Black "Dust" in crankcase.

James A. Corbally /

When I removed my crankcase, I found that the inner surfaces were covered in a fine black dust. I'm assuming this is from the drive belt, but is this normal?

Actually, the title should have been "transmission case".

Sorry!

Re: Black "Dust" in crankcase.

I get lots of black dust from the drive belt on my Kinetic Magnum. Just wipe it off now and then, and keep an eye on your belt. The sides of my belt became worn sooner than I thought. If the dust gets to be excessive, that could be a sign that your belt is wearing fast.

Thanks for your reply, Peggy. I've a feeling it's wearing alright. 10,000K on the clock, run at high speed most of the time. Less than a year old, funnily enough!

I'll probably look into getting one of those Kevlar belts, and giving it a good clean before installation.

Thanks again,

James...
