The Chelsea 489 Series Power Take-Off, part number 489XLAHX-X5RK or 489XLAHXX5RK, is an 8-bolt mechanical shift PTO designed for most manual transmissions including Eaton Fuller, Mack, and Tremec. The integral 8-bolt cast iron housing bolts directly to the transmission opening without an adapter plate, eliminating a potential leak path. The series delivers intermittent torque in the 201-300 lb-ft range and output power of 46-55 HP, with a 1-1/4" round keyed output shaft. Strong tapered bearings replace needle bearings for greater load-bearing capability. Typical applications include utility trucks, dump trucks, and snow and ice removal equipment.
