Hydraulic Pump foran 1800A

I just got back from the AGCO dealer (old Oliver dealer) with some bad news. The hydraulic pump that I need to replace in my 1800A checkerboard has been discontinued.

The part number he found in his book is 104404AS. Ebay lists several hydraulic pumps for an 1800A but they have a disclaimer that "If old pump has bolt-on cast iron suction discharge fitting w/ relief valve, this pump will not fit applications". My dealer says the 1800A has this.

Does anyone have any ideas on how or where I can get the correct hydraulic pump for my 1800A?

Thank you.
 
Are rebuild kits still avaliable? If the guts are bad, you best be might be to get a used one.
 
My dealer said that when the seals go bad on these things that's usually an indication of bigger issues with the pump. He didn't think you could just replace the seals or rebuild the pump.

I was actually hoping someone knew of an old dealer somewhere in the country who might have one on the shelf for awhile.

Buying a used one might leave me with a pump as bad or worse than the one I already have since these things are 50+ years old.....LOL
 
I would not get a used pump either. However I would think about a housing off of an 1800 C series or a 50 series housing. Many improvements whenyou go to that. Questions?
 
Why do you think the pump is bad? There are a couple of other items that you need to check that give the same problems as a bad pump.
 
greatly reduced 3-pt lift capability. with loader installed and a heavy load like 1500 lb hay bale, the power steering is almost non-existent. Loosing hydraulic fluid, it is emptying into the 90 wt. gear oil reservior.

If you think it could be something other than a blown seal on the hydraulic pump, I'd be interested in hearing thoughts please????
 
I was unaware that you could retrofit from an 1800C or 50 series into an 1800A.

When you say 'housing' it sounds like you are talking about more than just the pump. Can you elaborate?

Thanks
