NAA 3 point hitch no adjustment

5

53-Ford NAA

New User
Hello ALL,
I have a Ford 53 NAA which I bought about a year ago. This is the first tractor I have even owned so please bear with the newbie.

I have recently tried to use the 3-point hitch. It will go up and down but if you move the adjustment lever up a 1/2" it will go all the way up or move it down a 1/2", it will go all the way down. It doesn't matter which mode its in (draft or position).

PTO works fine.

Any ideas where to start looking to solve this issue?

Thanks in advance for any help!!!

Was just reading about that over the weekend. That cam follower pin is special diameter, don't use a
5/16" pin it will crack the housing it drives in. A suggestion was to turn the pin over if it isn't
worn too bad. Yesterdays parts, it's in the clutch section.
 
hello Everyone,
I am getting back to this original post. I have not needed the 3 point hitch so i let it go until today.
I opened up the lift housing and inspected the cam follower pin. I see no sighs of wear and the pin mic's out at .304 and from what i read it should be .309. I am assuming the pin is fine.
I still have the original issue which it will lift and lower only in a narrow band about 1/2" movement on the selector level. it does not matter what position i am in Draft or Position it does the same thing.
The lift will drift down with a heavy load on it. from all the way up to all down takes about 4 mins. i know i need to address this but i don't think that is my issue.
It looks like this has been taken apart before and I am assuming the cam follower pin replaced but i am wondering if was put back together correctly.
the internal springs in some positions have no tension on them.
I will try to post pic.
any other ideas on what i should be looking for?

Thanks

that is part of why i think it was put together wrong.
the manuals states to

"adj gap between end plate and control valve to .185 by adjusting the turn buckle"

there is not enough turn buckle to provide this gap. it closes to 0 about 1/2 way thru the selector lever travel.

aybe you just left that portion out, but there are "conditions" at the time the gap setting is made, such as position of lift arms, position of draft/position control, position of touch control lever.
 
I had the arm 1/2" to center from the top of the housing, in the draft position and control lever in the top most position.

Is this all correct?

elieve that sounds correct, but the touch control may be slightly below full up, by maybe half inch........see if that will get the 0.185?
 

not even close moving up the control lever when i get 1/2 way up it closes to 0 gap with the turnbuckle screwed all the way in
 
How is rust/corrosion in the mechanism? When you move the touch control lever thru its full travel does the end of the arm attached to turn buckle move uniformly thru that full lever travel of perhaps it moves the control valve/turn buckle over full range with only an inch or so of touch control lever?
 
it move fine. needs a friction disc but it travels fine.
I really need to see a completed pic of a correct assembly to insure everything is correct.
In the position mode I am assuming that the position control cam should push on the valve assembly but this one is not. it bare touches it and never moves when i move the lift arms
thanks

White represents(marks) the control arm. This arm has 3 points, each of which can be a pivot point or an input point. When in position control and you move the TC lever, the input is via the eccentric and the pivot is the pad on the ctrl arm where the position ctrl spring/rod assy contacts the pad. At this time the draft input is not active because that rod/spring/bushing is floating freely inside the swivel. When TC lever is stationary and the lift arms fall, then the cam/cam follower will move the position control spring/rod assy toward the ctrl arm pad and this then is the input point and the eccentric is the pivot point.
When the Posn/Draft lever is moved to DRAFT, that action moves the cam-like device at rear of posn ctrl spring rod assy such as to compress the position control spring & pull the rod away from the control arm pad, thus by default leaving the draft spring/rod/swivel as the input/pivot point on the ctrl arm, instead of the position ctrl pad. Now either this swivel or the eccentric act as input/pivot or pivot/input. Bushing no longer floating in swivel, but in contact with swivel. Hope helpful.
 
It all looks the same as what i have.
I am now thinking the draft control spring is my issue. thats is the pivot point and i think it needs to be moved forward to pivot to make the needed clearance.
I will work on that tomorrow

Thanks
for your help and pics

don't follow you, since moving that forward will push the control valve spool further into the ram/valve casting assy?
