The Chelsea 489QRLZX-D3AZ is an 8-bolt Power Take-Off unit from the Chelsea 489 Series, designed for an Eaton Procision mount with an 8-bolt aperture. The one-piece cast iron housing eliminates the need for an adapter plate, reducing both installation time and potential leak paths. The 489 Series delivers intermittent torque in the 201-300 lb-ft range and shifts via 12V electric/air actuation. Output is through an SAE B 4-bolt flange with a 1-1/4" 14-tooth SAE C shaft. The 489 Series is rated at 24 HP at 500 RPM and 48 HP at 1,000 RPM. Tapered bearings replace needle bearings for greater load capacity. Available from Pro Gear and Transmission.
