524XVACX-F-XV Chelsea 524 Series Rear Mount PTO

The Chelsea 524 Series Power Take-Off, part number 524XVACX-F-XV or 524XVACXFXV, is a rear-mount, pneumatically shifted PTO designed for vocational truck applications including refuse, aerial, fire, tippers, and sewer and sanitation work. It mounts via an ISO 7653 80mm x 80mm interface and ships with a dry-spline output configuration. The DIN 5462 or 4-Bolt DIN 5462 output shaft delivers 49-57 HP (37-40 kW) at 100 RPM output shaft speed, with continuous torque rated at 300 lb-ft (407 Nm) - verify actual torque against Chelsea application charts for your specific installation. Input adapters cover ZF, Volvo I-Shift, Mack mDrive, and Eaton Endurant transmissions. Six shift options are integrated directly into the PTO housing, and the unit features a quick-assembly sealed bayonet connector for the indicator switch. Call Pro Gear and Transmission to confirm proper fit for your truck and transmission combination.

Additional Information

The Chelsea 524 Series uses a two-gear design to keep the housing compact, which helps resolve clearance constraints at the rear of the transmission. Three speed ratios are available across the series to suit different hydraulic pump and accessory drive requirements. The sealed bayonet connector on the indicator switch simplifies installation and reduces service time. Direct-mount pump output flanges allow two pump configurations without additional adapters. This series covers a wide range of vocational markets including aerial, fire, refuse, tippers, and sewer and sanitation. Refer to the Chelsea 524 Series application pages or the applicable owners manual (general: HY25-1501G-M1_US; ZF: HY25-1501Z-M1_US; Volvo/Mack: HY25-1501V-M1_US; Eaton adapter: HY25-1501E-M1_US) to confirm torque ratings and application-specific requirements for part number 524XVACX-F-XV.
