The Chelsea 489 Series Power Take-Off Assembly, part number 489XRITX-V3GF or 489XRITXV3GF, mounts directly to the 8-bolt transmission opening on most manual transmissions including Eaton/Fuller and Volvo/Mack applications. The one-piece cast iron housing eliminates the need for an adapter plate, reducing potential leak paths. Wire/cable mechanical shift is standard for this configuration. The 1-1/4" round output shaft with key delivers up to 250 lb-ft intermittent torque, matching the torque capacity of the 442 Series. Shaft power rates at 24 HP at 500 RPM and 48 HP at 1,000 RPM. Call us to confirm proper fit for your specific transmission.
The Chelsea 489 Series is engineered for vocational and municipal applications including utility trucks, dump trucks, snow and ice removal equipment, and fire and rescue apparatus. Eleven internal speed ratios and multiple shift options make this a versatile PTO across a wide range of installations. The kit-style design simplifies field service, and internal parts shared with the 442 Series mean broad parts availability. Twenty-seven output options are available across the 489 Series, including a 360-degree rotatable flange with greaseable shaft to reduce pump shaft spline fretting and corrosion. Tapered bearings replace needle bearings for greater load-bearing capability.
