The Chelsea 489 Series Power Take-Off Assembly, part number 489GFAHX-V3XY or 489GFAHXV3XY, is a wire/cable mechanical shift PTO built for 8-bolt manual transmission openings. The one-piece cast iron housing mounts directly to the transmission without an adapter plate, which removes a potential leak path compared to bolted-on adapter designs. The 489 Series delivers the same intermittent torque rating as the Chelsea 442 Series and uses common internal parts, so shop stock and service procedures carry over. Output runs through a 1-1/4" round shaft with keyway. Shaft power rates at 24 HP at 500 RPM and 48 HP at 1,000 RPM. Compatible transmission manufacturers include Eaton/Fuller, Volvo/Mack, and others with an 8-bolt PTO aperture. Call us to confirm proper fit for your specific transmission and application.
