The Chelsea 489GRAHX-A3XD or 489GRAHXA3XD is an 8-bolt Power Take-Off assembly from the 489 Series, designed for manual transmissions including Eaton/Fuller and Volvo/Mack applications. It uses wire/cable mechanical shifting and accepts a 1-1/4" round output shaft with an optional keyed configuration. Intermittent torque capacity falls in the 250 lb-ft (339 Nm) range, with shaft power output of 24 HP at 500 RPM and 48 HP at 1,000 RPM. The integral 8-bolt housing eliminates the need for an adapter plate, reducing potential leak paths. Internal components share commonality with the Chelsea 442 Series, simplifying parts sourcing and service. Cross-references include S-10752 and 2000XJA011SE.
