Designed for Allison transmissions with cooler or retarder options, the Chelsea 877-XL Series PowerShift PTO allows direct mounted pumps to be moved further rearward in the truck chassis.
Extended shaft PTOs fit neatly between the transmission and frame rail of the truck and locates the pump rear of the transmission where it’s common for space to be available. The 877-XL retains the same robust qualities (a continuous rating of up to 670 lbs-ft) of its 877 Series sibling including high capacity bearings and superior gear designs. Versatitlity, power, ease of maintenance and installation make the 877 Series the best choice for Snow & Ice, Refuse, Aerial, and Defense truck requirements.
