Best way to remove UJ roll pins?

[Lonestar]

Hi Guys

what's the best way to remove the thick roll pin that keys in the rims on the old rc10's UJ's? I had one stuck on a car I'm working on right now, and it took much more efforts than needed to remove it, I eventually had to start drilling it to be able to push it out with such technique that involved a vice, a hammer, and many cusswords that my mom would be very ashamed for her son if she ever heard them... Ideally next time I'd like the process to be smoother

thanks for the help,

Paul

Paul, First I use a pair of medium sized channel lock type pliers to push the pin out as far as I can. The jaw of the pliers is slightly offset which allows me to rest the lower jaw against the pin while the top jaw pushes the top of the pin through. I then use a pair of needlenose pliers with a near 90 degree bend in them grasping the pin with the end and rocking the plier along the length of the axle for leverage. The pin usually will come out that way. It has been suggested on this forum that crimping the pin down a little before reinsertion will keep you from having to deal with this any more. Hope all that is clear, I don't have pics right now.

I hope this helps and you can find one. It is a pinon puller fo slot cars that I ground down one side of , it slips but I have had good luck with it

I use a small finishing nail or something. Smaller than the hole in the axle, but bigger than the inside diameter of the pin. Lightly tap with a hammer and it'll come right out.

thanks for the help all - sorry I let this thread die, thank you for keeping posting great info

yes, getting one of the ends flush with the axis is the easy part (multigrip pliers do the trick) but it indeed becomes tougher after that. Pushing it with an external length of metal is what I did, but even then it's a challenge as it's hard to secure the axle in a vice without damaging it.

mmmh pinion puller, I should have thought about it myself!!!

thanks all the for the good info,
Paul

if you have a vice, just grip the pin in the vice jaws after you push it all the way to one side, then rotate the axle back and forth while pulling up on it, it will walk the pin right out of the axle. Squeezing on the pin should also make it easier to remove and install in the future.

This is what I started with and it was a miserable failure. the pin wouldn't move the slightest, and I was going to bend the whole assembly (hubs were attached)... I could pretty much move my whole workbench that way!!!

yep - I wish the guy who built that worlds car 17yrs ago had done it that way I'll keep that in mind for the rebuild

Here's a pic of the type of pliers I use. You can put a lot of force on the axle shaft with these babies. I think this method has only failed me once on a very corroded pin.

mmh I used first a leatherman and then later on some chunky industrial multigrip pliers... and it wouldn't bulge - not a hundredth of an inch anyways, I got it out by pushing it so we're good. I'll get it right next time

thanks!
