What's on your bench today?

That is a relatively unusual one. I have seen the gudgeon pin wear and not the piston before...I think Nepias 262XP had that a few years back. It always seemed strange that the pins steel wore rather than the alloy of the piston.

I would check out the big end cage to make sure it is OK, fit a new small end or at least inspect it and fit a new Meteor piston, if available.

Whilst you are at it....fit a new clutch drum bearing if the drum has a bit of wobble, most don't and I have written of a few machines for worn crank shafts - new ones are ££££.

Oh...make sure the missing pin is retrieved and if you can't find it, flush the bottom end out, check inside the muffler and then double check all the transfers and ports for nicks and bruising of the edges.

It was the same with the phosphor bronze bushes on the swinging arm of old british bikes, the steel shaft wore, that I put down to grit getting embedded in the bronze and grinding the shaft, With a chainsaw small end the gudgeon pin shouldn't rotate in the piston, the movement should be in the small end bearing.

The only time I have seen that was with a Chinese cylinder and piston on a 357xp and it was the piston that wore not the  Gudgeon pin.

Nepias 262XP was the gudgeon pin that wore as was an 064 a few years after. The 064 just had a spare gudgeon pin fitted to repair it. Both were OEM top ends.

When I said gudgeon pin wear I meant it has worn piston. Cylinder and piston were replaced only 2 years ago because gudgeon pin retaining clip broke and scored cylinder and piston cheap part used. 

Have found meteor kit so will fit new top end.
