snowhound 105 #1 Posted September 30, 2017 I recently picked up a 1986 417-A and want to change the oil in the Eaton 1100 but couldn't a drain plug. Could someone help out a Hydro transmission newbe? 1 Share this post Link to post Share on other sites

cleat 6,387 #5 Posted October 1, 2017 You can also loosen the nut on the tube feeding the pump down low. One of my 520's has a drain plug I cannot get out short of drilling it and that worked for me. 2 Share this post Link to post Share on other sites
