Loader BX23 bucket pin removal.

[pipefitter]

Embarrassingly, I never greased the pins on the bucket. The grease zirk is on the bottom, and it lubes the pin from the center. I never noticed it. The the bucket has some "slop" in it, so I bought a pair of pins, (PN 75532-58740), from a local dealer. I've removed the grease fittings and been spraying some kroil around the pins in an attempt to loosen things up, but they seem pretty stuck. I wondered if anyone had removed theirs?

I don't claim to be smart, but I can't see how sloppy pins can be stuck. Do you have a picture?

It sounds like you're saying they won't slide out.

Did you remove the pin retainers?

The pins are stuck. The slop is where they attach to the loader itself. Apparently, they are seized in the bucket, and have worn the attachment points at the loader. I will get some photos.

Yep, they're gone.

The pins are bound up on both sides of the bucket weldments UGH.

You are going to have to have the bucket weldments and the cylinder
rods line bored and new bushings installed.

Short of hiring a welder to come and use a rosebud torch to heat the
cylinder rod eye and use a bronze punch to drive the pins out of the
cylinder rod eye and bucket weldments or having a couple of carbon
dioxide fire extinguishers on hand to chill the pins to make them shrink
after you empty one fire extinguisher on each pin and driving the pin out
with a 4 pound hammer I do not see much else working for you.

Better to just send the mule to the kubota veterinarians(UGH-I hate my local dealers)
and have them remove the pins and line bore the cylinder rods and bucket weldments
as replacing them will also cost a great deal of money.

I would get an estimate for having the cylinders and bucket line bored before you do
anything else as the damage done is irriversable with out line boring.

It sounds like the bucket itself might be fine if you could get the pins out, but then you would have to deal with the cylinder's egg-shaped bore. If you could get the pins out and replace the cylinder rod, you might save some loot and avoid line-boring.

The rod is about $260 at Coleman's. You could rebuild the cylinder while you have it apart. The kit is $108.

I had two stuck pins on my mower, and I tried rigging up a large pulley puller to push them out. It didn't work for me, but maybe it would work for you after some heating and so on.

I'll post some pictures as I think I'm confusing everyone. I *think* the pins are seized in the brackets on the bucket, as they move with the bucket as it's tilted. I only have a cylinder in the center of the loader, so it should be fine. It appears that my options are going to be removing the bucket, grinding the pivot points on the loader off, and welding on new ones. I have a machinist buddy that can make the pivot points, (weldments?), and I can weld them. Anyhoo, I'll try to take some pictures today, and I appreciate all of you for replying.

Had to replace the bushings and pins in my BX2200 loader years ago. They are just welded on the out side of the loader arms. Once the bucket is off the weld can be ground, off the bushing removed and a new ones installed. Hard part is line reaming the arms to get a straight fit and drilling the hole for grease zerks to do their job getting grease to the pins.
I rednecked mine but a good machinist would have better tools and skills than I do.

I had the cylinder rebuilt recently for my BX-22 and replaced the pins. Fortunately, they slipped out without much force which I'm thankful for given the 70 ton of material I had moved with it when doing the groundwork for my shop building. It does sound like you may need to do "plan B" and replace the brackets if brute force can't get things apart. At least you have the resources and skills to do that.
