The Chelsea 880XBAKX-Y4XS or 880XBAKXY4XS is an 880 Series heavy-duty power take-off assembly built for 8-bolt manual transmission apertures. It uses lever mechanical shift and delivers up to 500 lb-ft (678 Nm) intermittent torque, with shaft power rated at 48 HP at 500 RPM and 95 HP at 1000 RPM. The output shaft is a 1-1/2"-10T spline fitted with a 1410 companion flange. Cast iron housing with tapered cone bearings handles high-torque, continuous-duty service (continuous operation with 30% de-rating). A removable shift cover makes backlash adjustment straightforward. Common applications in the 880 Series include bulk haulers, fire trucks, large tow and recovery trucks, oil field equipment, and aerial units.
