sticking clutch?

[kahless]

i have a real problem. i strip out a clutch bell about every tank of gas.i have checked the adjustment and have tried it loose and tight. it starts out running fine but then after about ten minutes it strips out the bell. i am wondering if maybe when the clutch gets warm it is not slipping like it should. is there a way of testing this? i really need to find this problem as the new clutch bell is 20 bucks a pop.
i have an Alton nitro heat
4x4
2 speed tranny
.16 motor

the clutch i have been told is very heavy duty, it is twice the thickness of a t maxx and i can only find parts for my truck at my lhs. Any thing else i should check? :shrug:

have you taken it down to the lhs and asked them?

How familiar are you with RC? The reason I ask is, if you don't know how to set proper gear mesh or not. Or maybe the engine is cockeyed a little bit.

I'm not sure I quite understand this. By stripping out your clutch bell, do you mean the inside of it is getting messed up? Are you stripping the teeth off it, or stripping the teeth on the large spur gear?

i am not very familer with rc but i am learning, and it is stripping the teeth off the bell, i upgraded the spur gear when i kept stripping it out now i am loosing the gears on the bell.
I will check the engine but i am sure it is nor cockeyed, i have been told by my lhs how to set the gear mesh and i have tried it loose and tight with the same results. so far i have chewed up 5 spur gears before upgrade and 6 clutch bells after i upgraded the spur gear

What did you upgrade your spur with? I just had a similar problem on my maxx. I bought a spur from RC-Solutions that was made out of super hardened steel and I chewed up a CB in about 1 tank of fuel. The CB I was using was a heavy duty HPI CB that was made to run with plastic spurs. It may be heavy duty by being thicker, but it may still be soft steel. You may want to look around for a hardened CB.

I don't recognize the truck, but Robinson Racing Products makes 1/10 clutchbells for other trucks that are hardened steel. You might want to try one of those.

Stripping teeth as you described will come from 1 thing, gear mesh.
Why is your mesh fluctuating or not proper?

Not set properly.
Broken motor mount.
Chassis flex.
Bad bearings.
Bad installation of bearings.
Bad installation of spur.
Miss-alignment of engine.
Wrong parts.

Something is causing the mesh to fluctuate or not be proper to begin with. Finding it may be difficult. Set it up and look at it. Move the parts. Flex the chassis. Look at it again. Keep looking, and look again. With the issue a blatant as you say it is the cause should be obvious if you just look and think. Did I say you should look and think.

Don't give up, you will find it and learn something along the way.

What about the pitch you are using? Is one metric and the other SAE?
I seem to remember that there's a pitch # that's the same, but one is metric and won't mate up with the SAE spur. Check them both.
