Looking for a p/n or crossover for a replacement APEX PTO/Clutch seal. The seal behind the primary, on the reduction shaft, yammy doesn't show it seperately, and they want 600 bucks for a complete shaft! This seems a little crazee for a seal that can be taken out by a blown belt. If anyone has changed or had this seal changed, please let me know where you sourced the seal from, or what the solution was.
