Adjusting a 47 Clutch system.
 

I've kept my truck all original so I still have the old clutch system on the rattlebox. The clutch was replaced but I was curious if anyone with a bit of knowledge had any tips about correctly adjusting the clutch.

My reason for doing so is it is either the clutch needs adjusting or I have some hot spots on the flywheel. I can only assume it was turned when the clutch was replaced last year... but I did not do the work so... we'll start from the start, thanks in advance.
