The Chelsea 489XSAHX-V6RK is an 8-bolt Power Take-Off (PTO) unit from the Chelsea 489 Series, designed for most manual transmissions including Eaton Fuller, Mack, and Tremec. The one-piece cast iron housing bolts directly to the 8-bolt transmission opening, eliminating the need for an adapter plate and reducing potential leak paths. The 489 Series uses tapered bearings rather than needle bearings for greater load-bearing capability, and shares internal parts with the 442 Series. Shift type is wire/cable mechanical. Output shaft is a 1-1/4" round shaft with key. Intermittent torque rating 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. Typical applications include utility trucks, dump trucks, and snow and ice removal equipment. A genuine Chelsea part, sold by Pro Gear and Transmission.
