The Chelsea 880DMMAX-V6XK or 880DMMAXV6XK is an 8-bolt, lever mechanical-shift power take-off assembly built for heavy-duty applications including bulk haulers, fire trucks, oil field equipment, aerial units, and large recovery trucks. It delivers up to 500 lb-ft intermittent torque (check application pages for confirmed ratings) and is rated for 48 HP at 500 RPM and 95 HP at 1,000 RPM. The output shaft is a 1-1/2"-10T spline with a 1410 companion flange, and the dual-pump design allows a hydraulic pump to be mounted on each end of the unit. Continuous operation is supported with a 30% de-rating. The cast iron housing and removable shift cover, which simplifies backlash adjustment, make this unit suited for demanding on-highway and off-highway service.
