Rusted lift arm ball

[Spiros]

I soaked my lift arm fisheyes in phosphoric acid overnight. Rust away or something like that. Coca cola works well too. It has phosphoric acid in it. Next day
rinse and lubricate.

A friend of mine got an old CJ-5 with a frozen four under the hood - couldn't budge it with a 6' cheeter. He made a concoction of 50/50 auto transmission fluid and acetone and let it soak for a few days - and he was able to break it loose without the cheater and got it running nicely. I'm going to make up a batch just to have, next best thing to Kroil, he says, and nowhere near the price.

I religiously oil mine twice a year when I do the 'seasonal changeovers'.
Those, and all the rest of the linkage components
I do believe it has paid off as my CUT is an'80's and everything is nice and free.*

(My cut has no choice but to sleep in the elements)

*LOL, bit too free as I lost a T-buckle and that was not 'free'.

I think that's great advice. A light coat of grease goes a long way - stitch in time sort of thing, eh?

Its an gooey, slick PITA but every spring I grease the balls. I rotate them so they are a "no hole showing" situation and then slowly rotate and grease.

I use Permatex anti-sieze on the lift arms and top link threads.

I had an old Nuffield 465 from 1968. It came with Cat 1 and Cat 2 balls which you could interchange.

The method of retaining the balls in the lift arms sockets was poor and I spent lots of time re-tracing my path to find a missing ball.

At TSC they were selling new lift arm ends with the balls permanently installed.

I bought two and had a real welder put them on the lift arms. $25 each in Canada today.

It helped in another way as the lift arms on the Nuffield were too short for some pto implements resulting in high pto joint angles.
These weld on ends added about 5" to the length of each lift arm.
Of course they ends could have been welded on to produce the same arm length.

It was not an expensive project. My experience with other tractors has been if the balls start to get seriously rusted, they rust the second time much more readily.

You'll have to try a 50/50 mix of ATF, and Acetone, next time you come across something like this. Beats both PB, and Kroil, and I thought Kroil was the best, but, not so. Just mix it in a dish detergent bottle with a snap lid, to keep the Acetone from evaporating. It will also remove paint, so keep that in mind. Buy a quart of each to try it. I now buy both by the gallon, and lasts for years.

I discovered that the ball on the lift arm on one side of my JD 2025R was still cemented in place by the paint applied at the factory. Guess I need to soak it in paint thinner.

When putting the bush hog on, I found the right side arm would not move right or left to ease the moving of the arm to different holes to try for when lifting the bush hog.

Once bought a rotary plow from the old Gravely dealer in town. The wheel on it was totally rusted in place. I kept applying WD40 and PB blaster and heating and banging on it. Finally came loose after a few days.

That's what my buddy said. Nice to hear it is better than Kroil. I have a bottle made up just waiting for a place to use it - where is serious corrosion when you want it.

WD40 works fine as a cleaner for me, and leaves a light film on tools, but I would not count on any rust protection from it. I use Fluid film on the balls and most other areas of the tractor for rust protection and mild lubrication. It creeps over time, so it will crawl up into the ball socket if you spray close to the seam.
