Thread: PAS box leak

My 110 has a leak at the the top cover plate of the PAS box- i assume there is a seal/o-ring under there that i can replace in situ-don't really want to have to to pull the whole thing out to replace one seal. BTW-is it possible to get just that seal/o-ring or do i need to buy a whole kit?

Is it a Gemmer or an Adwest box?

The Gemmer uses the following cover seal: BAU4865
The Adwest Heavyweight (3-bolt) box uses: RTC295
The Adwest Lightweight (4-bolt) box has two seal kits available for the sector shaft:
To (V) MA 955519 - STC1042
From (V) MA 955520 - STC2848
