Dewsford 0 #1 Posted March 9, 2020 I was using my d200 and it started vibrating like crazy. Looks like I broke the engine to hydro coupler. does anyone know that part number for it so I can buy a new one? Share this post Link to post Share on other sites
JoeM 7,871 #2 Posted March 9, 2020 This is the parts tree page for a 1976 D200. Looks like the rubber insert is available but the spline piece that mounts to the pump is no longer available. I might have the rubber insert but not the spline piece. Usually the splines on the pump go bad and wallow out the insert piece. Some have drilled the insert piece and pump shaft and pined these on to prolong the life. https://www.partstree.com/models/61-20ks02-d-200-toro-lawn-tractor-1976/4-050-hydrostatic-transmission-2/ 1 Share this post Link to post Share on other sites
Achto 27,502 #3 Posted March 9, 2020 If you end up drilling the insert & shaft I suggest using a heavy duty roll pin. A roll pin will keep constant pressure in the hole so that it has less chance to wallow out. 4 Share this post Link to post Share on other sites

Are you going to sell him one, or are you just rubbing it in like in the other thread??? Edited March 10, 2020 by WildmanC120 1 Share this post Link to post Share on other sites
