pump replacement?

[TractorTech]

thought it was a bit spendy for a used pump which might be 90% wore out

You were asking for a replacement shaft for your pump and that is not how it's done. This pump may be worn out, meaning the housing is worn out, but the gearset may work in your pump. I would think that is not the case and you could ask the seller or counteroffer at half the price.

i can fabricate a new mount no problem. not sure how i find a matching pump tho. just using the number off the casing? didnt have much luck on google?

The numbers on the case didn't do anything for me, despite much effort. I don't know why, but it seems that the pumps have nice numbers stamped in that don't correspond to anything.

I started at the tractor manufacturer parts book, and got their part number. When I googled that, some vendors had the pump advertised, and they also had the Bosch number.
Rather an archaic way to find a part! it worked though.

i too looked at the parts manual for the case 1816 that this is out of. there are two pumps specified neither match the number on my pump... they were very similar though. so your saying you found some pumps? i appreciate your effort. where do i go from here?

I just put the rexroth number into google, and an ebay ad popped up.
It was unused old stock, and I got it for $100 incl. shipping.

There are various flanges, shafts (straight, cone, spline), centering ring size, and most importantly rotation direction.

My tractor had 2 different pump sizes, the US version had 19cc, the EU version (mine) just 14cc. I found one with 22cc that bolted on.
