need metric hydraulic cylinder for AC3 backhoe

[texasjohn]

Bought a 3ph backhoe off Craig's List, AC3 is the decal on it...absolutely no other markings. Fits a 50ish HP tractor.

Swing hydraulic cylinder is busted...cracked gland.
No sign of manufacturer or other markings on this cylinder or any other.

Took cylinder to local hydraulic shop... full service shop, good people, I trust them. They said that it is a METRIC cylinder and that they have no sources for metric parts....go back to the OEM...but I can't figure out who the OEM is.

I have no problem with purchasing a new cylinder...but it needs to be METRIC because the hose fittings are metric as are the pins holding it in place.

Have looked all over the net for metric hydraulic cylinder suppliers and/or parts. No luck.

Have called numerous hydraulic repair places in Austin and Houston...all say that their only idea is to have a new gland machined to order.

Surely I'm missing something simple here...

Photo of the cylinder would not be useful...it is a simple red cylinder with no markings on it... pins hold each end in place.

Does anybody know where METRIC hydraulic cylinders and/or repair parts can be obtained, I hope

How about getting a regular cylinder, get adapters to go from metric to whatever on the hydraulic hoses, and have new pins machined. The pins could get tricky; but I would think it's doable. Or get bushings made to fit the space between the metric pin sleeve and the inch system pin.

Possibly try one on the Chinese tractor dealers that advertise here on TBN, they sell backhoes made overseas and may be able to help you.

You do not say what repairs are needed. A simple rebuild of just o-rings would be easy so i assume it is something else?

Sorry, missed the cracked gland.

I'd head back to that full service hyd shop and have em build or modify an existing new cylinder to work.

Did you ask if they could make you one? Was the barrel damaged too? Most glands are pretty simple. Shop I work at used to do a lot of hydraulic cylinder work (mostly big coal mining equipment cylinders and a lot of it metric). Still do some but we no longer chrome plate and don't pursue that line of work much. We've made lots of glands, piston, rods, etc. Even complete cylinders from scratch. Having one made should be an option.

All parts apparently undamaged except for the clearly cracked gland and the threads on the gland. Threads on the cylinder appear to be OK....

If I'm unable to locate a source for parts/new cylinder, will see if new gland can be made...I had an over the phone estimate of $300 to make the gland (they didn't see the part, just ball parked it)....have seen many new cylinders for that amount, or less.... I'd rather a new cylinder or new part if available.

Idea to ask some TBN advertisers is a good one... will follow up.
