anyone ever BEND the dowel pins on their cams???!!!
 
My belt slipped and so after I set the belt back in place and went for a spin, it was no better. It wont rev past 4500. so I dug a little deeper and when i pulled my cam sprockets, I saw the pins were dented and bent!

has this happened to anyone?


:eek5: pics soon...

One would think that bending a cam dowel pin would be significant of mechanical interference... :eek:

yep bent the dowel on my talon's cam while trying to loosen the bolt that was holding on the sprocket. You'll need a new cam for sure.

except i wasnt tightening or loosening anything. if it happened when i changed the cam belt, would it not have shown its face before the 20000 miles i rode in the meantime? hmmmm ....

correction, I remember now I stupidly used an impact gun on those nuts! i'll post some pics on my solution.

here is one of the bent pins. Can someone tell me if there is a notch in these or that's just my talented use of an Ingersoll Rand 2131?

my solution was to weld a tack onto the bent dowel, file it down and voila! Back in business.

That's from a loose cam gear- put a torch on it and pull it out. Then install another one. Lots of machinist supply houses stock dowel pins. I wouldn't rely on weld to hold something that's loaded like a dowel pin.
