The Chelsea 489 Series Power Take-Off Assembly, part number 489XRAHX-A3GY or 489XRAHXA3GY, mounts directly to 8-bolt transmission openings on most manual transmissions including Eaton Fuller, Mack, and Tremec without requiring an adapter plate. The one-piece cast iron housing reduces potential leak paths compared to adapter-plate designs. Shift type is wire/cable mechanical. The 1-1/4" round output shaft with keyway delivers up to 250 lb-ft intermittent torque and shaft power of 24 HP at 500 RPM and 48 HP at 1000 RPM. Internal parts are common to the Chelsea 442 Series. Applications include utility trucks, dump trucks, snow and ice removal equipment, and fire and rescue vehicles. Call us to confirm proper fit for your transmission.
