Ford 3000 diff lock pedal linkage

JerryLook · Jun 10, 2021

The diff lock pedal on my 3000 is locked up, and I broke the linkage between the pedal and arm. Is there are source for new ones (or something that will work the same), or should I source a used one? I can get a used one for about 40$.

Also Ive read that I can break the diff lock free by putting penetrating oil on it a few times, and working the arm. Will that work or is there something inside the diff I need to mess with? Im going to have the hyd cover off soon, and thought maybe I could get to it from there.

The diff lock worked on the tractor when I got it, but I some point became frozen because of lack of use.

Not clear where it is froze up.
Is it froze up at the top - inside the rear end housing or is it froze up at the bottom - externally where the pedal pivots on the axle?
If internally I don't know what would cause it to do that. It is a pretty simple mechanism inside. Perhaps the shaft #20 is froze up from rust, etc. If that is the case you might free it up by drilling a small hole in the cap/plug #23 and squirting penetrating oil in there. Worst case you might need to pull the axle housing (trumpet) to free it up. I doubt you can do anything to it from the top cover.
If it is the pedal pivot on the bottom of the axle that would be easy to remove, free up and grease.
I am going up to my property tomorrow. I plan to remove one of the trumpets on a scrap 3000 rear end to use as a pedestal for another bench grinder I bought. Can't remember if it has diff lock on it tho. If it does I could remove the right trumpet and sell you the linkage. But even in a USPS flat rate box shipping would push your cost to most of $40.
My email is open in Classic View.
P.S.
Those trumpets make great pedestals for stuff

Sorry I forgot to specify. Its the arm that goes into the rear end thats frozen. The pedal moves freely.

One day I stepped down onto the diff lock and bam, the linkage broke. Its been something Ive been meaning to mess with for years. I usually dont have to use the diff lock, but when I need it it would be nice.

Thats a cool idea using the trumpets for stands. I imagine they weigh quite a bit, and offer a stable platform for stand mounted tools. Plus a good conversation starter. Lol.

Dang it Jerry, I thought I was the only one with that idea for repurposing old trumpets....
