The Chelsea 489 Series Power Take-Off, part number 489GQAHX-A3GF or 489GQAHXA3GF, is a mechanical-shift PTO designed for manual transmissions with an 8-bolt mounting aperture, including Eaton Fuller, Mack, and Tremec units. The one-piece cast iron housing bolts directly to the 8-bolt opening, eliminating the need for an adapter plate and reducing potential leak paths compared to two-piece designs. The 489 Series uses tapered bearings rather than needle bearings for greater load capacity. Output is through a 1-1/4 inch round keyed shaft. Intermittent torque rating for the 489 Series runs 201 to 300 lb-ft, with shaft power of 24 HP at 500 RPM and 48 HP at 1,000 RPM. Pro Gear and Transmission carries this genuine Chelsea unit.
