The Chelsea 524 Series Power Take-Off Assembly, part number 524XUDBX-A-XK or 524XUDBXAXK, is a rear-mount PTO designed to eliminate clearance issues by utilizing the rear mount aperture available on select transmissions. The 524 Series features a compact two-gear housing with three speed ratios and pneumatic shift. Intermittent torque reaches 407 lb-ft, with continuous-duty applications calling for a 30% de-rate per Chelsea application guidelines. Output shafts conform to DIN 5462 and 4-Bolt DIN 5462 standards. Six shift options are integrated directly into the housing for a space-saving installation. Input adapters are available for ZF, Mack mDrive, Volvo I-Shift, and Eaton Endurant transmissions. Common applications include fire, aerial, refuse, tippers, and sewer and sanitation equipment. Call us to confirm proper fit for your specific transmission and application.
