Crank pully sanity check...

[21TonyK]

"My" common sense says this is knackered. The cracking means the pully has slight movement when you press it and it rattles a bit.

If I'm wrong and its cosmetic tell me before I order a new pully and belt....

I'm not familiar with that engine, but that would concern me too.

I'd be changing that.

Another pulley for comparison, also well used but nowhere near the amount of crackage, https://www.ebay.co.uk/itm/135318227597
