[novalew]

sorry for the silly title was pretending to be funny

but honestly i've just found this 140169090248 (ebay item)

can it just be tightened?

is it worth anything?

It doesnt look like the thread is damaged, but if the pully wheel slipped due to the pin dislodging, you may end up with valve damage.

If you get it for a tenner, got to be worth a punt imo.
