Lightbulb St170 auxiliary belt pulley

Hi,
I'm putting my ST170 back together after bending 2 valves
Now a pulley for the auxiliary belt is scrapping on the casing

Your missing an alloy spacer. These are a very snug fit and don't normally fall of.

Big wasa, do you know what the pulley is called? I can't seem to find it online.

It's just an idler.

It has a part number, I will try and fish it out. Give me a shout if I forget.
