The Chelsea 880 Series Power Take-Off, part number 880XBAKP-H6XV or 880XBAKPH6XV, is an 8-bolt, lever mechanical shift PTO built for heavy-duty, high-torque applications. The output shaft is a 1-1/2" 10-spline with a 1410 companion flange. Intermittent torque rating reaches 500 lb-ft (678 Nm); shaft power is rated at 48 HP at 500 RPM and 95 HP at 1000 RPM. The cast iron housing offers long service life, and the removable shift cover makes backlash adjustment straightforward. Dual-pump output lets you mount a hydraulic pump on each end of the PTO. Compatible with Volvo/Mack, Allison, Eaton/Fuller, and other transmission manufacturers. Typical applications include fire trucks, bulk haulers, oil field equipment, aerial units, winch systems, and large recovery trucks. Call us to confirm proper fit for your transmission.
The Chelsea 880 Series PTO fits most manual transmissions with an 8-bolt aperture and is designed for high-torque, high and low speed applications with constant mesh input gears. Tapered cone bearings provide strong load-bearing capability. The removable shift cover simplifies backlash adjustment during installation. Applications where this unit is commonly specified include product blowers, fire suppression rigs, oil field pumping, aerial lift trucks, and large-capacity recovery and winch vehicles. The 880 Series supports output configurations including SAE B, SAE BB, SAE C pump flanges, ISO 7652 pump flange, and driveline outputs across the broader series range.
