Lame Ass Question

And the question is, what exactly is crankwalk...i get that its a bad thing. I do know what the crank, i assume "walk" means it moves, but i wanna how and why?
Im totally confused!

i'm wonderin' too? it's not a term i've heard in my "honda habitat".

side to side or lateral movement out of spec of crank when running. obviously causes catastrophic problems. Check magnus motorsports. Very good explanation.

[LightningGSX]

The out-of-spec movement is usually caused by an excessively worn thrust bearing.

[npaulseth]

It's "caused" by the trust bearing wearing down.

EDIT: Jinx

cool makes sense. thanks.
