Howard2x4x4 0 #1 Posted June 1, 2014 My 518 H (1980 +/-) stopped moving on me this week. I (along with a buddy much more adept than I am) noticed big time wobble at the cooling fan. Pulled the right rear tire & rim & fan & pulley. The pump shaft wobbles like crazy. Appears to be a sealed bearing around the shaft. What next? Are parts available? Help! Thanks!

dwcphoto 7 #4 Posted June 6, 2014 The hydro on my 518-H went soft a couple years ago. I was able to get some more life out of it by using 90 weight gear oil. I found a 520-H rear for sale and with the help of the guys here and a friend I mounted that on the tractor and it's good as new. There was a lot of comment about the hydo on the 518. Here's the link to one of the threads that was very helpful to me. Disregard my talk about the Sunstrand as it turned out irrelivant. best of luck, dwc Share this post Link to post Share on other sites
