The Chelsea 288GCFJP-M5RY or 288GCFJPM5RY is a 10-bolt, constant mesh Power Take-Off built on the 288 Series platform. This heavy-duty PTO delivers a single, continuous duty torque rating of up to 390 lb-ft, made possible by wider gears and larger-capacity bearings compared to earlier Chelsea designs. The cast iron housing keeps costs practical for fleet applications, while ductile iron bearing caps bring 117% greater strength than gray iron. An O-ring sealing configuration between the housing and bearing cap improves clamp load and reduces the vibrational effects of modern engine designs. The standard output shaft includes a positive stop feature to protect the oil seal from driveline couplings. Nine speed ratios cover both low and high speed requirements. Call us to confirm proper fit for your transmission application.
The 288 Series is suited for demanding vocational markets including snow and ice control, vacuum trucks, aerial equipment, and refuse vehicles. The 288 Series supersedes the Chelsea 287 Series and incorporates engineering upgrades specifically aimed at durability under the vibrational demands of modern engine designs. Wet Spline technology delivers a continuous flow of clean oil through the PTO and pump shaft, preventing 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.
