Unfortunately it seems to be the previous owner wot did it! The bolt was glued in!If you still have the broken bit, metal glue and shape a penny washer to suit, and glue that under bolt head
Yes thought I might have to. It was wet as I took it apart in the rainI'd change it for peace of mind, plus it looks a bit wet around there so it may be leaking anyway?
Yes I wish I knew! Got one ready to go on Fleabay but the seller is asking which way the pulleys rotate as it's for a clockwise rotation. Surely if it's a standardised number ANR2157 itt's for that engine?They aren't massively expensive, I'd replace it. God only knows how you break one in the first place.
