BigRed350x Posted December 12, 2006 Report Share Posted December 12, 2006 As stated above, the pin that holds your connecting rods is welded to the outer web. It prevents the crank from pulling apart when you start to bump up compression and timing. Its also a safety thing you should do to any crank to prevent it from comming apart anyway. You will need a TIG welder to do it yourself. A competant machine shop and do it for you no problem. Here's one I welded up last night at work... Nothing really too fancy. Its going in a stock stroke, stock compression bike that won't ever see anything higher than stock-ish compression so these welds will be plenty for it. On other cranks that will see a lot more compression and timing I use a little more heat to get better penetration. Quote Link to comment Share on other sites More sharing options...
okbeast Posted December 12, 2006 Report Share Posted December 12, 2006 Is that really all it is when they talk about welding the crank? Wow, I always thought it was alot more to it. Quote Link to comment Share on other sites More sharing options...

You can weld the inner web as well, but yeah, that's pretty much it. Quote Link to comment Share on other sites More sharing options...

badassbanshee479 Posted December 12, 2006 Report Share Posted December 12, 2006 you should have the crank checked to make sure its true if you have ran it for any length of time! my buddys crank was out of phase by 14 degrees, in other words the crank had spun on the pin and the rods where not where they where suposed to be!! and also make sure you weld all the pins! inners and outters! I had one come apart and it made a big mess of things! Quote Link to comment Share on other sites More sharing options...

BigRed350x Posted December 12, 2006 Report Share Posted December 12, 2006 (edited) Thanks for the compliments guys. I'm no professional by any means. I know enough to get by and that's about it. :beer: Yes, you should weld the inner AND outer webs if you get it done. This crank was trued before I welded it. There's some other pictures of different welding I've done, especially on the frames, in other parts of the HQ.

chevy7398 Posted December 13, 2006 Report Share Posted December 13, 2006 i just pulled my crank out cause it was in need of a rebuild, long story short cheapest rebuild kit i could find $291 chapest labor to rebuild $120, total $411 not counting welding, brand new hot rods crank trued and welded from f.a.s.t. $400 plus shipping, not to hard of a decision to make if you ask me Quote Link to comment Share on other sites More sharing options...

Like I said. Damn good job buddie. Wish I could weld like that. a good way to spot a really good weld is looking for splatter... if there is any splatter the welder either isnt very experianced or has the wire feed speed wrong or the power is off.. also the amount of metal on the weld should be slightly raised and even across the weld... and to check the technique, it should looks like half moons linedup in a row. anyone can weld... but welding right... now thats an art!

I'd say its more experience than anything else. The more you do it the better you get at it. I play around with welders almost on a daily basis some weeks. I'm no pro, but I'm pretty happy with what I can do on my own. I know I save myself a lot of money doing my own work most times. Quote Link to comment Share on other sites More sharing options...
