Roll pins

[Dave]

Any tricks to remove a broken roll pin. I have tried everything I can think of or look up on the internet. It isn't moving. I hate roll pins.

Yeah they’ve give me fits before on a batwing mower pto shaft.
I’m sure you’ve tried this but a long narrow punch and hammer or sledgehammer.

I’ve drilled them out before. Not much fun, but can be done.
Were you able to get any of it out?

 

[RDFF]

Is it rusted in place? Guy that worked in an engine reman shop told me that it's common in their industry, to get rusty manifold bolts loose, to heat with a torch and then apply paraffin wax, sucks it up in like solder in a sweat joint.

Do you have actual roll pin punches? Better yet is pin punches for an air hammer.

That and some heat.

 

[jltrent]

Heat, and/or punch, or drill as mentioned. If using a punch, try to get one just a very little tad smaller than the hole. I always get them out, but some can be a pita. Put vice grips holding the punch and hit with the biggest hammer you can swing with one hand. If I can get it in my 40-ton press something will give.

Roll pins are like striped screw heads. It is best to use the proper tool in the first attempt than it is to hope for the best.

Roll pin punches are your best bet but they should only be used for roll pins. If you batter the ends on other jobs they will not work well either.

Can you post a picture of it ? Depending on its location and access to getting it out. Might be different ways to attempt getting it out, Some might work better than others.

I second the roll pin punches and a punch handle to hold them with.

I third that. I’ve used a short bolt the right diameter, too.

 

[CowboyRam]

I had one that would not budge, even with heat. Maybe I didn't heat it enough. I ended up getting on of those palm nailers and finally got it beat out.

I wouldn't have thought of that. I have one, but just haven't ever used it really for that kind of thing. Smart! Learn something all the time on here! Thanks.

I tried heat using a hand held little propane torch. I am thinking about rolling the cutting torch out there and use some real heat. There is a tractor mechanic I will see at church tomorrow. I am going to pick his brain.

Little hand held propane torch does not concentrate the heat. It’s a matter of heating one part much more than the other. Possibly could melt the roll pin out, hard to explain, but often, if you’re careful, can separate one piece from another by melting without damaging the shaft. Also have to consider heat damage to nearby seals. As others have stated, use the correct size pin punch. Sometimes can grind the pin flush, then start over, important to not mushroom or expand the roll pin with too small a punch.

A hand held torch doesn't provide enough heat to really break rust. A oxy fuel torch puts concentrated heat on one part quickly to cause expansion/contraction and break rust bonds.

I will do that. The roll pin is on my flake feeder. I will have to wait until there is no hay on it to use the torch. About every 4 days or so I have to hook up the battery charger. No hay when I do that so probably Tuesday.

Your flake feeder is only pretty new Dave, I wouldn't have thought that things would be that seized up in that period of time. Are you sure it is a roll pin and not a grub screw?

Yes I called up the man who builds them. I was looking at the other one trying to figure out what I was dealing with. He said it is a 2.5 inch 3/8 coiled roll pin. He said if I couldn't find a new one I could use a grase8 bolt to replace it. That is what I plan to use.

Make sure that you fully support the piece the pin is in. Bounce will eat all the force you apply to the punch.

I presume it is thru a shaft. It would take a lot of force to shear that pin. Was any other part of the flaker damaged?

 

[Dave]

How to best describe it..... Note the vertical pole with the black fins. The shaft inside it turns helping to both hold the hay from falling out uncontrolled and also to flake it off. The one to the right is the one with the broken pin. No pin allows the part with the fins to slide down the
shaft. Picture 2 shows the left one with unbroken pin. Picture 3 is the broken pin.
This is the middle of January and I have been feeding every day for about 2 months with it like this. The feeder still works. One of those it is not wrong but it is not right deals.
