Additional Information
Parts Manual: Chelsea 288 Series PTO Parts Manual (PDF), exploded views, item numbers and the full parts breakdown for this series.
The 288 Series is suited for demanding applications including snow and ice control, vacuum, aerial, and refuse trucks. It directly replaces the Chelsea 287 Series PTO. The Wet Spline Lubrication option, when specified, routes a continuous flow of clean oil through the PTO and pump shaft to prevent premature spline fretting. Parker/Chelsea reference documents for this series include the 281/288 Series Parts List (HY25-2281-M1/US) and the 267/281/288/871/878 Series Owner's Manual.
