how to remove this pin?

[RunningaDeere]

Hi All,

I'm new here, and have a 2004 110tlb. It's been a good machine, I bought it new, used it for land improvement projects, and my life changed; I let my father use it. He never greased it. I've got a frozen pin, that I need to remove, and it appears to have a smaller rolled pin holding it in. I'm not sure if it's just a friction fit, or is it threaded in? I tried running an screw driver through it, but it hits solid from both top, and bottom; is that normal, or is it packed in dirt/rock/grease?

I've pulled the zirc a few times, and sprayed with penetrating oil, but it won't allow any in. Any suggestions would be appreciated.

It looks like a hex or allen head bolt to me in the pic.


The large hole in the bottom, is that where the grease fitting is?

That's why I stopped, it almost looks like an allen. I asked on another unrelated forum; they're thinking it's a split pin, that expands to hold pressure. Their advice was, assuming it's a rolled hollow pin, was to run a smaller drill bit through it, to break out whatever is solid, then using heat to force the pin out. I think I'll see what I can do with a small screw driver first, to knock out what may be in there.

What you're looking at on the bottom, I think is where you'd place an appropriate sized punch to knock out that rolled pin; just guessing..... The actual zirc is in the middle of the pin; out of view.

Possibly a taper or roll pin.
I'd be very tempted to attempt to drive it out from the other end with an appropriate punch.

Using a drill bit is a tricky chance to take if it is a roll pin as the drill bit will shatter and then you are in the dodo.
If it were me I try driving it out first. Just be sure to use the largest punch that fits that hole.

You might try different positions of the components to get most of the weight off the main pin- that might be putting the roll pin in a bind. I have a grease zerk on my hoe that will not take grease until the weight is off of its part of the pin; then it slurps grease with ease.

Can’t remember all the details about the time I couldn’t tweek the boom position well enough to get a pin in or out- it either was too high or too low. I finally put a bottle jack under the bucket and jacked it up to the right height while I was down there on the ground with it, not up in the seat.

It sure looks like allen head to me . My best guess is it is threaded into the solid plate with the remainder of the bolt not threaded but extending into the large pin .

Here is a diagram of the bucket and dipper stick, go back and look at the HYD clamp section also.

If that is a roll pin it should be split and easy to see the split, If that is a allen head it could be rounded out.
Clean the pin/allen head with a wire brush and take us a pic up close.

If that was a roll pin you would be able to see the edge of the hole it's inserted into, that really looks like the head of a bolt that covers the hole entirely. just saying

If you have a JD dealer, go in and buy a replacement for the "unknown" pin/bolt. Then you'll know exactly what you have, and you'll have a spare.

Took awhile to find it, but am thinking it is the quick coupler, and they are "spring pins" key #7. Could not get 1010's link to open. So drive them out..
