As I near the end of my restoration, I have some bucket pins that I know are going to cause me grief.
They are circled in the picture.
I was thinking of using fire and the Harborfreight press to remove the darn pins.
The cylinder pins are easy to remove - I had them out when I rebuilt the cylinders. It's the others I fear!
I'd appreciate your experiences, advice and any magic words here.

Have you tried to remove any of them? I'd suggest removing the retaining bolts and apply a good penetrant . If the pins have been greased then the only place they'll bind is at the pin bosses. I wouldn't think they're a press fit or they wouldn't be retaining bolts. I'd try a brass bar slightly smaller than the pin diameter and a maul, hit one way then the other. Once removed install a new pin so the others don't get in a bind. Good luck

I'd remove the grey 'arms' off tractor and bucket, Place on wooden blocks,vertically,add a 50/50 mix of ATF/acetone, wait say 10-15 minutes. then try tapping out the pins, using brass rod ust smaller than the hole. if they don't budge, heat, then more 50/50, try again. PATIENCE is your best tool !!!
The press might work, but I had a 10T one break trying to get front axle Ujoint crosses out !

I always prefer a hydraulic shop press over beating something with a hammer. Your favorite penetrating-oil is certainly good practice.

You might try a ball joint press. You can get a loaner from the parts stores like Advance and Autozone. Or borrow one from a friend. put some Deep Creep on the pins, let it sit and press them out. The C-clamp on the BJP has about an 8 inch opening and with most you can use an impact wrench or pull bar to do the work.

Thanks all,
I appreciate the ideas and will give them a try.
I'll let you know what I got into and such.
I believe all of the pins are stuck in the bosses in "grey" painted portion of the bucket mechanism.

I've had to do this in the past

drill the pin as big as you can, stuff I was working on was about an inch dia pin give or take. It wasn't huge but big enough to be troublesome. Most have a 1/2" bit, I happened to have a 5/8. Make sure you start the drilling centered and straight.

One of them, I tapped the hole to fit a stud into it. Then i put a spacer that was larger than the pin, and roughly the same length of the pin, onto the outside, a bunch of thick washers, and a nut. Screwed the nut down tight and used a cheater, and it finally came loose and pulled on out.

Another one, I started drilling and then tapped-thinking it'd worth the same. Nope, just broke the stud off. Unscrewed the remainder and drilled it as big as I had (5/8) and then used an old trick. Heated the pin from the hole I just drilled. Not red but plenty hot, what maybe 750 deg F? Once hot, I then welded a bead in the hole, and then let it cool off. Basically welded the hole mostly shut. It ain't gotta be pretty but it does need to be a good weld. Then let it cool naturally. The pin then fell out. Welding the hole up shrinks the material around it ever so slightly. Down side is, i also had to do some painting.

Once I learned that welding causes shrinkage, i often used it on excavators to get the pin bushings out of the stick. Grab the mig, weld a bead on the id of the bushing, and pull it out usually really easily. Doesn't hurt the arm or stick. New bushing presses right in without issue.

actually just did it about a hour ago, pulling the ruined axle bearings out of an 8.8 Ford rear end. Bead on the remainder of the bearing, and they just fell out-literally fell out. Easier and faster than fiddling with the slide hammer.

Had an M series, loader pin was stuck tight. Had to cut that one completely out as nothing else worked.

Good luck.
