Keyed Crank vs. Welded

[Arizonaduner]

I've wondered about keyed crankshafts before (Vs welding) and I just ran across one at Vito's performance. It would seem to me that going with a keyway would be a better way to go but they are outnumbered 20:1 compared to welded cranks.

Anybody have experience with these? Any thoughts?

The one in the picture looks severly bent lol. I'm not sure what they mean by Keyed? Is that like the stock crank? Coulden't you say the stock crank is Keyed and Pressed but can still seperate? I dunno man but I hope you get an answer.

the stock crank's webs are not keyed, however the PTO and flywheel mounts are.

Is it being suggested here that Vito's is keying the crank pins? If so, that is near dumbest thing I have heard this month................

That's what I thought was going on. Did I miss something?

I guess that's what I thought too....................until I read the ad at the link that was posted. All the Vito's deal is, is a key in the center main into the two inner webs. Which is nothing special.

 

I would prefer welding to the key deal, especially if the keys are in line with each other, which would lead to major stress risers, right where you don't need them.
