The Chelsea 489 Series Power Take-Off Assembly, part number 489XFAHX-A3XR or 489XFAHXA3XR, is a wire/cable mechanical-shift PTO with an 8-bolt mounting configuration designed for manual transmissions including Eaton/Fuller, Volvo/Mack, and Tremec applications. The one-piece cast iron housing bolts directly to the transmission's 8-bolt opening, eliminating the need for an adapter plate and reducing potential leak paths. The 489 Series delivers intermittent torque in the 201-300 lb-ft range and output power of 46-55 HP. Shaft power rates at 24 HP at 500 RPM and 48 HP at 1000 RPM. The 1-1/4" round output shaft with keyway accommodates a wide range of PTO-driven equipment. Internal components are common to the Chelsea 442 Series, and tapered bearings replace needle bearings for greater load-bearing capability.

The Chelsea 489 Series PTO is suited for aerial, vocational, and municipal equipment applications including utility trucks, dump truck and trailer, snow and ice removal, and fire and rescue vehicles.
