The Chelsea 489 Series Power Take-Off Assembly, part number 489XFAHX-V3XY or 489XFAHXV3XY, is a wire/cable mechanical shift PTO built on an 8-bolt mounting pattern that bolts directly to the transmission opening without an adapter plate, eliminating an extra potential leak path. The one-piece cast iron housing delivers the same 250 lb-ft intermittent torque rating as the 442 Series, supported by tapered bearings rather than needle bearings for greater load capacity. Output power runs 46-55 HP, with shaft power of 24 HP at 500 RPM and 48 HP at 1,000 RPM. The 1-1/4" round output shaft with key suits a wide range of driven equipment. Compatible transmission families include Eaton/Fuller, Volvo/Mack, and others with an 8-bolt PTO aperture. Available in no-pressure-lube (X) or pressure-lube (P) configurations. Call us to confirm proper fit for your specific transmission and application.

The Chelsea 489 Series fits a broad range of vocational truck applications including utility trucks, dump trucks and trailers, snow and ice removal equipment, and fire and rescue vehicles. Eleven internal speed ratios and 27 output options, including a 360-degree rotatable flange with greaseable shaft, make this a versatile PTO for aerial, municipal, and other mobile equipment. Internal components are common to the Chelsea 442 Series, simplifying parts inventory for shops already familiar with that platform.
