The Chelsea 489 Series Power Take-Off Assembly, part number 489GRAHX-V3GA or 489GRAHXV3GA, mounts directly to an 8-bolt transmission opening using a one-piece cast iron housing that eliminates the need for an adapter plate and reduces potential leak paths. The series delivers intermittent torque in the 201-300 lb-ft range and shaft power of 24 HP at 500 RPM or 48 HP at 1000 RPM. Shift is wire/cable mechanical, and the output shaft is a 1-1/4" round with key. Compatible transmissions include Eaton Fuller, Mack, and Tremec. Tapered bearings replace needle bearings for greater load capacity. Internal parts are common to the Chelsea 442 Series, simplifying service.
