Thanks Dennis. Annoying how Bentley is not quite forthcoming on that one.

I know I have to get the pulley part seal off. I’ll give it a go. I have another , non Syncro , pulley as back up .

Thanks again,

Alistair

If you look at the rear of the pulley you will see where the o-ring sits. It has to be installed on the crank, past the key before the pulley goes on. The dimension is critical so that it goes into that cup without getting pinched. The part number is N90078401.
