The Chelsea 489DFMAX-V6RK is an 8-bolt Power Take-Off 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. This unit features mechanical wire/cable shift, a 1-1/4" round keyed output shaft, and strong tapered bearings for greater load capacity than needle bearing designs. The 489 Series supports intermittent torque in the 201-300 lb-ft range and shaft output of 24 HP at 500 RPM or 48 HP at 1000 RPM. Common applications include utility trucks, dump trucks, and snow and ice removal equipment. A genuine Chelsea part, available from Pro Gear and Transmission.
