Chelsea 878 Series PTO Units
The Chelsea 878 Series is a constant mesh (non-shiftable) 10-bolt PTO for Allison 3000 and 4000 family automatic transmissions. It shares its design and its parts manual with the Chelsea 871 Series PowerShift PTO, but it has no shifter: the PTO output turns whenever the transmission's PTO drive gear turns.
