3 pt linkage adjusting.

Ak84

Hi All.
I want to adjust the width of the lower lift bars on the rear of a MF 4255.
However, the stabiliser adjuster is not budging by hand or by vice grips.I presume this is how you change width.
I was wondering is there a special tool as it's a bit strange that there are no arms or handles to turn the adjuster?

Is it threaded? If so, the threading is seized. You might free it up with oil, or it might need to be heated...

Can u stick up a photo please? More than likely seized. Have you a stenson wrench? If you haven't room, take it off the tractor
Do you have hooks on end of your lift arms?

Thanks Guys.
Won't be back there till weekend so no pics.
They are not hooks on the lift arm but I suppose balls with a hole in them.
Yeah I might have to remove it completely and try the oil or heat it up.
Thanks again.

The thread just pulled apart on one side of tractor. Never used here in ten years. 1500kg of fert swinging just took here over the edge!

On previous tractor I had to heat them the one time I needed them. Hard to keep them right if they don't get used.

Just grease them

No grease nipples on these. Should have spun them off every couple of months and copper greased them. When I'm buying the new one I'll look for with grease nipples.

Take a photo, any 4255 I have seen to date has pin and slider. Much better job IMO.

Iv heard lads using copper grease, is it supposed to be good,
What's the difference with ordinary grease

Grease will eventually go but with copper grease it will leave a copper film. Copper doesn't rust so bits shouldn't fuse together.

I've a small drum here of diesel I drained from an old tank. Great to soaked seized parts in to free them. Copper grease by the way is more suited to parts that don't unscrew that much, like nuts etc.

Dont grease them, take them off wire brush and apply silicone dry lube. Keeps off water mostly and doesn't attract the grime like grease.

Should anyone be thinking copper grease is the answer for bearings, it is not. It’s suited for mating/threaded parts that don’t move very often, and is very useful for that. EP2 grease is what is normally used for bearings.
However, check with manufacturers instructions. They don’t specify a type of grease for the crack. I had failures in an industrial environment where, too much, too little, too low a grade, too high a grade was used. High tolerance applications need the right type of grease at the correct intervals.
It isn’t always “greasy” grease that is required.

i was looking at side links stablisers on a massey today and they only had thread on one side and the side seemed to just slide in and out.should there be a spring on that side internally
