Bigger maintenance and question

[Brummel]

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

Replace what's needed, as needed.
