Tonight I decided to started cleaning up the 4 speed, and dissect the leaking Muncie P2HX PTO.

I've read seal replacement is fairly easy on these units, but I'm looking for the pointer in the right direction!

I have it to this point...

Need I remove the shafts to pull the seals? And if so, how??

As far as I know the seals are
- Timken 480821 or Chicago Rawhide 7474
- Timken 480889

but I can see a national number one, 50800.

Thanks
Mark
