Thanks c farm. It's exciting. It's my first big piece of machinery.

That looks like a deep bucket. Sure was not used to dig rocks with. ;D

It's definitely a big bucket, it needs a bit of work, rusting away in spots, still lots of integrity though, I filled it with stones to fill parts to the woods road so far.

I am needing to do a few hydraulic fitting repairs. It seems fluid from there on the 3 pt and one side of the front end loader. Hopefully just o rings

mike_belben · June 20, 2021, 03:58:21 PM

On SAE fittings it probably is just the O ring.

The drain plugs for the hydraulic rear end and trans oil are in the bottom. Think I had to take about 4 plugs to get it all out of my 986. And the replacement oil from Case is Hy-Tran, for hydraulic transmission fluid. I bought my oil from NAPA this spring, they have a yearly oil and filter sale. You can also use HG fluid from Phillips 66, many other oils, think the cheap oil from some farm supply stores has been sued out of business, got a check from some law firm for 20 bucks from some oil I bought at Orsheln supply to put in my log splitter. Change the filters as well. If you have a Case dealer nearby, they could show you what filters to change, if they are any good. Went to my Case dealer one time, asked to see the repair manual on my skidsteer, which I bought from them, they would not let me see it. Haven't bought any more case equipment either.

Thanks for the info. Nearest dealer is 3 hours away unfortunately. Napa it is. Hopefully they have the hydraulic o rings too. How can they not. Small town Napa store though lol

For motorcycles and atvs incan usually find a free pdf version service manual but I can't seem to find one for this tractor, I may cave and spend the 30$ for one

HemlockKing · June 20, 2021, 04:51:02 PM

Well I must say, the yellow jackets love the tractor. It was a battle all day with them lol

mike_belben · June 20, 2021, 11:17:09 PM

Dont get raked over coals on the O rings.. Nothing special. I got charged $13 each on 2 itty bitty generics at case a few year ago. Coulda bought 1000pcs of the same chicom generics @ HF for that. Ive used the HF junk on many many hydraulic parts over the years without issue.

What is the abbreviation HF?

Harbor Freight. A cheap place to buy tools. Some of the tools are cheap and will break with hard usage, but some OK for only a year usage. I buy black electrical tape and the steel cutting blades for a saw. A great place to buy cotter pins too.

Our place of cheap tools is Canadian tire. No HF here. Or princess auto which is my usual

Got some cross threading action going on here seems to be a culprit too. I assume they sell these fittings at part stores?

mike_belben · June 21, 2021, 08:39:44 PM

Standard plumbing. National pipe thread. Unless its on the exhaust side i suggest you use sched 80 or higher. Sch 40 pressure rating isnt terribly high.

The bottom is probably a male SAE O ring to NPT female adapter.

Looking to change the hydraulic fluid. I can't find a service manual. Is this the drain plug for the hydraulic? And I understand this uses "hy-trans" fluid? I assume the power steering is powered by that too? Thanks anyone who can help .

Not the drain plug. The fill plug for the entire hydraulic system is the pipe plug in the picture. If you want to drain the entire system you will have to drain all the case drains on the bottom of every case except the engine of course. Yes the hydraulic oil used is Hy Tran and you can check hydraulic oil level with the dipstick along the main case right by where you feet are placed while sitting on the seat.
I would assume you have the D-179 engine which is a 3 cylinder engine. IH did also make a 4 cylinder diesel engine that also fits in that frame so I'm not sure which diesel engine you have.

Is there a specific brand or grade I should use or do I just go to a tractor supply store and say "I need hy trans oil" ? Yes I was aware of the dipstick and fill location, I've been checking it before working it as it's been leaking. I'm reading this takes around 9 gallons of hy trans. I suppose I'll be needing to make a round trip to the tractor store. I'm not even sure which engine oil it would take, rotella t4?

farmfromkansas · June 23, 2021, 01:12:09 PM

Be better to go to NAPA than TSC for your hydraulic oil. And the Rotella will work for engine oil, or just ask the guys at NAPA. Be sure to change your hydraulic filter. There is a filter on the engine for coolant, change that as well, helps to protect your engine from electralysis.

HemlockKing · June 23, 2021, 01:23:34 PM

I need a couple hydraulic hoses too I'm thinking so I'll half to call if Napa sells those I'm not even sure. A few the rubber is sun baked and cracked although not leaking, I still wanna get anything that might need fixing in the near future, fixed. There is also a loader arm pin I need as someone has just used a grade 8 5/8 bolt on one side. It appears all the pivot points have not been greased in god knows how long. The bucket is rusting through just before the edge so I may need to cut some of the bucket out and replace or just have it shorter since massive anyway. The insert at one of the bucket cylinders is leaking too and it appears someone put some kind of silicone sealant on the threads because they were battling leaking, I hope the cylinder doesn't need replacing. Also another leak close but it's a fitting so I think that isn't a big deal, a leak from the power steering too, hopefully hose or fitting related and not seal.

Welcome to the old iron club.

Thomasjw4 · June 23, 2021, 08:13:44 PM

I feel your pain on the old IH's. I rebuilt a 384 this winter and am still tracking down fuel issues.

I just said to my son today... When something breaks literally every single day that you get out of bed, youve got enough equipment.

Like others said the drain plugs are on the bottom of the gearboxes. The square pipe plug in the upper left corner of your picture is the hydraulic fill. Like Gary C said the dipstick should be behind your left heal along side the gearbox and the left running board. What you're finger is on in the picture should look like a brake bleeder and that is exactly what it is. Each side has one for each brake. I have a 574 gas with Dunham loader. Been a great tractor but the diesel would be much better. They had a D-239 4 cylinder in them. The power steering works off of the hydraulic system as do the brakes. There is a process for bleeding the brakes requiring you to pinch off a rubber return line in what they call the "keep fill line". Not a bad job once you've done it a few times. Don't ask me how I know this. Don't ever forget to release the parking brake before driving away. It will burn and leave burnt particles in the hydraulic fluid and plug the hydraulic filter. Don't ask how I know this either. These tractor like clean Hy-Tran and filters.
More questions, just ask. Lots of knowledge base here on the forum and all willing to help.
Here's a pic of my 574.
