AHS 1,440 #1 Posted October 19 C120/sundstrand w/hydro lift. It runs and moves just fine, the issue is with the lift. In the lift cylinder. once the cylinder is all the way extended, there is an extensive leak around the stem to the cylinder. Alright, so i went onto Wheelhorsepartsandmore and looked up the seal kit. Now the site said the seal kit would only work from late 70s thru 520. The C120 is an early 70s. My cylinder looks the same as what they show… 1 Share this post Link to post Share on other sites

The Charger and C Series tractors I've had from 1970 to 1978/9 and the 1984 GT1800 all had a welded cylinder. They're not meant to be serviceable by normal mortals. @wheelhorseman Lowell does cut & rebuild them. Share this post Link to post Share on other sites
Blasterdad 2,692 #5 Posted October 20 From the description....Cylinder has a snap ring, more than likely this is the seal kit for the cylinder. That is the easiest way to tell... 1 Share this post Link to post Share on other sites

That is exactly what I have and here is how I stopped the leaking cylinder: This was an easy fix and I did not have to cut/reweld the cylinder. It STILL does not leak or drip.
