The Chelsea 489 Series Power Take-Off, part number 489XSEVX-A3XQ or 489XSEVXA3XQ, is built for 8-bolt manual transmission applications including Eaton Fuller, Eaton Endurant, 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 delivers intermittent torque in the 201-300 lb-ft range and uses strong tapered bearings rather than needle bearings for greater load capacity. Output is through an SAE B 2 or 4-bolt flange with a 7/8" 13-tooth SAE B shaft, rotated 90 degrees. Shift type is air shift. Common applications include utility trucks, dump trucks, snow and ice removal equipment, and fire and rescue vehicles. Call us to confirm proper fit for your transmission.
