The Chelsea 880XMAHX-P3XS or 880XMAHXP3XS is an 8-bolt power take-off assembly from the Chelsea 880 Series, built for high-torque, demanding applications including bulk haulers, fire trucks, oil field equipment, aerial units, and large recovery trucks. It uses a lever mechanical shift and delivers up to 500 lb-ft intermittent torque (678 Nm). Output is through a 1-1/2"-10T spline shaft with a 1410 companion flange. Shaft power rates at 48 HP at 500 RPM and 95 HP at 1000 RPM. Compatible with Volvo/Mack, Allison, Eaton/Fuller, and other 8-bolt manual transmissions. The 880 Series features constant mesh input gears and tapered cone bearings. Available from Pro Gear and Transmission. Call us to confirm proper fit for your application.
The Chelsea 880 Series PTO is suited for oil and gas, aerial, mining, on-highway, and other mobile equipment markets. Typical applications include bulk haulers, winch systems, fire trucks, oil field equipment, aerial platforms, and large truck recovery rigs. Constant mesh input gears support both high-speed and high-torque demand cycles. Tapered cone bearings handle heavy radial and thrust loads. The removable shift cover simplifies backlash adjustment during installation. The 880 Series is also available with SAE B, SAE BB, SAE C, ISO 7652, and DIN 5462 pump spline output options depending on the model configuration selected. Cross-reference: SP880XMAHX-P3XS.
