oneshort 4 #1 Posted August 31, 2016 Hello all; I have a 1966 model 876 automatic drive with the sundstrand 3100077 transmission. while repairing it i lost one of the " round wire" snap rings that holds the gear motor gears in place.I can find numerous diagrams of the piston pump but none of the hydraulic drive motor. I have been unable to find a part # for the snap ring. I'm hung -up! Thanks for any help! oneshort Share this post Link to post Share on other sites
