Case 1370 Sluggish and Smoking

Just bought a 1370 at auction. Nice shape but blows a lot of black smoke and is sluggish on throttle response. Seems it is missing, not hitting on all cylinders (not certain, but sounds that way). I removed outer air filter no change. I then also removed inner air filter so no filter at all and still no change. Was told it sat in barn for a few years before auction. clogged injectors? Maybe that's the cause of missing? Weak turbo? Maybe cause of black smoke? Could have had pump turned up, I don't know, nobody at auction knew history of it. Very nice tractor otherwise, would like to get it field ready soon. Oh, also seems it has a bad exhaust gasket on one cylinder. Going to take hood off tomorrow and investigate further. Appreciate all the help meanwhile and will post more info as I have it. Thanks!

Thanks all for the solid advice. I went over to my dad's place to fire it up today and check exhaust temps at each cylinder, but it wouldn't fire up. Pretty cold here today, and I had no ether. Will get some and try tomorrow morning.

Found today though that it has a coolant leak up front in addition to a pretty big oil leak up top. Think it's time to pull the hood off this week and get a better look at what sort of fix up job I'm looking at.

Debating about doing a major overhaul on it. Moved 2100 miles this summer to get back to family farm and the idea was to use grandpa's 1370 as my primary tillage tractor. Got here and found it had a twisted shaft (we think) in front of tranny, and haven't fixed it yet, but found a deal at auction on another so that's what I just bought. I have extensive experience with gas engines of all sizes but next to none with turbo diesels, or diesels at all. But learning, reading, experimenting, and will get on top of it!

Thanks all for the advice! I'll do some digging and poking over next couple days trying your suggestions and will post what I figure out when I have more news! I travel back west late this week so might be the week after this one before I get too far into this, but looking forward to tearing into it!

Sounds like a very exciting time for you.How many hours does your 1370 have?I would figure out the excessive smoke and miss problem then see how she runs.Those 504s are pretty tuff motors.Be a good idea to change trans and hydralic oil and filters.Two 1370's will be able to get a lot of work done.Hope all goes well for you.

I have seen this happen a handfull of times with tractors that have not run for a few years. If there has been a little water in the system when sitting the nozzle tips will get sticky. Then when they open for the firt time in a long while they will stick in the open possition. This will cause a hard start, black- gray smoke, bad throttle response. Crack a fuel line, if the smoke clears you have found the bad guy. I would pull the nozzles and have someone who knows what they are doing clean them. Dont let anyone tell you they are junk, just clean and reset them. I usally get about $20.00 a piece to do this. If no one in your area wants to help you give me a call. 231/757/0064

Thanks Al, that does seem like a real possibility here. I'm contemplating a major overhaul so I have a very reliable tractor next year, but whether I do that or not, I'm thinking after sitting it may be smart to pull and recondition injectors either way.

Had an 870 with the same problem over the summer ended up being the injectors. One shot two others would not hold pressure and where leaking before they popped off. Try filters first and see if that helps, got new injectors from abilene machine for $180.00 for the four them cured the problem.

Thanks Eddie, I'm thinking that based on your reply and some others that I may be pulling and reconditioning the injectors almost regardless since it has been sitting for a while. Symptoms do point to just fuel pouring in since removing all filters and running intake wide open doesn't change a thing.

Exhaust leak is surely hurting turbo performance but it is pouring smoke even at idle. And engine sounds like one cylinder not firing. Sounding a whole lot like injectors the more I read, get advice from you guys, and put the thing between my ears to work ;-).

You should also add some Diesel Fuel treatment. Power plus.

Yes, thanks, after sitting for a while and not sure how much they really siphoned out before adding new fuel, and probably some old fuel still in pump and filters, will definitely do this. Good idea.

As AGC said check the air intake. If the tractor sat in a barn for a few years it might have a birds nest there. Also get the old fuel replaced with new fuel and replace the filters. An exhaust leak will lose turbo boost.

Thanks Eagle Doc, As I just mentioned in another reply I eliminated the chance of air restriction by removing all filters and the cover, cleaning out the air box carefully before re-firing, and with completely open air intake problem was no different. The old fuel could be part of the problem but after a few hours of running and them saying they siphoned the old out it should be in the clear now, but that's still a potential problem since room for error there and not THAT much running on it yet. I'm certain of the exhaust leak, and yeah that makes sense it'd not run the turbo as hard and could be part of the problem, thanks.

You are right about the air cleaner. By the time I got my post typed I was not thinking about that. Everyone here is giving you good advice. I am grasping at straws here but check the muffler for obstructions. After sitting for years who knows what could have happened.

P.S. I am sorry you have to read this so slowly - I can't type very fast. Hehe

Dirty fuel filters will do the same thing. Lottsa smoke and no power.

I hadn't heard this before. I believe I have new filters for it, as I also recently bought my grandpa's old 1370 and got some things with it, so I'll try that if I have them or get new ones if I don't. Best to change out all filters for sure anyway not knowing history or how long they've been on there. Thanks!

BTW, I now have two 1370s, a his/her collection! ;-)

Check the aspiroator intake in the fron.t above the radiator. they were known to get cloged up with corn chaff and such and restrict the inlet air flow.

Thanks Case guy, I ran it with all air filters removed and the screw-on cover over the filters removed, to where there couldn't have been an air obstruction. I certainly cleaned out the filter box well with a vacuum first to make sure the engine couldn't suck in anything bad first. But all said and done, this made zero difference. It isn't an air obstruction.

For starters tomorrow when you start it imediately check each exhaust outlet for heat with fingers!! Any of them not showing heat after while of running indicates that cyl might not be firing..Fingers are a a poor mans infred thermometer.

I thought about that when I got it home tonight, but unfortunately that was after a 2.5 hour drive! Will do that in morning when I fire it up. I assume if not firing that the most likely culprit is a plugged injector?

Make sure the shaft in the turbo is not broke. I had the same symptoms once and just replaced the turbo with a used one.

I'll check the turbo over but I think it is at least operating OK, meaning I can hear it kick in and see a change in the smoke.
