The Chelsea 489XCAHX-H3RK is an 8-bolt Power Take-Off unit from the Chelsea 489 Series, designed to bolt directly to manual transmission openings from Eaton Fuller, Mack, Tremec, and Eaton Endurant without an adapter plate. The one-piece cast iron housing eliminates the adapter plate leak path common to other mounting arrangements. The 489 Series delivers intermittent torque in the 201-300 lb-ft range and uses a wire/cable mechanical shift. Output is through a 1-1/4" round keyed shaft, and the series offers tapered bearings in place of needle bearings for greater load capacity. Typical applications include utility trucks, dump trucks, snow and ice removal equipment, and fire and rescue vehicles. Sold by Pro Gear and Transmission.
