Prop Hub O-Ring

[Knucklez]

I’m going to be replacing the front seal on my O-360. When I have the Sensenich prop off, I’ll replace the prop hub o-ring. Does anyone know the size of the o-ring needed? I’d like to have a couple on hand, just in case.
Thanks again folks.

It is a Hartzell part, sorry but I do not know the size. But if the prop is off, it is a good idea to replace the alternator belt.

I plan to replace the belt, and wrap a spare around too. The mechanic on my field, seems to be a master at that.
