The Chelsea 489 Series Power Take-Off, part number 489XCAHP-M4XQ or 489XCAHPM4XQ, is a mechanical-shift PTO built for manual transmissions with an 8-bolt mounting aperture. The integral 8-bolt cast iron housing bolts directly to the transmission opening without an adapter plate, eliminating a potential leak path. The 489 Series delivers intermittent torque in the 201-300 lb-ft range and output power of 46-55 HP, with shift via wire or cable. Output is through a 1-1/4" round shaft with key. Tapered bearings replace needle bearings for greater load capacity. Compatible transmissions include Eaton Fuller, Eaton Endurant, Mack, and Tremec. Call us to confirm proper fit for your specific transmission and application.
