Hi again 
I have to run a bigger maintenance on my LC 100 1999er V8. Has took us now 330000km.
Timing Belt + Serpentine Belt + Radiator Replacement (leak) + Fuel Filter and some pipes + all oils (ATM, Diffs, Engine)
Exhaust Muffler already replaced
As I have plenty of parts purchased, I recognized a pully in a diagram (lower right) just now. It caught my attention not before. Part Number is 16603-50030 ( don't know what is this for)
I guess I need this pully as well when doing all others right?
Thank you
Marcel
