I'm looking for the Vickers part numbers for the cartridge in the no46 control of a D7-17A. The pump was worn out when I got it. I put new seals and bearings in it and had a machine shop resurface the brass end plates, I also had them try to clean up the ridges worn in the pump ring, but they weren't able to do much. I reassembled the pump and it was much quieter and faster, but as I used it and the fluid began to heat up it gets very weak and noisy. Cat can't get parts for them anymore and no one at any hydraulic shops could cross the cat numbers to anything useful, so I figured Vickers would surely have their own part number for the cartridge, but I can't find it. Where else can I look.     Thanks 

What's the s/n of the Hydraulic Control??? Or the Cat number for the pump.
I can get the cross over number to Vickers but I doubt it will do much good as far as availability.

sperry vickers is now part of eaton. so there is somewhere to start.

We had a lot of rain last week, had to dry up to get out to the machine. The hydraulic control unit number is 48C7347

Here's some Vickers numbers....
48C7347=4H3689 pump group = 4H2087 cartridge
4H2087 cartridge = 40085-X
6F5907 bushing = 20567X = 171400
6F5908 rotor = no interchange number listed
4H4391-Kit = 12 vanes = 912130
4H3688 Ring Assy. = 40086X
6F5906 Bushing = 20566X = 171398

Thanks for the info. I have not had any luck finding the cat numbered parts, but figured there maybe some NOS Vickers parts floating around somewhere.
