The Chelsea 524 Series rear-mount PTO assembly, part number 524XVAHX-A-XV or 524XVAHXAXV, is a pneumatic-shift power take-off designed with a ZF input adapter for direct transmission mounting. The 524 Series uses the rear-mount aperture available on compatible transmissions, eliminating common clearance problems with a compact two-gear housing. Three speed ratios are available within the series to suit different application requirements. The series-rated intermittent torque reaches 407 lb-ft (300 lb-ft continuous before de-rate), with output power of 49 to 57 HP at 100 RPM on the output shaft. Output flanges conform to DIN 5462 and the ISO 7653 80mm x 80mm mount standard. Common vocational applications include aerial, refuse, fire, tipper, and sewer-and-sanitation trucks. Call us to confirm proper fit for your specific transmission and application.
