The Chelsea 489 Series Power Take-Off Assembly, part number 489GRAHX-A3GK or 489GRAHXA3GK, is an 8-bolt PTO built for most manual transmissions including Eaton/Fuller, Volvo/Mack, and Tremec. The one-piece cast iron housing bolts directly to the 8-bolt transmission opening, eliminating the adapter plate and reducing potential leak paths. Shift type is wire/cable mechanical. Output shaft is a 1-1/4" round shaft with key. The 489 Series delivers intermittent torque in the 201-300 lb-ft range and shaft power of 24 HP at 500 RPM and 48 HP at 1,000 RPM. Internal parts are common to the Chelsea 442 Series. Typical applications include utility trucks, dump trucks, snow and ice removal equipment, and fire and rescue vehicles.
