Gasket Replacement

Honestly with quite a few a-833 under my belt, only leaks I’ve seen over 35 years in this hobby is leaking tail shaft seals. Just buy a new gasket kit And bearing kit from Brewers and call it a day. If your forks are brass and still in one piece you can upgrade to steel. And unless your doing a complete rebuild due to metal in the bottom and oil or broken parts, those transmissions are really good pieces. JMHO.
