The Chelsea 489 Series Power Take-Off Assembly, part number 489ZWDAX-A5GK or 489ZWDAXA5GK, is an 8-bolt PTO built for most manual transmissions including Eaton/Fuller, Volvo/Mack, and Tremec applications. The integral 8-bolt cast-iron housing mounts directly to the transmission opening without an adapter plate, eliminating an extra potential leak path. Shift is wire/cable mechanical. The 1-1/4" round output shaft (with key) delivers up to 48 HP at 1,000 RPM, and the series is rated for 250 lb-ft intermittent torque. Strong tapered bearings replace needle bearings for greater load capacity. Internal parts are common with the Chelsea 442 Series, keeping serviceability straightforward.
