The Chelsea 877 Series Power Take-Off, part number 877XAFJW-M5RY or 877XAFJWM5RY, is a 10-bolt constant mesh PTO designed for Allison transmissions. The output shaft is a 1-1/2" 10-spline with a 1410 companion flange. Continuous torque is rated at 670 lb-ft (908 Nm), with intermittent torque exceeding 501 lb-ft. Shaft power measures 64 HP at 500 RPM and 128 HP at 1,000 RPM. The compact housing reduces clearance issues, and rotatable output flanges allow installer flexibility. Wet Spline Technology helps extend the service life of both the PTO and the pump shaft. Typical applications include refuse trucks, snow and ice equipment, aerial units, and fire and rescue vehicles. Call us to confirm proper fit for your application.
The Chelsea 877 Series is engineered for demanding, high-torque continuous-duty applications including refuse trucks, snow and ice equipment, aerial units, and fire and rescue vehicles. Pressure lubrication is integrated into the PTO housing and requires a single hose connection for simplified installation. Eight internal gear ratios provide flexibility to match virtually any application speed requirement. Note: Parker lists the 877 Series as an obsolete product line. Pro Gear and Transmission can help you confirm availability and identify any applicable current-model alternatives - give us a call.
