The Chelsea 489DLMBX-V6RK is an 8-bolt Power Take-Off unit from the Chelsea 489 Series, designed to bolt directly to an 8-bolt transmission opening on most manual transmissions including Eaton Fuller, Mack, and Tremec. The one-piece cast iron housing eliminates the need for an adapter plate, cutting installation time and reducing potential leak paths. The 489 Series delivers intermittent torque of 201-300 lb-ft and shaft output of 24 HP at 500 RPM or 48 HP at 1,000 RPM. Shift type is wire/cable mechanical. The output shaft is a 1-1/4" round shaft with key. Internal parts are common to the Chelsea 442 Series, keeping service familiar for technicians already working with that platform. A genuine Chelsea part, available from Pro Gear and Transmission.
