All you have to do is make sure the pins and mains are clocked properly and spin true. :thumbsup: Quote Link to comment Share on other sites More sharing options...

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 Link to comment Share on other sites More sharing options...

BB3 Posted May 21, 2008 Report Share 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 Link to comment Share on other sites More sharing options...
okbeast Posted May 21, 2008 Report Share 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 Link to comment Share on other sites More sharing options...

BB3 Posted May 21, 2008 Report Share 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 Link to comment Share on other sites More sharing options...
bunboy1 Posted May 21, 2008 Report Share 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.

Leadfoot350 Posted May 22, 2008 Report Share 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 Link to comment Share on other sites More sharing options...
