The Chelsea 524XVAAX-A-XK is a 524 Series rear mount power take-off designed for vocational truck applications. Rear mounting uses the transmission's rear aperture to reduce clearance conflicts that front- or side-mount units can cause. The 524 Series features a compact two-gear housing with three available speed ratios, pneumatic shifting integrated directly into the housing, and an ISO 7653 80 mm x 80 mm mounting flange with a dry spline output. Input adapters are available for ZF, Mack mDrive, Volvo I-Shift, and Eaton Endurant transmissions. Common applications within the 524 Series include aerial, refuse, fire, tipper, and sewer and sanitation equipment.
