Thanks Norm,

I'm still struggling a bit here.

How did the conrod wear a groove in the flywheel? Surely they are on opposite sides of the bearing and seal? I wonder what caused that to happen? Bearing shot perhaps?

Do either of those pulleys need a separate boss? The PT one on the right looks very thin ( maybe pressed metal,) without the interfrence fit cone that fits over the flywheel.. Is the PT pulley much different to the FC?

Having never seen either, I'm having a little trouble grasping the concept. Mine is very different.

Thanks for your patience.

All the best
Jeff
