Welding crank to Pully? WORKED, FIXED, PICS!!
 

I wanted to start a new thread cause the old one was old as hell and now fixed as of last night.To sum it up without all the reading....

My crank pully broke off. Left the bolt in the crank. Extracted the bolt to see the key way of the crank pretty chipped.

The question is.. Can these two metals be welded together? I think the pully is cast iron and the crank steel I guess. Heres the original thread with pics.

UPDATE!!

So we go ahead and weld it up. Adam puts a weld on the key just to hold it in place.. Well the weld was big so the bold would not even go in the hole. Oh ----.. So he chips at it and the weld does not want to break. Screw it.. He welds a right around the whole thing. So Now I have 60 miles on it and its fine. There is some vibration coming from it.I assume the balance is now off at the crank and pully. My own thoughts are its going to eventually destroy the bottom end. Do I care, no. It was absolutely the best fix at the time. I am going to go all out on this car with a the original motor. Or the head at least if it does not go down with the ship. I took a video of it but I need to install vista to snag it off my camera. So should be up in the next few days.

Damm nobody knows if this would work? I am trying to git er done!

Re: Welding crank to Pully?
 

Yes it will work. not sure how the balance will be on it but ----, its worth a shot.

Re: Welding crank to Pully?
 

I think it was Sinner on here, or maybe somebody else, but they JB welded the keyway. I would try that before I welded the pulley right on.

Re: Welding crank to Pully?
 

I welded the key into the slot once, because it had broken a chunk out of the crank. It was either gamble on welding it in or take the motor out and apart to replace the crank. What's to lose?

It held up until I took the car to PepBoys for a cheap strut replacement, and they blew my motor.

I wouldn't use JB weld, because if you do that and it doesn't work, you'll be in all kinds of hell trying to grind it out so you can put a real weld on there.

im sure with a little grinding here and there you could balance that ---- out, all trial and error tho

Whoever this is looks exactly like buk.

Thats me. Right now I look like a terrorist since I haven't shaved at all.

Yeah one bit was broken doing it. Took about 15 minutes cause we we bullshitting. Took another 15 to weld up. I am pretty happy with the results.

Its pretty loud right now. Im not even trying to go into vtak :X

lol i hate brake rotor screws i was taking them off and the harbor gay frieght impact screw driver bit just broke inside one of the screws so i tried welding a blot to it and and unscrew it =fail
then drill taht took too long!!
thne i got a grinder and grinded the ---- out of the rotor cuz i was swaping in som other ones anyways car these werwe so badly worped
anyway good luck hope that sucker dont come flying off on you.. if it dose you should weld a single pully on there so u can run your alt.. lol or loose it completely and runa a magneto and carburator.. lol jk
