Roll pin removal---Any advice or tricks

[Soundguy]

easy.. don't cut the hub.. cut the race..

if you adjust your torch correctly, you know exactly where it cuts at...

the welding trick is the ticket though. as the race cools it draws and shrinks the OD

just don't weld tru to the hub.

use low penetration rods.. like a 6013 on ac, and low amps. just want to draw a bead around the inner face of the race..

In some cases I have even use that technique to shrink the ID of a splined tapered sector steering arm so it fit a sector shaft better / farther out.. etc. that and pounding ont he flat open face of the arm-hole will shrink the ID and expand the od.. etc.

lotsa tricks...

What if I only have a MIG and torch, am i out of luck with the welding trick? Its a Pro MIG 175 by Lincoln.

Thanks

why would you be out of luck?.. I think it will likely be easier with a mig.. even a flux job.

What the others have said, but also get a roll pin punch set. not the same as a drift pin punch.. notice the little round end that goes in the hollow of the roll pin and still has a sharp shoulder. This is to help from "peening the pin to the inside hollow space" if that makes sense.

Wow! Great advice, I did not even know such a set existed.

Amazon is currently sold out, but Newark has them:

GRIP ON TOOLS|61135|9 PC ROLL PIN PUNCH SET | Newark.com

SK tools also makes a set, but for SK quality/name they are about $40 more than the Grip set.

Personally I use a hammer first to drive the pin in if it is sticking out, then I use as big of a standard punch as I can get in the hole to start it. Then use the proper size pin punch to drive it out. Be sure the punch end is flat, and hit it hard the first time.

hit it hard the first time./QUOTE]

Making that first hit hard is very important!:thumbsup:

If you try cutting with a torch, how do you not damage the hub? I only had lots of sparks flying when I tried cutting metal with the torch. I'll have to give the welding idea a try next time too.

Theres a visual change in the sparks that I have been told about. I wont be trying it. Put a weld bead on and shrink it out for me.

Hitting the pin directly is an error large or small. There is much more risk of deforming the end with a direct blow. Something in between will aid alignment and make it less important to strike perfectly. Use something fairly short and fat so the energy of the blow is delivered sharply. A 1/8 -1/4 thick piece of strap metal works well ... then its punch time.
