zekepiks 8 #1 Posted April 28, 2016 I need help with the hydro unit of my 1976 c160 with hydro lift, the machined surface where the oil filter mounts is cracked and leaks oil,. quite a bit actually, I would like to find another unit that would fit and just swap them out but I don't know if all the transmissions they used on the c160's were bigger or what. I guess what I need is someone to tell me what I can use. thanks in advance Skip 1 Share this post Link to post Share on other sites

pfrederi 17,911 #3 Posted April 28, 2016 What is teh model number of your tractor. Over time the Sundstrands changed a bit...e.g. physical brakes, hydro gear vs piston to piston... Would make a difference in what you need. also look for a metal tag on the hydro it will have a Sunstrand Model ## 1 Share this post Link to post Share on other sites

pfrederi 17,911 #5 Posted April 28, 2016 Depending on the crack size you could "V"it with a dremel and carbide bit. The fill it with JB Weld and sand it smooth in the mating surface area. Would be worth a try to me before removing the hydro pump/motor, then splitting the transaxle case and swapping all the internals... 2 Share this post Link to post Share on other sites

Or maybe this approach "When my John Deere was leaking oil, I just added about a can of Stop Leak to the oil. Made it pull even better and now it will almost move." ~ Signed "Satisfied Deere Customer" 1 Share this post Link to post Share on other sites

daveoman1966 3,762 #8 Posted April 29, 2016 The RIGHT SIDE trans case is part # 103636. Here is the trans axle schematics for 71-16KS02... and other schematics as well. As noted earlier, I have this part in my shop. https://www.toro.com/en/parts/partdetails/?id=5253 Share this post Link to post Share on other sites

The print is sometimes faded or disappeared all together. Model 61-16KS02 would be a 1976 model. Model 71-16KS02 would be a 1977 model. The 7067 is the Julian build date - 67th day of 1977 = Tuesday March 08, 1977 There were often mistakes in the build date at the end of a calendar year (ie building 1977 models in 1976) but have never seem mistakes at the start of a calendar year. (ie building 1977 models in 1977) Garry 1 Share this post Link to post Share on other sites
