I have been using the BUKU composite shoes and a Robinson racing clutch bell but the clutch-bells teeth still bend or strip :angry:, the teeth alignment is good and i used the paper trick, is there an extra super strong clutch-bell for the savage xl 5.9, or a way to prevent this from happening - i get about 4 or so tanks and then the teeth bend and crap out. :angry:
 
what kinda spur gear do you use?
maybe a bearing is iffy on the bell?
maybe a cracked motormount or plate. or missing screw
 
Use a stock spur and the bell will last forever:D.

In order to chew up a RRP clutch bell you must be using a steel spur, the only way you can chew up a clutch bell is the mesh was off to start with or it moved (for whatever reason) while you were running the rig.
The only way to prevent the issue from happening again is to find the problem and fix it.

FWIW, I never recommend the "Paper Trick" In most instances the mesh usually ends up too tight. You’ll be better off in the long run if you learn to Set it to the listen and feel method. You should feel a slight gap/lash and hear a slight tick when to hold the bell stationary and rotate the spur against it with your finger. Do this around the entire diameter of the spur.
 
I've always used the cheap plastic spur gears, easy and cheap to replace if there's a problem.
 
I am using the stock spur gear

I have used the stock clutchbelll but the teeth bend on those too
 
One thing for sure, the stock spur isn’t chewing up the bell. You would be hard pressed to find a bell harder than the RRP bell.

You need to figure out what’s chewing on the bell teeth… Got pics of this?
 
I was thinking it could be the power of the car is to much for the clutch bell with the hard accelerations

Do you think that this could be because of the spurt gear being so thin
 
Is this a new savage xl 5.9, if so then it already has a hardened steel spur gear. O.P give HPI hardened steel-vented clutch bells a try. < was recommended to me by DreamMachines.

I have had my fair share of RRP gears for my savages and they are garbage, I was also bending and tearing teeth out of the RRP clutch bells, it would start at the C.B then begin on spur.

Once and only once did the bearing fail in my RRP spur, and the same as above happened, except the spur was the part missing teeth, but both had spots where the teeth were flattened.
 
This used to happen to me your spur gear nut is to tight.tighten it Down and back of it 2 turns and u should be fine
 
^^ if this is for me it is quite possible, since the second RRP spur didn't fail, but was damaged by the stripped clutch bell, now the last one that I have, and the last of my savage RRP spurs is still holding on, but I don't run the .25 that much. It's getting harder to keep it in .25 parts as time goes on.
