489XFAHX-P5AF Chelsea 489 Series PTO

The Chelsea 489 Series Power Take-Off, part number 489XFAHX-P5AF or 489XFAHXP5AF, is a 12V electric/air shift PTO designed for manual transmissions with an 8-bolt mounting aperture, including Eaton Fuller, Mack, and Tremec gearboxes. 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. This 489 Series unit features strong tapered bearings rather than needle bearings for greater load-bearing capability. The series delivers intermittent torque in the 201-300 lb-ft range and output power of 46-55 HP. The output is an SAE B 2 or 4-bolt flange with a 1" 15-tooth SAE BB shaft, and shift is accomplished via 12V electric/air shift actuation. Internal parts are common to the Chelsea 442 Series, making service straightforward. Call us to confirm proper fit for your application.
