The Chelsea 489 Series Power Take-Off, part number 489GHAHX-V3GY or 489GHAHXV3GY, is a mechanical-shift PTO built on an 8-bolt mounting pattern that fits most manual transmissions including Eaton Fuller, Mack, and Tremec. The one-piece cast iron housing bolts directly to the 8-bolt transmission opening, eliminating the need for an adapter plate and reducing potential leak paths. The 489 Series delivers intermittent torque in the 201-300 lb-ft range and output power from 46 to 55 HP. Output is through a 1-1/4 inch round keyed shaft. Tapered bearings replace needle bearings for greater load capacity. Available through Pro Gear and Transmission. Call us to confirm proper fit for your application.

Additional Information
The Chelsea 489 Series shares internal parts with the 442 Series, giving the same 250 lb-ft torque capacity in a direct-mount 8-bolt housing. The series offers twenty-seven output options, including Chelsea's 360-degree rotatable flange with a greaseable shaft to reduce pump shaft spline fretting and corrosion. Eleven internal speed ratios and shift configurations make it adaptable across a wide range of vocational applications including utility trucks, dump trucks, aerial equipment, and snow and ice removal.
