The Chelsea 877XGKVP-M5RF is a constant-mesh power take-off from the 877 Series, designed for 10-bolt Allison transmission applications with high-torque, continuous-duty requirements. The output shaft is a 1-1/2" 10-spline configuration with a 1410 companion flange. Continuous torque rating reaches 670 lb-ft (check application pages for verified torque ratings). Shaft power is rated at 64 HP at 500 RPM and 128 HP at 1000 RPM. The compact housing reduces installation clearance issues, and rotatable output flanges allow additional positioning flexibility. Wet Spline Technology is integrated to extend service life at the PTO-to-pump shaft interface. Typical markets include refuse trucks, aerial units, snow and ice equipment, and fire and rescue applications. Part also referenced as 877XGKVPM5RF. Call us to confirm proper fit for your application.
Common application markets for the 877 Series include: refuse trucks, aerial equipment, fire and rescue trucks, snow and ice vehicles, pumper cleaners, oil and gas equipment, and defense vehicles.
Eight internal gear ratios within the series provide speed flexibility across a wide range of hydraulic system requirements. Pressure lubrication is integrated into the PTO housing, requiring a single hose connection for installation.
