The Chelsea 489 Series Power Take-Off, part number 489XUAHX-A3XR or 489XUAHXA3XR, mounts directly to an 8-bolt transmission opening on most manual transmissions including Eaton Fuller, Volvo/Mack, and Tremec. The one-piece cast iron housing eliminates the adapter plate that a standard 6-bolt PTO requires, removing one potential leak path from the installation. Output is through a Chelsea Special (Cloverleaf) flange with a 7/8" 13-tooth SAE B shaft. Shift is air shift. The series delivers up to 250 lb-ft intermittent torque and draws 24 HP at 500 RPM or 48 HP at 1,000 RPM from the shaft. Tapered output bearings handle radial loads without needle-bearing limitations, and internal parts are common with the Chelsea 442 Series, simplifying bench work. Available for aerial, vocational, dump, utility, snow removal, and fire/rescue applications. Call us to confirm proper fit for your transmission.
