Dieselcowboy 210 #26 Posted April 23, 2014 (edited) I won't have enough time to gauge anything today but I did look at it and started it , when I slightly pull the lever it squeals. I don't think my old 520 did that. also cyl doors have free movement with no implement attached.I did just got out to the farm where my old 520 resides. it doesn't squeal near like the 96. it also lifts a 60 inch deck at an idle. I think I'll shoot for the spool valve first. think I might have one located. Edited April 23, 2014 by Dieselcowboy Share this post Link to post Share on other sites
Dieselcowboy 210 #27 Posted April 25, 2014 Thought I'd finish up this thread. Found the problem. I got bold and took the acorn nut off the back side of the spool valve. There is a allen set screw inside. I tightened that up a turn and up and down it went. So these valves must be adjustable pressure. The loud squealing is also gone. Thanks to all for the help.
