If you look, you can see a couple of spot welds on the inside of the cone where the factory must weld the outer pully to the inner. I would think a die grinder may be able to grind them out. I have a four groove that I was going to try this to, but I am not sure if the other grooves will line up with the water pump and alternator.

I tried with couple big screwdrivers just now i can wiggle the outward pulley very tiny bit and is slight gap up on the neck where bolts to dampner but not enuff to get anything in there id like to put it in a vice and put a pipe wrench on the neck give it a pull just enuff to see if it would twist but dont have a bench or vice here lol maybe if i slamed it hard against a tree?lol ok just kidding nothen else sooner or later it will meet the lathe 1970 barracuda convert. 1 of 59 1970 pro street A.A.R. clone (panther pink) 1971 charger 2015 hellcat challenger.

I would not thought so but when we had a 4 groove pulley in the lathe (it was a pretty decent pulley not all rusty) to make 2 groove out of it..... We had the groove section in the chuck and was cutting the neck(needed a shorter neck) all was going good then was rusty smoke and loud scream from the pulley it just twisted right off we looked it all over and no welds of any kind it was just pressed togeather i would of thought it would of been welded also but in that case it clearly was not lol then i caught hell from buddy....

Once I drilled out the 5 or 6 spot welds on one & it still wouldn't come apart so I would avoid that Last edited by RapidRobert; 01/19/12 01:13 PM. live every 24 hour block of time like it's your last day on earth

Worked fine, spins fine, dosnt woble either. I dont see why you couldnt do the same on a crank pulley. Kasey
