Just a serious tack at each crank pin end, acts just like a tight keyway to prevent twist. I have seen a cranshaft welded all the way around & the bearing bosses were not concentric. There was 0.010 TIR because of too much heat (weld) input. Quote

Animalman294 Posted March 26, 2008 Report Posted March 26, 2008 Good to know I thought it was welded all the way around, not tacked.............. Quote
BB3 Posted May 21, 2008 Report Posted May 21, 2008 No need to balance. All you have to do is make sure the pins and mains are clocked properly and spin true. :thumbsup: Do both side's of the pin's need welded inside and out or just the outside? Thanks Bobby Quote
okbeast Posted May 21, 2008 Report Posted May 21, 2008 Passion did mine and I'm pretty sure there's a weld all the way around. Now I know different guys do it different ways, I was just saying. Quote

BB3 Posted May 21, 2008 Report Posted May 21, 2008 So is this something i can do with out a problem? The crank i have was just rebuilt but was not welded. I was thinking i would go ahead and weld it up since a shop rebuilt the crank and i am hoping it is trued. What do you guys think? Quote
bunboy1 Posted May 21, 2008 Report Posted May 21, 2008 i just installed a hot rods +4 mm crank. i recall seeing a weld on the crank web, when i pulled it out of the box. does this crank need to be welded a 2nd time or not? any thoughts? thanks. Quote
Leadfoot350 Posted May 22, 2008 Report Posted May 22, 2008 I had a shop do my stock one and they did a pretty good tach job and well it crack the weld so you have to do more than a tach Quote
BB3 Posted May 22, 2008 Report Posted May 22, 2008 Ok cool Thanks every one i will be welding the pin's up tonight. Quote
