The one-piece cast iron housing mounts directly to the transmission opening without an adapter plate, reducing potential leak paths. Output is through a 1-1/4" round shaft with keyway. Shift is wire/cable mechanical. The 489 Series carries an intermittent torque rating of 201-300 lb-ft (301-400 Nm) and delivers up to 48 HP at 1,000 RPM. Internal parts are common to the Chelsea 442 Series, and the kit-style design simplifies service. A genuine Chelsea part sold by Pro Gear and Transmission.
