Sundstrand hydro / Auto 16

  90-1140 Sundstrand  ,  I finally got around to opening up the pump today ,here are some pictures , So take a look and tell me if it can be saved .

The 9 pistons & slippers are junk.  Take the charge pump housing off and look at the Gerotor set...THAT's what pumps the oil and provides pressure.  The swash plate look bad too.  The base of the cylinder block looks saveable...but are the cylinder bores damaged...?  If so, it too is junk.  From what I see, you will also find similar damage inside the Hyd MOTOR...it is attached to the gearbox and shares the common oil.  Pull it off and have a look-C.

Yep swash plate is wavy like the sea , cylinder bores look and feel good to my surprise I do not have any experience with this set up but as far as the piston movement in the bore and looks they seem ok is there a bore spec ?  , I do have the hydro motor on the bench already , when I opened the pump up and found this catastrophic failure I stopped disassembly ,I did not think it was worth going beyond this point ,  is this going to be cost effective , because as you say odds are similar damage with in the hydro motor.

Your location is not too far from the BiG Show, might find a doner there?

There's usually a good selection there.

well its not around the corner , but most likely I will be attending , it would be nice to get conformation on a available pump and motor , or complete transaxle ,I did put up a wanted add here some weeks back in hopes to work out a pre BIG Show order.

A we3ek or so ago, a guy was lookin' for a replacement motor shaft and some of the internals....his was FUBAR.  Forget on what forum though...FB Instagram Red Sq... don't recall.  MAYBE he could get parts from you.

Well I would have to see what direction I am going with this tractor first , and if that direction left me with this unit just sitting , then yes pay for the shipping and I would send him what he needs . Since I know you are well versed with the Sundstrand , I have a question, I do have a good 2046 pump and motor , would there be anyway to use parts from the 2046 and or adapt it to the 90-1140 transaxle . or  would finding a 2046 transaxle  for the 2046 pump and motor I have  be ok  behind the Kohler K341 .
