The Chelsea 524XVASX-V-XK or 524XVASXVXK is a Series 524 rear mount power take-off assembly with pneumatic shift. Designed for vocational truck applications, this PTO uses the rear mount aperture to help eliminate clearance issues common with side-mount configurations. The two-gear design delivers a compact housing, and three speed ratios give flexibility across duty cycles. Output power runs 49-57 HP (37-40 kW) at 100 RPM output shaft, with continuous torque up to 300 lb-ft (407 Nm) - check application pages for actual torque ratings for your setup. The ISO 7653 80mm x 80mm mount and dry spline lubrication are built into this configuration. Input adapters cover ZF, Volvo I-Shift, Mack mDrive, and Eaton Endurant transmissions. Call us to confirm proper fit for your application.
