The Chelsea 489 Series Power Take-Off, part number 489XRAHX-V3RK or 489XRAHXV3RK, is an 8-bolt mechanical shift PTO designed for 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. The series delivers intermittent torque in the 201-300 lb-ft range and output power of 46-55 HP. Strong tapered bearings replace needle bearings for greater load-bearing capability. The 489 Series carries 27 output options and 11 internal speed ratios, making it a versatile choice for utility trucks, dump trucks, snow and ice removal, and fire and rescue applications.
