The Chelsea 524 Series Power Take-Off Assembly, part number 524XMACX-F-XK or 524XMACXFXK, is a rear-mount pneumatic-shift PTO designed for vocational trucks running ZF, Volvo I-Shift, Mack mDrive, or Eaton Endurant transmissions. The ISO 7653 80mm x 80mm mounting interface (Mounting Option X) attaches to the rear mount aperture of compatible transmissions, helping to clear tight under-cab or mid-chassis spaces. Output shaft options include DIN 5462 and 4-Bolt DIN 5462 flanges. The 524 Series two-gear design delivers 49-57 HP (37-40 kW) at 100 RPM output shaft, with continuous torque rated up to 300 lb-ft (407 Nm), verify ratings against the application pages for your specific duty cycle. Six shift options are integrated into the housing, and the dry-spline output (Lubricant Option X) keeps maintenance straightforward. Common applications include fire apparatus, aerial units, refuse trucks, tippers, and sewer and sanitation equipment. Call us to confirm proper fit for your transmission and application.
