Just wondering how often do people replace clutch bearings - do you replace them each raceday or wait for them to shatter themselves?
I should probably start taking note of when I change them and how long they are lasting to :wink:

Cheers,
Mark

but from a race point of view, id change them every hour of use.

I went through a phase of breaking them every 2nd time i drove mine !
I reckon heat is a big killer,along with dust.If your engine is running real hot,or your clutch bell has real worn teeth it'll shorten the life of your bearings.
I put a new clutch bell in,and started using rubber sealed bearings.Now i just change them every 2 meetings or so - piece of mind and all that :)

What sort of bearing is it? Are they an oddball size? Are you buying cheap and nasty or a quality name brand item?

Im using some that we get in from A Main Hobbies (http://www.amainhobbies.com/product_info.php/products_id/5725). They seem good as far as I know. Havent had any problems with them (I just had no idea how long a clutch bearing is normally ment to last :wink: ).
Cheers,
Mark

Thats cool, if they are a standard bearing used by Kyosho they must be sweet. I know that some bearings can have a lifespan measured in minutes when the going gets dusty and nasty(Yokomo diff bearings for example)
