The Chelsea 489ZUDAX-A3XD or 489ZUDAXA3XD is an 8-bolt power take-off assembly from Chelsea's 489 Series, designed to mount directly to manual transmissions including Eaton/Fuller, Volvo/Mack, and Tremec equipped with an 8-bolt PTO aperture. The integral one-piece cast iron housing eliminates the need for an adapter plate, removing a potential leak path. Output is through a 1-1/4" round shaft with key, and shift actuation is wire/cable mechanical. Intermittent torque capacity for the 489 Series is 201-300 lb-ft (301-400 Nm), with shaft power rated at 24 HP at 500 RPM and 48 HP at 1,000 RPM. Tapered bearings replace needle bearings for greater load-bearing capability. Internal parts are common to the Chelsea 442 Series, making service straightforward. Call us to confirm proper fit for your specific transmission and application.
