Default wiping out clutch bearings

I'm using werks clutchs and i'm going through clutch bearings in 2 heat races.I've got plenty of play in the clutch bell.Going to try some ceramic's to see if that works .Don't understand why this is happening.I figured there would be less heat generated by using werks,But i know that this sucks and will cost me an arm and a leg if i can't get this resolved.I really like the clutch but not if it's going to do this to me everytime!

On clutch bearings you are just better off paying more for the ceramics.

I don't think ceramics will solve your problem. If they are going out that quickly there is an issue. Possible causes are wrong mesh(too tight), worn/loose spur gear, wrong shimming, mud or dirt in the teeth of the spur gear/bell, engine bearings going out, chassis flexing too much(usually a cracked chassis), and heat related problems. That's all I can think of off the top of my head.

Does your crank have any runout?
And also check gear alignment.

The clutch springs might be too stiff causing your clutch to slip and generate too much heat. I had the same problem with burning out clutch bearings in my 8ight T and it was because of spring that were just too stiff.

What I was saying is that spring might be too strong and not allow your clutch to engage soon enough to keep from slipping at low to mid RPM's. That would generate more than enough heat to destroy a set of clutch bearings.

Take that Werks clutch set-up and throw it in
the trash. Get a three or four shoe clutch set-up
and your problems with clutch bell bearings will
go away.

Make sure motor is mounted square to the spur gear.

Are you running that clutch on a werks motor? I had problems with clutch bearings when I ran a werks motor changed over to a Alpha and havnt had a problem in nearly a gallon. It also has to do with alighnment. make sure your motor is square and not cocked, If its cocked even a little it will eat bearings also.

It could also be the crankshaft is worn down so the clutch bell wobbles like crazy. It happens on mostly older engines or when you've had bearings sieze up or go out and the crank is out of round as a result. If it's the werks clutch with the adjustable spring that goes over the crank, it can loosen up while driving, if it's the newer werks clutch that's like the losi system it should be fine...give the gear mesh a bit of clearance as chassis flex can bind up the mesh if too tight....
