4020 LOAD CONTROL SHAFT BUSHING removal

[ridgelane]

What is the easiest way to remove the load control shaft bushings on a JD 4020?

Every year without fail, one side will suddenly start leaking oil. The bushing on that side doesn't appear to have much wear but I'm at wits end as to why its always the same side and why the seal holds about a year then starts dripping constantly. I figure I might as well bite the bullet and replace the bushings and seals. Shaft is good.

Shaft is either bad or too much endplay or both.

I will add, replace shaft, bushings, seals and shim end play.

Replace it all at the same time & do the bushings in the drawbar yoke and get the aftermarket ones for in the tractor that have an o-ring in them.

Yes too much side to side end play is what kills them, Deere offers shims to take that out. As the hitch bangs back and forth it continually wears on the seals till they fail..

How often do you use draft control. If never, take those bushings to a machine shop. Have them make you some with a straight center hole,(no taper), install them and then throw those originals in the junk. Not one of Deere's better ideas. I replaced a lot of busings, seals and shafts in just four years of working at at Deere dealer. I never was able to go with my idea as of course everyone wanted it like it was originally. IH tractors are no better, as they wear out those expensive splined shafts and connections and no one ever uses draft control anyway.

That"s right Pete, load control was made for mole board plowing,,which has become a thing of the past...

Thanks for the comments. One question remains unanswered, how do I get the bushings out?
 

[Tx Jim]

Take a rod that is little smaller in diameter than the L/D shaft that is about as long,put in the bushing on one side and drive the bushing out on the other side,

Put it all in, shaft, bushings,bushings in the yoke ,(make sure the taper is in the right way ) and seals, or do it again. The shaft may look good but if its a year old replace it. Set side play as tight as it can be and still move. Just a side note if the shaft is put back in oposite of the way it came out they can break , so ive heard.
