Ok, Put the new parts on from "john smith" (2 triangular plates) for the draft control spring. Follow adjustment procedure in I&T manual. Lift stays in the up position, won't go down. So I tried one turn at a time tightening and checking. Finally got to where it will raise and lower. But, its a little jumpy going up, and with a load (wood) on it, you have to keep it all the way up or it drops. I don't want to keep tightening and cause more trouble. This lift worked perfectly before changing parts.

What to do next

You make no mention of the Quadrant adjustment. If you have not gone thru that procedure, I suggest you put draft spring back to not tight/but no slack state & adjust the quadrant as per the FO-4.
 
Real confused. I put the spring back to specs. Attached a grader blade. Lifted it up. Started pushing the lever to lower. It went about 7" before starting to lower :shock: :? It's about 1/2" below the stop when it starts dropping. If I pull back to the stop it holds. The lift never used to leak down (all hydraulics rebuilt just over a year ago after buying it) but now it does. It creaks as it drops. Any suggestions? Thanx

OK...I'm gonna try to help you understand what adj. you have to make.
First off.....you only did HALF of the adjusting that JMOR said for you to do!!!!!
JMOR said:...You make no mention of the Quadrant adjustment. If you have not gone thru that procedure, I suggest you put draft spring back to not tight/but no slack state & adjust the quadrant as per the FO-4.

SOOOO, now go back to pg. 90 in your I&T FO-4 manual, and read para. 149 and 150. This will tell you how to adjust the Quadrant, and the control spring.
Do exactly what it says there and try it numerous times, with the blade on, then come back and let us know how it works.

Not trying to be a smart a$$, just trying to help you get going.

My FO-4 manual only has 39 pages. Quadrant adjustments are para. 99, control spring para. 100
It says the lever should move 2 1/2 - 2 3/4 to start lowering. Mine starts lowering after 7+ inches.

I adjusted the quadrant fully to the front and now it starts lowering at 5 1/2"

You keep talking about the stop. If what you are taking about is the flat bar with a wing nut to tighten it, that stop is not used in the adjustment of the quadrant. Loosen the wing nut and move that stop all the way to the bottom or top of the quadrant slide, tighten it down, and forget it is there until you get the adj. done.
Then start at the quadrant adj. for the 9N/2N, and follow those instructions.
Sorry about the pg. thing in the FO-4, I just assume everyone Buys/has the new 152 pg. manual. That one has more info.,and pictures of everything.
Try the above, and let us know what it does. May take three or four tries to get it right.!!!!!

Ok, here we go. I just bought this manual last fall at TSC?

I was confused on the motion of the quadrant movement. Thought loosening it would allow it to move in a clock motion. Did not realize they were slotted. My bad (all new to me). So I loosened the 4 bolts and slid the quadrant back and that was the wrong direction. Slid it all the way forward and now instead of 7 1/2" travel, it only 5 1/2" travel. Still way out of spec. but better. With the lift up, the spring is adjusted fine.
This is about where its always been since having the tractor.

Only difference now is that it still creaks and won't hold the load when sitting awhile. We used to be able to leave the blade in the air for at least 4-5 days before it came down.

As far as the "stop" I was only using that as a reference so you know how far my lever is?
 
When the lever moves another 1/2" down, the lift starts dropping.

OH NO!!!! YOU must be a mind reader.....I was just set to ask for a picture if you had it......and there it is!!!!!!
OK...now it sounds like all you should have to do is set the friction pad tighter, to keep it from going down as fast as you say.
You need to remove the cotter pin, from the castelated nut at the end of the control arm, then tighten up that nut till you have about 4 1/2 lbs to 5 lbs of friction on the control arm. Then tighten up that nut till you can just get the cotter pin back in.
NOW test it and come back and let me know if it works good, or is where you want it.
I think, that should keep it where it is supposed to be, unless you have other prob.'s with leaks in the hydrol. sys.
The reason that it goes down quick, is prob. not enough friction to hold it.

I waited for about 1 hr., but did not get a reply from you, sooo, I guess it worked?????
Only have one more thing to add. Now that the friction pad is tightened, you may have to re-adjust the quadrant, for position. Just have to play with it to get it right where you want it.

Hope it worked.?????

Sorry about that. My son has the tractor out right now and company showed up. I will try it as soon as I can. I will let you know either way what I find. Thanx for the help.
 
Ok, I was only able to move the castle nut 1 notch. Worked it a few times and was able to adjust the quadrant just a tiny bit more. Now it moves about 4 1/2" to start dropping. After shutting it off, I did not hear the creaking like she was dropping. I've got a bucket next to it to watch for dropping. I think it will be pretty good. At least now I know another repair procedure. I greatly appreciate all the help. I will post back if something changes.

Glad it is working for you, and you are welcome to the help.

Been watching for an hour now and it hasn't dropped. Earlier it would drop a 2-3 inches an hour. Thanx again.
