Hey Sam,
Yeah, I have thought about how it could happen....the way it was bent was to the side, I'm thinking that it was an axial load, not a radial. I don't think the bush could generate that sort of spinning force considering the clearance it has on the c/shaft shaft. A sideways load...?....I like your idea of an assembly oops
but could other oopsers (?:rolleyes
include:
Chain has been dropped off at sometime as the outside edge of the rear sprocket carrier has the outside edge rounded off
Cylinder head shows rubbing from cam chain (loose or broken?)
Piston has been 'smoothed off' and one oil drain hole below oil ring has been blocked off completely (looks like solid aluminium?)...been filed!
Piston ring lands are missing chuncks
Piston rings appear to have excessive side clearances
Cylinder head combustion chambers have heaps of dents
?....I'm wondering if she's had a piston lock-up at some stage (maybe causing the sprocket carrier/trans damage?), then the PO has done a half-hearted rebuild with race rings instead of the thicker std ones....and it was after this point that the circlip has decided to depart the groove (the circlip groove has been bent out on the side with minimal metal)
Always good fun to try and work out what has gone wrong with a machine when you pull it apart
Cheers,
Kev.
