Barnett Clutch install problem

[CptKirk]

I just bought a set of Kevlar friction plates from a Barnett dealer for my 86 VR XVZ13. When I received the plates two things confuse me. The shop manual shows index dots on the basket and index notches on the plates. These Barnett plates have no index notches on single longer tab per plate. Do I not have to concern myself with indexing or is something wrong with the plates.?

The other confusing thing is there are two green colored plates, one for either end of the clutch pack. One green plate is just as wide as all the other plates except it is green. The other plate is also green but is narrow compared to the others. Any idea which one is inboard and which is the outboard plate.

Barnett is silent on the subject and no help on their web site. Apparentlythey don't answer email questions. The dealer is equally silent. Both refer me back to the manual. And back at looking for index tabs, no mention of one narrow plate in the manual either.

 

Thanks for any wisdom.

Yeah there is a smaller disc in the original clutch, as I recall it goes in first and then the rest. Actually I thought the Barnett clutch had all full disc's but I could be wrong.

Why there is an inner and outer disc I don't know either.

Sorry I'm not much help but I usually use the clutches from Yamaha, they seem to be about as good as any.

I did try the upgrade recently but I can't say that I care much for that either.

After I post this reply I will look up a guys name for you to contact for help.

Got it opened up. Actually went well. I see the inner outer thing now. The inner is narrow. Dealer says no indexing needed.

Looks like you feel fit each friction plates you load it. Have a new release bearing and all the metal driven plates are like new. Was surprised to see no wear except the most inner one that ran on the thin inner friction ring. Have a new one to replace it with.Green plates are softer to run on aluminum final faces.

 

Barnett is no help though.

Think maybe this is the answer re indexing. If you take apart an in used clutch, you would mark each wearing piece so it goes together in a previously worn way. Surface against wearing surface.Built in indexes on stock plates let you do and undo without worry.

 

The Barnett plates would need to be marked to disassemble and reassemble if for some reason you needed to after it had been in service for a while. You'd need to index an in use clutch to put it back the way it was worn and not have binding.

 

The index is only for a used clutch?? Does that make sense.?

 

Wisdom welcome.

No need to be concerned about the index marks. When putting it back together with the new plates I checked for fit before sliding the plates into the basket. If the fit seemed sightly binding I rotated the friction plate one notch and tried again until a good fit was accross all the disks.I scuffed up the old pressure plates with scotch bright to make a new break in surface and installed two new plates to sub for slight marks on the two innermost ones.Having cleaned up the basket fingers of any old wear patterns by lightly filing them and installing a new throw out bearing I put it together and found no issues. Bottom line is don't worry about the indexing.The steel plates need to be oriented so that the sahrp edges of the pressure plates all face the same direction when installing. ( Sharp edges from the stamping process) I installed them with the rounded edges toward outboard.The clutch works just fine, better than new.No oil leaks either.Had I read more I would have seen the "don't worry about indexing" comment in a post on this forum.
