So I finally got round to getting my flywheel off (which was surprisingly painless after I tapped the new threads), and I found all these fragments of .. something .. sitting at the bottom of the clutch housing: 
(I'm just holding it there for scale.. I have no idea whether or not it's meant to live somewhere around there) Does anybody have any idea where these might have come from? Cheers, Harry |

HARRY33 (I'm responding so I get a reminder) I gotta know too!!!!!!! When I stripped my 850 for the rebuild, I had almost the same bits. I asked around and no one could tell me??? I had enough bits to make a circle, but couldn't find where it broke off. I eventually put the new clutch in and everything seems alright.?? Watching with interest,,,,,//// Alex. |

I'm only guessing, but surely someone hasn't tried to "shim" the primary gear end float?? Cheers Shane |

Cheers Shane Correct, actually not uncommon. |

I've never heard of that being done! that said, I have a modified primary gear in my engine (has been there for the last 12 years) and we had to put dobs of weld on the C washer (then surface ground flat) to push the other bit closer to the bush |

Seen a couple, and had one myself for a while, no worries at all. The shim should be a full circle though, I really can't see how one gets torn up and spat out - I'd suggest there's something else going on to cause that (i.e something wobbling that should be). Slightly off topic - also saw a master seal today installed backwards - also no problems. Bit of oil in there, but no clutch slip! A series have their issues, but in their own way they're also pretty damned forgiving! |

Shimming is not a great idea there. I have built up the outer washer with nickel bronze then machined to size in years past, that works well. But usually you can fix it with new parts- bronze inner thrust washer, outer stepped washer, and C-washer. |

Agree, not a great idea. But infinitely more accessible to the home mechanic than some other options.
