Are you talking about the soft, almost rubber-like gear? If so, that's the same gear that failed in mine. NH speedo tells me that gear is designed as the "weak link" for a reason (same principle as a fuse or cb). It is the first gear to disentegrate so that other gears don't chew themselves up in the case of a drive problem.

I'm sure also, as you said, that these gears disentigrate over time in a perfectly operable speedo. Sounds like you've got it figured out - just wanted to share with you what I came across..

btw - thanks for the link; the same guys I almost purchased from - the $25 for that 1/16 of a nano-ounce part pushed me over the edge to sending it in.
