The Chelsea 878XEFJP-M5XV or 878XEFJPM5XV is a constant mesh Power Take-Off from the Chelsea 878 Series, designed to fit Allison and CAT 10-bolt transmissions. The 878 Series delivers up to 670 lb-ft of continuous duty torque, the highest torque capability in its class. A ductile iron bearing cap rated 117% stronger than gray iron, an o-ring sealing configuration between the housing and bearing cap, and rotatable cast-iron flanges set this unit apart from its predecessor. Nine speed ratios cover low and high speed demands across snow and ice, vacuum, aerial, and refuse truck applications. A Wet Spline Lubrication option extends shaft life 7 to 10 times over standard configurations. Call us to confirm proper fit for your application.
The Chelsea 878 Series is an evolution of the proven 877 Series platform, engineered to handle the increased vibration loads produced by modern and future engine designs. Steel disc thickness within the clutch pack has been increased by 80% compared to the earlier series. Markets served include snow and ice, vacuum, aerial, and refuse truck applications. The 878 Series parts list is published as Parker document HY25-2871-M1/US; the series owner's manual covers the 267, 281, 288, 871, and 878 Series. Part number 878XEFJP-M5XV is also referenced as SP878XEFJP-M5XV.
