The Chelsea 489QRLZX-V3XK is an 8-bolt Power Take-Off unit from Chelsea's 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 removing a potential leak path. The 489 Series delivers intermittent torque capacity of 201 to 300 lb-ft and uses a wire/cable mechanical shift. Output is via a round shaft with a 1-1/4-inch key. Tapered bearings replace needle bearings for greater load capacity. Common applications include utility trucks, dump trucks, and snow and ice removal equipment.
