Question for those who know about hydraulic cylinders.
I have a Nortrac NT254 with an Ameriquip 1836 NT700 front end loader. While pulling posts the other day, the wife is pointing at the lifting cylinder on the left side. There was a “Hair fine” stream of hydraulic fluid squirting out the cylinder casing. There evidently, a pin hole in the casing on the end opposite the cylinder rod. I couldn’t see it very well, but in or close to the end of the cylinder case itself where the “TEE” is attached to the case. I suppose that cylinder case has the end welded onto the tube, and perhaps this weld has a small pin hole.
How does one fix this? Can it be welded, and if so does it have to be taken off and drained, or can it be epoxyed? (I am stupid about this and just trying to get educated.) Would it be simpler to just replace the cylinder, and if so does it have to be done in pairs?
Your thoughts and experience would be welcome.Thanks all.

OK, Maybe I am making this difficult. Checking to see what a new cylinder would cost. Called Nortrac, said it was a 2 inch bore. (Measures about 2.5 inches outside diameter of the casing) Didn’t know the stroke. So I lowered the bucket loader, as far as it would go (lifted the front end off the ground). From pin center to pin center measured 30.5 inches. Elevated bucket to as high as it would go, pin to pin measured 52.5 inches. So is the stroke 22 inches? If so, I can’t find a cylinder exactly like that. I see retracted lengths of 28″ and 32″ with strokes of 20″and 24″ respectively. Does it have to be more exact than that?

Does it have to be more exact than that?
Absolutely. The cylinders must have the same bore, stroke, and displacement (rod size). Otherwise there will be a whole lot of twistin’ goin’ on.
If Northern can’t supply the correct cylinder, then you may have to purchase two new ones to match.

Yeah I had checked the surplus center. I did find Some made by Magistar Hydraulics that is pretty close. The tube ends widths I would have to measure. Maybe they could be ground narrower if they won’t fit. http://www.ebay.com/itm/Hydraulic-Cylinder-Welded-Double-Acting-2-Bore-22-Stroke-Cross-Tube-2×22-NEW-/331906968612

I recieved a parts manual from Ameriquip and thought I would post it here for posterity. Kind of neat in that it lists the specs for the cylinders. Called a place referred to by Ameriquip, and the cylinder with the part number that I need was quoted at $463. OOOOOUUUUCCCCHHHH!!!!!!!!
I said I’ll look for alternatives.It is a “tang: fitment on the base end. I suppose that is a stronger end.

Have you looked into getting yours repaired?
Yes, exactly. Any welding shop could do it. Probably would take all of fifteen minutes. Although you should disassemble it first.

OK probably get blasted for this but…
You guys got my courage up about how easy it was to take these apart. Did some reading and this was actually a pretty easy fix. I think I got it as I don’t see any oozing, runs, or oil residue when I have the loader raised.What I did, was disconnect the hose closest to the base. Unpinned the base end from its mount. Extended the cylinder piston, (to pull the workings away from the base end). Sanded the area, cleaned with brake fluid many times. Then welded the spot. Had to do it twice because I must have missed the spot the first time. I filed the weld down. I haven’t been able to knock the weld spot off. I guess I will see if she holds. Not out anything except a little labor.
