Roll pin removal---Any advice or tricks

[jonyyuma]

Absolutely! I've had to drill out pins because someone else decided to give it a go with a regular punch and only managed to make my invoice larger. Another point is to remember to use the exact right size when replacing them, especially in conditions that are subjected to vibration.

Agreed, plus a little heat from Mapp gas if not easy enough or refuses to move?

If it has been mentioned excuse me, and I know you said you were going to use penetrating oil but I would highly recommend you use PB Blaster. Squirt it on the offending pins the day or even days before, maybe a couple of times over days, a little dab will do ya. I saw it in home depot recently... That stuff is amazing...

Got that already. Good stuff!

PB Blaster is good and I use it because its easy to get but I have also used Kroil but Kroil can only be ordered from the manufacturer (well, unless things have changed). I just have been too lazy to order it but now that winter is here I may order some more now. Price isn't bad either.

This may be a stupid question, but I am restoring several old implements that have been sitting outdoors for decades. There are lots of roll pins or what you may call spring or split pins. They look like a hollow cylinder with a slit. These are firmly rusted in place. Obviously I use a penetrating lubricant first. Is it best to just hammer them (which tends to brad the end), use a punch (which also brads the end), or what? Any tricks to getting these out so I can disassemble the parts? Is there a trick to removing these old locked up pins?

Exactly, use it for the jobs you know are going to require the most work I learned at an early enough age to use the best penetrating fluid available. Its been great since PB Blaster has become more widely available. It use to be the only thing you could find locally was WD-40

 

[Soundguy]

yup.. I used to work at a water meter factory / foundry.

wd40 is what they gave us.. it was junk.

I remember trying liquid wrench thinking diesel fuel was better.

I love pb, and also make my own juice from time to time with a solvent like kero, diesel or mineral spirits, with one or more of the following, naptha, acteone or hexane, maybee isopropyl, and then a lube, like type f trans fluid..

that frees up most stuff on the cheap.

the kroil, is for when I've already broke 1 stud off and have 7 more to go..

The proper punch and a big hammer have a tendency to help in the removal process.

Thanks for the good advice. I ordered the roll pin punch kit and have plenty of PB Blaster and a big hammer. I am getting ready to disassemble an old Allis Chalmers 4 row planter to restore. I think I know know enough to start breaking it down.

Please help me remember my physics. Any tips on using heat to free stuck nuts or pins? I assume you heat the nut or the part with the hole where there are pins in place. I guess I can use my acetylene torch with a cutting tip to heat a nut, as long as I don't fire up the oxygen. Or is a rosebud better? How hot do you try to get the frozen parts? Any danger from heating parts where PB Blaster has been used as long as there isn't any excess pooled? I guess any deep in the threads cooks off quickly. Any advice would be helpful. Thanks.
