The Chelsea 489 Series Power Take-Off Assembly, part number 489ZFDAX-A4XK or 489ZFDAXA4XK, mounts directly to the 8-bolt transmission opening on most manual transmissions including Eaton Fuller, Volvo, and Mack applications. The one-piece cast iron housing eliminates the adapter plate found on some installations, reducing potential leak paths. Intermittent torque capacity for the 489 Series reaches 250 lb-ft (339 Nm), matching the 442 Series. Shift is wire/cable mechanical. The output shaft is a 1-1/4" round with key. Shaft power output is 24 HP at 500 RPM and 48 HP at 1,000 RPM. Strong tapered bearings replace needle bearings for improved load bearing. Call us to confirm proper fit for your transmission.
