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?

 

[RunningaDeere]

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..

I'm with 1010 on how to approach it. Clean it up (preferably with solvent and soft brush to preserve evidence of stripped hex) to see if it's split or if head look's to be stripped. If it isn't split,it's not friction fit which mean's threaded. If threaded with stripped head,I'd clean up and weld the largest grade 5 bolt that will go inside. Air impact will loosen better than wrench but heat from welding will likely ease removal. If bolt snap's off,grind flat,weld on a nut and have another go at it.

Deere calls it a spring pin (#7), punch and hammer time!

 

[RunningaDeere]

I think we've got a winner; so it's driven out??? I did talk with a few heavy equipment guys, they said those get welded in often; which may necessitate burning out the larger pin...

 

[RunningaDeere]

Hey, I really appreciate the help with this to everyone! I'll be working on this early this next week; wish me luck!

If it's a spring pin, it means there's a hole completely thru it. On bigger ones like that, I've used an acetylene torch and a good, clean tip and burnt the pin out. If the main pin is rusty, which it probably is, you won't burn into provided you get in and out fast enough...........Mike

To make roll(spring) pin removal easier you need to acquire a roll pin punch. Mayhew is a very good brand of roll pin punches.

This was my thought too, buy several, I'll bet that's not the only one hung up.

 

[RunningaDeere]

Thanks for the responses, I'll get on this Monday. I'm going to check into Mayhew punches. I talked with one heavy equipment guy, he said they usually like to replace them with a graded bolt, and 2 nuts to lock. He said they usually end up burning through them, as they get stuck.

Another possibility if the large pin is frozen. The roll pin may be sheared off and the hole in the pin may not be aligned with the spring pin hole in the frame. You might try driving out the large pin first to see if it moves. If pin is frozen, lots of persuasion may be needed! (torch)

Gotta love TBN! Talk about service. :drink:
