The Chelsea 489QQLZX-V3RY is an 8-bolt Power Take-Off unit from the Chelsea 489 Series, designed to bolt directly to the 8-bolt opening on most manual transmissions including Eaton Fuller, Mack, and Tremec. The integral 8-bolt cast iron housing eliminates the need for an adapter plate, reducing both installation time and potential leak paths. Shift type is wire/cable mechanical. 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. Tapered bearings replace needle bearings for greater load-bearing capability. Available from Pro Gear and Transmission.
