gearbox oil change

[bossko]

Hi,

When changing the gearbox oil on a 172 cup are there any components or seals need replacing?

Cheers.

Drain plug washer.

Yeah like James said copper washer

There is a rubber seal on the fill plug, but that'll be fine to re-use as long as its not split or anything.

I never changed that just washer and no leaks yet what oil are u using.
