The Chelsea 489GFAHX-A5RY or 489GFAHXA5RY is a 489 Series Power Take-Off (PTO) designed for manual transmissions with an 8-bolt PTO mounting aperture. The one-piece cast iron housing bolts directly to the transmission opening, eliminating the need for an adapter plate and reducing potential leak points. This series delivers intermittent torque in the 201-300 lb-ft range and output power from 46 to 55 HP, with shaft power rated at 24 HP at 500 RPM and 48 HP at 1000 RPM. Shift type is wire/cable mechanical. The output shaft is a 1-1/4 inch round shaft with key. Strong tapered bearings replace needle bearings for greater load-bearing capability. 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.
