The Chelsea 880QMMEX-D4GS or 880QMMEXD4GS is an 880 Series power take-off assembly built for heavy-duty hydraulic applications. It mounts via an 8-bolt pattern and engages through a lever mechanical shift. The output shaft is a 1-1/2"-10T spline with a 1410 companion flange, supporting dual-pump output so a hydraulic pump can be mounted on each end of the unit simultaneously. Intermittent torque capacity reaches 500 lb-ft (678 Nm); check Chelsea application pages for torque ratings specific to your installation. Shaft power is rated at 48 HP at 500 RPM and 95 HP at 1,000 RPM. Compatible transmission families include Volvo/Mack, Allison, and Eaton/Fuller. Cast iron housing with a simple backlash adjustment speeds installation. Call us to confirm proper fit for your transmission.
