Macgyver 90 #1 Posted November 12, 2016 I'm looking at buying a C160. I understand that it has a Sundstrand axel Is there a reason why I can't change that to an Eaton 1100? I just happen to have one in the shop. 1 Share this post Link to post Share on other sites
Sarge 3,463 #2 Posted November 12, 2016 It really shouldn't need to be swapped - the C-160 used the later model Sundstrand and every one I've tried has been strong as an ox...but I'm sure it could be done with the right parts to swap it . Sarge 2 Share this post Link to post Share on other sites
illinilefttackle 399 #3 Posted November 12, 2016 Sarge is right- those Sundstrands are designed to handle as much as 20hp more than Eaton 1100- Good Luck!- Al 1 Share this post Link to post Share on other sites
BOB ELLISON 2,981 #4 Posted November 14, 2016 I have 2 C160's with the sundstrand and both work very well. One has 10/30 Moble 1 and the other has transmission fluid in it .The PO eather changed it to transmission fluid or it came that way new. would not change them with a Eaton 1100 unless I had no choice. One is a 1974 and the other is a 1977. 1 Share this post Link to post Share on other sites

Could you expound upon that? The Sundstrands on the 160s were beefier? I have one so that would be nice to know. 2 Share this post Link to post Share on other sites
pfrederi 17,902 #6 Posted November 15, 2016 Internally all the hydro gear sundstrands were the same. Different model # usually involved the year or some external variance. The internals of the piston to piston were also the same except for the addition of a band brake in later years. D series Sunstrands handled 20 HP without an issue so long as you kept fluid clean and didn't grind up the parking brake. The weak spot was the splined coupler /input shaft between the engine and the pump, nothing to do with internals. 2 Share this post Link to post Share on other sites

Dennis- when I was reading up on the Sundstrand I had in a 16 auto that I was restoring-I came across an article that claimed they designed to handle up to 45hp. I will see if I can find it again-it didn't surprise me because if you compare the transmissions- the sundstrand even looks beefier-hose & fitting sizes, etc. Thanks- Al 3 Share this post Link to post Share on other sites
smoreau 658 #8 Posted November 15, 2016 Eaton in my opinion is a stronger axle hands down. Larger axles, stronger lift pressures, much stronger diff, and easier neutral adjustments. I have both and have been into both foe one reason or other. As for changing one for another, the thought has crossed my mind and you would need a doner tractor for all the linkage parts and parking brake would be pain to get to work like it should. I do use my parking brake all the time and has saved me from more runaways then I want to talk about. 3 Share this post Link to post Share on other sites
