Description
The Chelsea 489GQAHX-S3XK or 489GQAHXS3XK is a 489 Series Power Take-Off assembly designed for 8-bolt manual transmission openings, including Eaton Fuller, Volvo/Mack, and Tremec applications. The one-piece cast iron housing bolts directly to the transmission, eliminating the adapter plate found on some installations and reducing potential leak paths. Shift is accomplished via wire/cable mechanical actuation. The output shaft is a 1-1/4″ round with key. Intermittent torque capacity for the 489 Series is 250 lb-ft, matching the 442 Series, with shaft power rated at 24 HP at 500 RPM and 48 HP at 1000 RPM. Tapered bearings replace needle bearings for greater load-bearing capability. Sold by Pro Gear and Transmission. Call us to confirm proper fit for your application.
