489GQAHX-V3AZ Chelsea 489 Series PTO

The Chelsea 489 Series Power Take-Off, part number 489GQAHX-V3AZ or 489GQAHXV3AZ, is a mechanical-shift PTO designed for manual transmissions with an 8-bolt PTO mounting aperture, including Eaton Fuller, Mack, and Tremec gearboxes. The one-piece cast iron housing bolts directly to the 8-bolt opening, eliminating the need for a separate adapter plate and reducing potential leak paths. The 489 Series delivers intermittent torque in the 201-300 lb-ft range and output power of 46-55 HP. Strong tapered bearings replace needle bearings for greater load-bearing capability. Output is through a 1-1/4" round keyed shaft. Call us to confirm proper fit for your transmission and application.

Additional Information

Tapered bearings are used throughout in place of needle bearings, increasing load-bearing capacity. The series offers twenty-seven output options, including Chelsea's 360-degree rotatable flange with a greaseable shaft to reduce spline fretting and corrosion. Eleven internal speed ratios and shift configurations are available across the 489 Series line, making it adaptable to utility trucks, dump trucks, snow and ice removal equipment, fire and rescue vehicles, and aerial equipment.
