The Chelsea 524 Series rear-mount PTO assembly, part number 524XUDAX-A-XY or 524XUDAXAXY, is a pneumatically shifted power take-off designed to mount at the rear aperture of compatible transmissions, helping eliminate clearance issues common with side-mount configurations. The 524 Series uses a compact two-gear housing with three available speed ratios and delivers up to 407 lb-ft (552 Nm) intermittent torque with an output power range of 49 to 57 HP at 100 RPM on the output shaft. The ISO 7653 80mm x 80mm mount (X-option) and dry-spline output (X-option) are integrated into this unit. Input adapters for the series are available for ZF, Mack mDrive, Volvo I-Shift, and Eaton Endurant transmissions. Common applications include fire, aerial, refuse, tipper, and sewer and sanitation equipment. Call us to confirm proper fit for your specific transmission and application.
