Sounds like the shaft is recessed too far below the securing bolt. Try removing shims from behind clutch flywheel/collet if you have any there. Seems like its shimmed too high above the shaft, so you're binding up the center bearings. Is it just binding or draggng the clutch bell against the clutch shoe?

That 0.5mm shim behind the collet is a standard shim size to start up, need NOT necessary the correct shim to place behind the collet, you might only need a 0.3mm or 0.4mm....

However, most of the engine should work with that 0.5mm shim, before you add or remove the shims, please make sure all the rest of the pieces are installed correctly and in the right position....make sure the clutch nut is tighten, also, make sure the clutch shoes spacer (the big round piece of spacer that has a counter sunk edge) is installed correctly, the edge should be facing toward the outside (GEAR) position......I had seen ppl installed that spacer the otherway, which made the clutch bell cannot spin freely...

If everythings are checked and the bell still cannot spin freely....you have too much shims behind the thrust bearing....remove 0.1mm at a time untill you have only 0.3-0.5mm space different like manuel said.

Yes that will be the cause of all your problems.

Is it the first time you built it?
What I mean is did the kit come incomplet?
If so you can call Serpent USA or Serpent Europe (depends on where you live) and they will sent you one for free, or pay you back the costs

If not, get a ceramic bearing as replacement, it works really well, and can stand the heat very well

Default Centax problems

Hi,

What you can also do is the following.

Yopu can take out the crankshaft of your engine, and then install the Centax clutch. This way you are sure the crankshaft isn't moving inside your engine.

Take it out very carefully! Install all the parts on it like you are supposed to do on your engine.
When this is done you can check if all the parts spin freely, by giving the clutch a swing. During this swing the crankshaft should be helt firmly so it can not move!

If this works you can take off the whole clutch (there is no crankcase yet) and assemble it on your rebuilt engine.

Try this, it worked for me.
