Deburring keeps debris out of oil, reduces wear and extends life of clutch basket and hub

Makes for smoother starts when letting out the clutch lever too.

Basically the stamped-steel clutch plates are mass produced for lowest cost, so no de-burring is done. So the much more expensive-to-replace aluminum hub teeth and basket fingers get worn down like a corn cob when the burrs bite into their soft metal everytime the clutch lever is pulled and released. All those little bits and shards of aluminum end up in your oil--not what i want in my baby...

A carbide bit in the dremel works great, but it will cut thru steel (and fingers) like butter so use care. i use the carbide to cut the burrs and chamfer the edges, then use a small hand file to break and blend the corners.

 

Looks more like the carbs (cylinders) were not sync'd very well. Lets the crank oscillate back and forth because of minute uneven firing banging the steels and plates in to the basket. Or visa versa if you want, banging the basket in to the plates. I guess another possibility could be a lot of bangin gears all the time.

Replaced my clutch at 50k miles and my basket had very little if any wear on it.

 

Never even thought about that, the deburring, but it does make sense. really how much would it cost the factory to do it at the time? Less than a buck? either individually, or in a rotating drum with other parts and some shot.

but at home would recommend one of the sanding abrasive stones in the Dremel not as fast to cut, so you can be a little more ham fisted

 

I have found the best way to work on repairing a clutch basket is with a file. Of course you only a step away from replacement.

I have to admit that the last one that I had to file was on my 7 year old 71 triumph twin.

I don't think burs are at fault in the one photoed. Is that a vfr clutch?

 

Then ya got the story about Rolls-Royce buying a Hydramatic tranny from GM and it wouldn't work. GM has it sent back and the Rolls dudes have "cleaned up" one of the mechanisms in the tranny that was supposed to be rough. Whoops..

Some clutches are dry too..

 

.......jeez!! one more thing to worry about.

 

I wonder if any dentists have done this when they aren't seeing patients?

 

This whole issue may turn into a sales pitch for some new kind of oil filter.

 

I know that the baskets cost a lot, but I think I'd just replace all of that at once.
