reverse flow hyd pump, my mistake or not.

[yavapai]

I recently purchased a YM2000d with a broken hyd pump. I went to a well known company and asked for a used pump off of a "YM2000d". what I recieved looked like a great, working pump. upon install, I blew shaft seal after shaft seal. after banging my head against a wall for a week I took the tractor to a local HYD expert. he did the expected inspection, and replacement of some older lines, and after he blew three shaft seals, it was realized that the pump had a flow arrow that was oppisite of the system, and the previous pump. The mechanic repaired the old pump installed a new seal and the tractor functions perfectly. has about 5 hours on it at this point.

if one was to find any "accepted" schematic for a 2000d hydraulic system it shows a conflicting flow from the pump I recieved, but is a perfect match to the tractor I own, and the pump that was taken off originally.

anyone know why there would be a pump that would fit on a 2000d that would be different from any standard 2000d tractor? did I not make myself clear enough by asking for a "used pump for a YM2000d"? I paid the HYD guy 350.00 dollars (which is fine) but now Im out 200.00 dollars for the pump that wont even fit on a standard YM2000d.

Do I approach the company, or did I make a mistake?

thanks

It would be very help full If you posted a picture of your pump and hydraulic lines. Hoye would not do you wrong purposely And will probably even give you a refund. But it sounds like maybe your tractor was re plumed. I'd love to see that picture.

go to their website, and thier hydraulic schematic is identical to mine for that tractor (YM2000d). My tractor is factory, Suction (supply) from the top, pressureized side on the bottom.
