The Chelsea 880 Series Power Take-Off, part number 880XBAKP-Y5XV or 880XBAKPY5XV, is a heavy-duty 8-bolt PTO built for high-torque, demanding service. It delivers up to 500 lb-ft (678 Nm) intermittent torque and is rated for continuous operation with a 30% de-rating. Output is through a 1-1/2"-10 spline shaft with a 1410 companion flange. Shaft power reaches 48 HP at 500 RPM and 95 HP at 1000 RPM. The lever mechanical shift uses constant mesh input gears and a removable shift cover that simplifies backlash adjustment. Compatible with Volvo/Mack, Allison, Eaton/Fuller, and other transmissions with an 8-bolt aperture. Typical applications include fire trucks, bulk haulers, oil field equipment, large tow and recovery trucks, and aerial units. Call us to confirm proper fit for your transmission.
