524XTASX-V-XK Chelsea PTO Assembly

The Chelsea 524XTASX-V-XK or 524XTASXVXK is a 524 Series rear mount power takeoff assembly with pneumatic shift. Designed to fit ZF, Volvo/Mack, Eaton/Fuller, and certain other transmission applications, it uses the rear mount aperture to help eliminate clearance issues that side-mount PTOs can present. The ISO 7653 80mm x 80mm mounting pattern is encoded in the part number, and the output shaft meets DIN 5462 or 4-Bolt DIN 5462 specifications. Continuous torque is rated at 300 lb-ft (407 Nm); verify actual torque limits against Chelsea application pages for your specific installation. Output shaft power reaches 57 HP (40 kW) at 1,000 RPM. The dry-spline lubrication designation means no grease is used at the output spline interface. Call us to confirm proper fit for your transmission and application.

Additional Information

The Chelsea 524 Series rear mount PTO assembly is built around a compact housing and offers three gear ratios. Mounting through the transmission's rear aperture rather than a side port helps resolve tight underhood clearance situations common in severe-service vocational trucks. The dry-spline output design eliminates the need for periodic spline lubrication at the output interface. Torque ratings are application-dependent; always cross-reference Chelsea application data for your specific transmission before installation. Cross-reference numbers for this unit include 524XTASXVXK, CHE-524XTASX-V-XK, and CHE524XTASXVXK.
