CHELSEA part description

Representative Image and Description - The product image above and description below applies to all Chelsea Series 897 PTOs and is not part specific. Please verify the product using the part number.

Chelsea 897 Series was designed to fit the Allison 3000/4000 Series transmissions. This design moves the PTO/Pump mounting flange to the rear of the transmission for better pump clearance. All 897s have Wet Spline outputs for longer pump spline life.

Chelsea 897 Series Power Take-Off (PTO) is a constant mesh PTO for the Allison 3000 & 4000 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 897 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.
