I'm the lucky? owner of an early 175 that has the flat bottom (506322M92)auxiliary hydraulic pump. The pump should be replaced but isn't available. What are my options? I have a front mounted pump on the tractor that I can use for the auxiliary hydraulics but I need this pump to run the multipower.
Thanks

Yes, but how do I mount it? Those pumps mount with the newer style mounting plates, mine mounts with a mounting pad on the bottom that is part of the pump body. What other parts do I need to make it work?
Thanks.
 
This is interesting, from the AGCO online parts book.

The service kit 517614M95 is a adaptor setup for the newer style pump. I could only find one service kit 517614M95 at TractorHouse.
 
I wonder if a salvage yard would have a complete newer style unit that would bolt in to my tractor? Of course I still might need to replace the Aux pump if it's bad.

There is bound to be a newer 3 point lift pump with a axillary pump that will bolt in place of the old style. Dieseltech here on the MF forum may know what pumps can be used to replace the old style like you have.
