I have a cam with a bent dowel pin that needs to come out. Anyone have any suggestions on successfully removing it without having to drill it out or needing to buy an expensive specialty tool?

I'm rather disappointed comp uses these butter soft pins in their cams - a hardened pin only costs about 75 cents.

I've hung mine by clamping the pin in the bottom of a bench vice and then hit the nose of the cam with a dead blow hammer. Be sure to catch it or have it land on something soft. Why did the pin bend? Did the cam bolt come loose?

The pin was damaged during shipping, not from a loose cam bolt.

I'll try the vice grip/bench vice trick first. Probably doesn't hurt to put some heat on the pin at the same time to loosen any possible locktite. If that doesn't work, I may tack weld a nut or bolt on the end of the pin and put a slide hammer on it.

Pulled one out last night with a good pair of vice grips locked onto the pin really good, then a smack with a hammer on th side of the grips knocked it loose and I worked it out with the grips after that. I let it sit in penetrating oil all night before as well, it was a really old B cam install on a neighbors car and he had upgraded to an Xe cam and trick flow heads.

I got it out by clamping the pin in the vise and smacking the nose with a brass hammer. There was almost a thou press fit on this thing, which is ridiculous. I ended up drilling the hole out slightly and installing a hardened 5/16 pin. It has just enough drag that you can't pull it out with your bare hands without loctite applied.

Thanks again everyone for your input!
