DOWELL PIN REMOVAL

[BIGBLOCKHEAD]

Hey guys...my stroker project needs a steel dowel that presses into the block on the pass side that aligns the block plate and C6 trans.  It is just missing and I wonder how one removes one of these from a core engine without destroying it in the removal process.  Any tricks?

Drill from behind & knockout with a punch?

There are special tools to remove them, but the average person won't have them. You could try heating around it and twist with a pliers/vice grip. You could try the punch and hammer from behind like mentioned above also. Usually, they don't come out without some kind of damage. May not be worth the effort. I have used these here. Well worth the $3.49, IMO.

Most any machine shop would have 1/2" dowel pins, they only cost a few cents. Press fit in block, drive out from back side, use a drift punch and a good size hammer. Dowel pins are hard as the hubs of Hell, you can't drill them!

I had to remove one from a side-oiler block.  Heating and Vice Gripping didn't begin to get it out.

Using a Dewalt hand drill and WD40, I drilled and tapped the dowel to accept the male threads on the end of a slide-hammer.  On about the 3rd or 4th pull of the slide-hammer, it popped out.

I once had to change a tire on a car with wheel locks. The lock was hardened. I put a torch to it and heated it good, and then grabbed it witrh Vise-Grips. Since I'd heated it enough to soften it, the VGs grabbed and it came right off.

You could do the same thing with a hardened dowel.
