Super Dexta Draft control

nedwobj · Post by **nedwobj** » Thu Sep 23, 2010 1:56 pm

Hi all,
I am new to this forum and this is my first post..
The draft lever on my 64 Super Dexta is stuck in the up/off position and will not engage, does anybody have any ideas what can cause this to happen. The Hydraulics work fine to lift the slasher from the quadrant lever but no draft..
Cheers John.

Welcome aboard John. I'm sorry I cannot help but I'm sure someone will come to your assistance soon. Maybe something minor, well lets hope so.

Nice looking Super you have there, please can you put up a few pictures.

Your internal linkage is seized. You will need to take the top off and see what is wrong. Then you can free it up. Not a bad job, you will need to check the position control pin as well and reset the linkage adjustments but it is all pretty straight forward.

Thanks so much for your replies and kind remarks.
Since I posted the draft lever problem the situation has changed somewhat... The main quadrant lever has become very loose and simply drops down to the bottom when released. When raised to the full lift position nothing happens until a slight pressure is applied to the Draft lever, then the arms lift as they should and hold OK. The draft is still stuck in the up position but responds enough to work. Arms will lower as normal from the main lever..
The hydraulics appear to be working good, so your thoughts on internal linkage problems seems very plausible. I do have some mechanical knowledge but not sure if I should tackle this one.
Cheers John.

Sorry Mervyn, couldn't work out how to post photos. " but I will ".

You have the normal Dexta problems of worn Position Control pin and Seized linkage. All your symptoms point to that. Check the Wiki for settings and check the site history for others who have had the same. Must be many post on here.

We can talk you through any problems you may find.

Thankyou Brian for your help.. I have read the manual relating to this repair and it looks like a simple procedure.
Might have a go at this one myself, not sure if parts are still available for these old girls. ' replacement position control pin'.
Regards
John.

Position control pin can be replaced by using the shank of a 5/16" drill. Just cut a length off with a grinder.

Thankyou to all who have posted help here.
I have been reading the online manual for the Hydraulics section
and have not been able to find any part in the diaghram that is called a position control pin.. The only part that I can see that
looks as though it could be cut from the shank of a 5/16' drill appears to be the small axle that the position control arm rotates on. Am I on the right track here or completly wrong..

Regards to all
John..

It was never a Ford part, it goes in the Position Control arm and runs on the cam on the big lump that the con rod fits in, that is on the cross shaft.

You are in the right area but it is clearer when the lift is off.

Thankyou Brian, I now believe I have the correct part identified.

Page 22 / Fig 32, referred to as the 'STOP PIN' ,fitted to the centre of the position control arm and appears to run on a cam.

Hi Mervyn, This old girl has been pretty much reco'd from ground up with any worn parts replaced. Unfortunatley at the time the hydraulics showed no signs of any problems .When this photo was taken it was all working perfectly.Something has let go inside. I believe Brian is on the mark with the position control pin worn out. I haven't pulled the cover off yet to have a look. I took Brians advise and checked out some of the older posts. "It is such a common problem with Dextas". One member actually had a piece of wood jammed behind the Draft lever to hold it in a certain position to obtain lift control. His problem was also a worn pin. I can't thank you guys enough, just glad I found this website. I will place a few more pics later on. Cheers John.
