of a good reputation.

if engine isn't overheating or blowing coolant out of overflow,pull oil cooler an check it if no problem is found remove oil pan then look around the bottom of liners after engine has been sitting for a reasonable amount of time if no leak is found hook a radiator pressure pump up to radiator an pressurize it an check again

YOU CAN PULL THE OIL PAN AND LOOK UP AROUND EACH SLEEVE/LINER AND WATCH FOR COOLANT SEEPING PAST THE LINER PACKING RINGS.YOU MAY NEED TO PUT PRESSURE TESTER ON THE RADIATOR.AND,LIKE HUGH SAID,YOU WANT TO WORK IN A CLEAN SHOP.

I do think it's an 886...sorry for that...

regarding the oil cooler... is that the ...how to say "torpedo" looking thing on the side of the engine? I do not see anything that looks like a traditional cooler (radiator) however, there is this cylinder on the side of the engine that has some mounts to it... looking much like how the exhaust manifold might attach, where it attaches. In other words, as i recall, it's not got a little copper tube going into it but a very strong engine mounted attachment point. I THINK it was on the 'passenger side' of the engine.

Would that be the oil cooler and if not...where would it be?

I didn't think about having the crank turned I was hoping I could resleeve it and move on with life.

Is this the oil cooler and if not....can someone tell me what the three circled items are?

You can go to the CaseIH website and do a search for parts to find parts listings and diagrams.

Yes, the item you have circled is the oil cooler, and your engine is the D360 instead of the D358. It is fairly common for those oil coolers to fail and leak coolant into the oil. The good news is, the D360 is less likely to cavitate than the D358, bur it is still possible just not as likely. I would start with the oil cooler, and work from there. It is fairly easy to remove and you should be able to pressure test it without too much work. I would not be scared to rebuild that engine in any home garage, just don't roll the parts around in kitty litter or anything. I have rebuilt numerous tractor and vehicles engine right in my garage and have never had a problem with any of them. Just keep them clean and take precautions not to scar any parts when reassembling.

To pressure test it, would I need to remove it and take it to a radiator type repair shop?? How might I do that myself?

If in fact, this cooler is the culpret, would I simply replace it or is that something a radiator type shop can weld/solder/recore like an auto radiator??

I'm more optimistic with the comment about D360 vs D358!! but I will still not get my hopes up until problem is verified!!

Thanks for your guidance thus far

I might add that upon looking at the picture a little closer, it almost looks like the right side where the two 1" tubes connect... they simply slip into each other? Meaning, it doesn't look like it would seal at all and there are no clamps visible.

On the rear of the unit, it bolts to the engine block and has what appears to be an "exhaust manifold" type mounting point so I can easily see that being an oil input/output location... the front of this thing however, really screws with my brain as to what all needs to come off. I'm HOPING it's only the part that looks like a muffler and not the red part in front of it.

Guess time, couple wrenches and a handful of bloody knuckles will tell!! :roll:

That is diffenitly a D360. It is NOT a 358. I have an 886 with 4165 hrs. I would check the oil coolier first. That is most likly ur problem.

I have a couple of steel plates that bolt on the cooler where it would attach to the block. One plate has a hole where I can attach an air hose. While pressurized, I stand it on end and fill it with water. Watch for any bubbles.

Most likely the oil cooler is not your problem. Cooler failures almost always result in oil entering the coolant. Often the first indication is oil coming out of the Radiator.

Well... Jed Clampet I'm not... That's too bad...I would have liked to have found a gusher of oil!!
