C-100 Brake shaft seal - help please

[don from mystic 3]

My 1974 C-100 has developed a leak around the brake shaft.. Before I pull the drum Im hoping someone can supply the part number of the seal I need so I can have it on hand when I start the job. Many thanks.

You will find the illustrated parts list for your transmission here. Take the part number to the pined links at the top of the Transmission Section for reference to suitable replacements.

That is not an overly difficult job. Do a search in the Transmissions section - there have been many postings about what to do & not to do.

DO check the condition of the drum or shaft for excessive wobble first before you pull the seal. If there is any up & down or side to side movement, it is a complete waste of time & money to replace just the seal... Looseness means internal wear. In & out movement is OK

The bolt is right hand threaded but some thread-locker was used on the bolt from the factory. Heating the bolt up (not to red hot) will help get it moving. Be sure to use some blue or red thread locker when the bolt goes back in.

Back and forth left and right turns with a battery impact usually gets them moving. Or a six point socket with a breaker bar
