Chelsea 899 Series Power Take-Off (PTO) is a
constant mesh (non-shiftable) PTO for the Allison 4700 transmissions
that provides better clearance with the highest torque rating in the
industry – up to 670 lbs-ft. It fits neatly between the transmission
and the frame rail of the truck and locates the pump output to the
rear of the transmission for adequate space. It mounts like a
standard side mounted PTO but includes an additional bracket at the
rear of the transmission for support. The 897 Series is a single
unit, not a PTO with an extension. The main shaft is one-piece shaft
eliminating the input splines between the PTO and the output
extension. The pump interface is located at the rear of the
transmission to allow the housing and gear section to tuck in
tightly to the transmission for improved clearance. The output
utilizes Wet Spline Technology which extends PTO and pump shaft life
in demanding conditions. The 899 Series can be ordered for
transmissions with or without a cooler or retarder or both. It is a
perfect PTO for aerial trucks, fire & rescue trucks, snow & ice, or
anywhere pump space and high torque is required.
