elixir20 1 #1 Posted March 31, 2011 Sorry if this is a stupid question, but I cannot find the model # of the sundstrand pump on my 1979 C-161 twin auto. Can anyone tell me if the sundstrand pumps on the same era C- series are all the same and would be a direct bolt up to mine? thanks guys! Share this post Link to post Share on other sites
oldredrider 2,549 #2 Posted April 1, 2011 Not a stupid question at all. Your tractor should have the 90-1173 Sundstrand transmission...the same one used in C-series 1978-1980 models. Also used in '78-'80 D-160's and D-180's. Hope this helps. Share this post Link to post Share on other sites

Kevin Bowley 130 #5 Posted May 8, 2011 The D-Series tractors used a much larger dual stage Sunstrand 930 mounted directly to the engine. Here is a Sunstrand pump from a c-120 that will bolt right up Sunstrand pump for c-120 on eBay Share this post Link to post Share on other sites
