Cleaned my mates sump out and this is what I found.



Anybody got any ideas, made of hard plastic.

poss gearbox spacer or oil shield not 100% though is it def plastic and not oil glaze (colour looks like old oil that has baked hard then broken away ) shape makes it look more like a part ..just looked at exploded view of gears and crank no plastic washers etc prob not much help but hi anyway and good luck

Thanks for the reply tractor, it's definitely not metal, some sort of plastic I am guessing. I have looked through all the parts pictures and can't see anything similar. Needs somebody who has rebuilt one of these motors to cast their eyes over it.

I should have put a scale in the pic, the diameter of the circle I have arranged the bits in is about 70mm.

Hi Gazz,
Never Seen a plastic ring,Like tractor sayz is it baked oil from a burnt clutch, it looks clutch diam, previous owner may have tried to pack a worn clutch with a plastic ring to stop slip enough to sell the bike on!

Hope it isn't a packer!! It appears to be that colour all the way through, I'll take a close up with a better camera tommorrow and post it up, perhaps somebody dropped it in by accident, whatever it is, when they did a rebuild!

Here is a better pic, it's plastic. Any other ideas?



Gazz

That looks like it's worn on all the edges? Are all the pieces like that?

Hi Jaicen, yes all the bits are like that, any ideas as to what it is?

Gazz, i d'nt think its suppose to be in the engine, was it the SP? maybe they are different than standard but i d'nt think so. Maybe they put it on the SP box or clutch but they d'nt usually put plastic parts in the motors. I not long ago rebuilt a gk73 and there is no plastic in the motor anywhere.

Chris, I feel the same, goodness knows what it is and after looking through the 76a parts diagram again I'm pretty sure it's foreign. Thanks for looking guys.
