Something went wrong after Hyd oil change.

[racerboy832]

Just changed all the Fluids on my Deutz Allis 5220 HST. I matched up some filters with the ones that came off the machine ( Yes I know it's a no no). Bought 10 Gallons of Travelers Tractor Premuim Fluid that is for the trans/hydraulics. It says right on is the correct fluid for what my manual calls for. So I dump the old fluid , change everything. Try it out for a couple minutes and seems ok. Next day try it and it goes drives slow, the backhoe has a seperate pump and the PTO will stop when you put a load on it. I switched back to the original filter and it's no better. The one thing I did notice before was that when I pulled the hydraulic pump filter only the amount in the filter would drain. Now when I pulled it, it would keep draining out of the holes around the threaded part. It pumped out about a gallon before I could spin the old filter on. Is it possible the new Fluid it too thin? or did I screw something up with the filters. It was run for a total of about 4 minutes and made no bad sounds.

I'll share a story that will help, perhaps.

I attached a new FEL to my tractor. I was re-filled my hydro with maybe 3 quarts of fluid from TSC. The same premium stuff too that says meets my tractor's specs. I told myself, it was just a top off, what could it hurt? But given my tractor is a sub compact, that 3 quarts was likely 30% of its total volume.

I had squealing, foaming, and a jerky FEL. It wasn't good. I drained everything and re-filled with the SUDT that came from the dealer. Yes, it was a bit more pricey. Immediately, my tractor was back to normal. So, my tractor got a 50 hour service. OK, I can live with that.

If you used generic filters, plus you used generic fluid it is indeed possible your tractor simply does not care them. Seems a stretch, but one never knows. For sure, generic filters can be a crap shoot.

Cannot imagine you harming your machine in 4 minutes. That's barely up to operating temperature. That's the good news, I would think.

The bad news is that you may end up going to your dealer, getting his stuff and trying again.

To reiterate a thread I had going in the MF forum, my hunt club bought a '59 TO35 last year. The tranny/hyd's had water in it due to a dry rotted rubber boot on the shift lever. We drained, flushed, and put in a standard tractor/trans hyd fluid. I think it was GL5 rated that we put in. The lift would not work reliablely or consistently after that. Of course, we had no way of knowing how well/poor it worked before we got it either, since the seller had taken it in on a trade. We later found out what the proper fluid was for that tractor and just a couple weeks ago we finally got around to putting in the proper GL1 mineral based 90wt fluid in it. The three pt lift responded almost immediately by working much better. It still isn't "perfect", but better. Maybe good enough to get us through the mowing and planting this fall. We may yet have to dig into the hyd. system to find out what the real problem is but it was very obvious the correct fluid made a big difference. The GL1 mineral based 90wt oil we put in was much thicker than the tractor/trans fluid we drained out of it, that seems to be the key in our case.

So, maybe you should spend the bucks and get the right stuff and see how that does? You won't know until you try.

I checked in my Manual and it said to you ( Powerfluid 821 ), It says right on the 5 gallon jug that this was the correct match to the fluid. I'm thinking it might be air bound, why else would it keep pushing the fluid out of the filter when it was removed.

I've not yet seen a hydraulic system air bound they all ultimately breath and have a vent somewhere
I'd be surprised if it was air locked

maybe something came loose and is impeeding flow somewhere?
Good luck

also would be good if you could get a meter hooked up to see if there is presure

The part that bothers me is it was fine before I changed the oil. I don't think there is any screens on that one, just the filters, I cut one filter in half to see if there was anything in it and it looked fine.

I find it hard to believe that the oil if it was a ISO standard would have hurt anything. Cross reference filters if right, should not cause that problem either.
I think it was stated a hydro? Might want to check in Deutz Allis forum to see if it is something needed to bleed in hydro. Not really a clue what that tractor has but according to this TractorData.com Deutz-Allis 5220 tractor information you need alot more oil then 10 galons.
Shows 31 galons. I am not sure if that is correct, but may want to double check.

You said: "matched up some filters with those that came off the machine"

matched up how? visual? thread and gasket match?

Did you go to Wixfilters web page and actually look it up? Hastings filters also have a website where you can get a true match up, by the numbers.

Since your tractor is a late 80s early 90s model, is that right?, hard to believe that the the fluid you used wouldn't be suitable, as it likely is better fluid today than the specs of that era. But whether the volume amount is correct and whether you truly used compatible filters remains questionable.

So, you've put the original, old filters back on? Problem remains?

 

[racerboy832]

I can't find a Deutz Allis forum. 7 Gallons came out and went back in, I put the original filters back on and same problem. I'm going to try to open the little bleeders on top of the banjo bolts to see if any air comes out.

i'd be more inclied to think it was a filter issue.

I'd put the correct filters on all over it.. top off oil and run it thru some un laoded paces for a minute or two in case it has air inthe system.. then check the fluid again. look for foaming in the fluid... that's about the only issue a 'wrong' fluid could give you in that short amount of time if the viscosity was at least 'close'.. IMHO.
