Hey guys,
Can someone please help with the inner diameter and thread pitch of the nut holding the crankshaft pully. I am busy assembling the engine, seems that the thread got damaged or I have the wrong nut.

Thank you.

My pulley (JTD) is held on by 4 Torx screws which are M7 and standard pitch.

What engine have you got?

Yes, I would ask what engine too. However I'm wondering, as the question states the engine is being reassembled, whether it relates to the crankshaft sprocket bolt itself - not the little bolts that hold the aux belt pulley onto it?

I seem to recall that the nut on mine needs a 22mm socket.. and it's a fine-pitch (possibly super-fine?) for sure .

If so then it's an M14.... but as for the pitch, I have no idea.
