With some painfully learned lessons, I want to first note that the I&T Manual from Tractor Supply has provided me with more info than the OEM service manual ever could. I wouldn't have had to purchase a new (used) control lever rod ($55 off ebay) had I had this manual. The overall issue is that the hydraulics would not completely lift.
So far:
-Upon visual inspection the linkage, and everything else for that matter, is coated with old hydraulic fluid that has since turned to grease.
-Not sure how loose all the linkage is supposed to be, but it's pretty sloppy.
-Removal of the cylinder was easy. Have yet to remove piston but a new one with seals has been ordered from this site.
-The friction plate was seized to the woodruff key, and it wasn't until after I had messed up the above noted control lever rod with a grinder did I finally split it with a chisel. (This was noted in the I&T Manual, so getting it a day late cost me $55)
-"Cam follower pin" on the Touch control linkage looks perfect, however the same pin on the draft control linkage is very FUBAR. It appears to have been rubbing against the main spring of the touch control linkage. Correct me if I'm wrong, but I attribute this to the amount of slop and wear at the connection point of the draft control plunger and the "fork" at the very rear of the lift cover. Also this pin looks to be work half through where I'm assuming it rides the cam on the lift shaft. (Ordered Zane Sherman's fix for this)
-One lift arm came off, but the shaft doesn't want to come out of the lift cover.
-The flat head plug that retains the spring and ball for the draft control lever had to be drilled and removed with an easy out, I found a seller on ebay that makes them a little better, but they're pricey ($16 shipped for 2, at least ill have a spare)
Now for the valves:
-Check Valve spring was found broken.
-I can see that the backpressure valve spring is "cocked" or broken as well but have not yet removed the checkvalve seat, and I'm pretty scared of doing it because I can't find the replacement part.
And that's where I'm at with this. If anyone here knows where I can find the replacement valves and seats I would grateful. I know form reading that they are color coded, but theres no color markings left on the lift cover assembly.
Feel free to post any questions or comments.
