Replacing C-121 Hydro.

[MalMac 1,331]

I have got a C-121. I have reason to believe that the hydro is junk. Now I have got 2 part tractors that have good trannys in them. One is a C-195 and the other is a C-175. Now I know the hydros are different, with the part tractors having Eatons in them. The question is- can I just swap the whole rear tranny pump and all? Will a eaton pump and tranny bolt right up in the C-121? At first appearence they look like they would. The hydros are a different world to me. I am used to the 3 speeds and 8 speeds.

I beleive you can swap the 175 but you need to change over all the motion control parts along with the fender pan mounts. The C195 trans has different bolt patterns and will not swap out.

edit; I am refering to the complete trans assembly. The pump will not your 121 is a Sunstrand hydro and the 175/195 is a eaton
