The Chelsea 489 Series Power Take-Off, part number 489XLAHX-A3GY or 489XLAHXA3GY, is a mechanical shift PTO designed for manual transmissions with an 8-bolt mounting aperture, including Eaton Fuller, Mack, and Tremec. The integral 8-bolt cast iron housing bolts directly to the transmission opening without an adapter plate, reducing potential leak paths and cutting installation time. Shift is wire/cable mechanical type. The series delivers intermittent torque in the 201-300 lb-ft range and shaft power of 24 HP at 500 RPM or 48 HP at 1,000 RPM. Output is via a 1-1/4 inch round keyed shaft. Tapered bearings provide greater load capacity than needle-bearing designs. Call us to confirm proper fit for your specific transmission.
