Constant Mesh (Non-Shiftable) 10-Bolt Power Take-Off (PTO) - 899 Series
Brand: Parker ChelseaChelsea 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 lb-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.
