Krice58 90 #1 Posted October 31 (edited) I’ve posted about this tractor before, 1975 C160. I think I need to rebuild the hydro and I will at some point. In the meantime, I found a ‘77 C160 with no engine and a good hydro. I figured the easiest way to get it going would just be to swap the whole rear end, hydro and all from the 77 to the 75. From what I’ve read the hydros are the same number, both are hydraulic lift. I would assume ‘77 to ‘75 would be plug and play with no modifications. Of course it would be easier to just take the engine from the ‘75 to and put it in the ‘77 but the ‘75 is my grandfathers and it has a lot of sentimental value to me and it wouldn’t feel like his anymore if I took the engine and put it in an entirely different tractor. I understand I’d be essentially taking half of another tractor anyways, but there’s just something about having the same steering wheel, same footrests, seats and hood that my grandfather used that’s important to me as dumb as that sounds. Any help would be appreciated. ‘75 is a 1-0481 and ‘77 is a 71-16KS02. Edited October 31 by Krice58 Typo 1 2 Share this post Link to post Share on other sites
daveoman1966 3,877 #2 Posted October 31 I have the same C-160 auto. The Sundstrand model 90-1140 is NOT difficult to rebuild---I've done several of them. If you know your way around a screw-driver and a wrench, you can do it too. Here is a FREE 'refurb' .pdf manual I prepared as a guide. You can still get gasket and O-rings from on-line sources.

This is just to get me going. Where are you able to find parts for the Sundstrand? I can only find bits and pieces on the bay. Share this post Link to post Share on other sites
ineedanother 1,729 #4 Posted October 31 I would just swap the pump and motor as one unit. It's still a bit of work and one gasket while you keep the machine sitting on four wheels. 1 Share this post Link to post Share on other sites
953 nut 62,218 #5 Posted October 31 Pump swap would be the quickest and should give you the operating Wheel Horse in an afternoon. Load them both on the trailer and head to the carwash first, cleanliness is very important. 2 Share this post Link to post Share on other sites
Krice58 90 #6 Posted November 1 Transaxle was already out of the 75 so I just swapped in the ‘77. 4 bolts, a bottle jack and some furniture dollys. I powered washed it to get the loose dirt off, now to deep clean it before change fluids and filter. 1 Share this post Link to post Share on other sites
