WORN OUT CLUTCH BELLS SUCK!

When you're having too much fun running you fifth-scale gas truck/car hard, clutch shoes wear out down to the metal. When they do and you're unaware of it, the bare metal of the worn-down shoes begins to grind down the area in the clutch bell where it makes abrasive contact. From then on, it's metal grinding against metal which you can often smell.

And how does this affect your vehicle's performance? Well, you might find that even after installing a new clutch it loses acceleration at full throttle. That's because the clutch shoes at full expansion cannot make full contact on the inner surface of the bell because much of the surface there is gone.

(The first picture shows a worn clutch bell. The second shows the obvious wear in more detail: the shiny part that's been worn down from a shoeless clutch and the darker part that constitutes the natural surface where the bare metal of a worn clutch did not affect.)

So, what's the moral of this post? Simple, if you drive your vehicle hard, be prepared to change your clutch often or you'll have to change your clutch bell as well. And it adds up.

PEACE!

I still find it crazy the clutch bell and shaft are no longer one piece. I put a new one in mine a few months ago. I thought it was the wrong bell. So far its holding up. I was a bit concerned seeing that tiny cross pin expecting it to break. Guess that is the fix to shaft breakage which I've broke 2 or 3 already.
