Re: Metallic scoring noise when clutch engaged
Hi, Craig, The sequence of re assembly you quoted isn't the same as the manual, however the sequence you used could be used when replacing the seals only to save removing the cover. In the manual the primary driven gear and clutch outer basket are assembled together in the case first, then the case...

Re: Metallic scoring noise when clutch engaged
Hi If the clutch basket socket cap screws are too long it will cause the problem you described. They should be 22mm as measured on a dismantled engine of known provenance. They must not protrude out of the driven gear. M6 x22 is not DIN912 standard by the way. 20 or 25 are standard. Mark Hi Mark Yo...

Re: Metallic scoring noise when clutch engaged
Hi Norbert, the bevelled edge of the washer is definitely facing the bearing and no loose studs. Any further thoughts gratefully received. Thank younorbert wrote:Are you sure that there is none of the studs loose?
The washer behind the primary is mounted the correct way, the reduced face towards the bearing?

Re: Metallic scoring noise when clutch engaged
Not sure I'm thinking this through right, but have you missed out the thrust washer with the 4 ears between the clutch inner and outer drums? That is there to deal with the lateral movement of the primary gear and clutch outer drum assembly. Hi Steve Thanks for the reply but the nylon thrust washer...

Once rebuilt with the assistance of the workshop manual, parts catalogue and Paul Compton's videos I now have a disturbing scoring/grinding noise that only occurs when the clutch is engaged. It is ...
