The Chelsea 288 Series Power Take-Off, part number 288GKFJP-M5RF or 288GKFJPM5RF, is a heavy-duty 10-bolt constant mesh PTO built on the proven 281 Series platform. Wider gears and larger-capacity bearings support a single continuous duty torque rating of up to 390 lb-ft. Ductile iron bearing caps are 117% stronger than gray iron, and an O-ring sealing configuration between the housing and bearing cap improves clamp load while reducing vibration damage from modern engine designs. The standard output shaft features a positive stop for driveline outputs, eliminating oil seal damage from shaft couplings. Nine speed ratios cover both low and high speed applications. A hydraulic hose is included. Call us to confirm proper fit for your application.

The 288 Series replaces the Chelsea 287 Series PTO. Typical market applications include snow and ice control, vacuum, aerial, and refuse equipment. Parker documents covering this series include the 281/288 Series Parts List (HY25-2281-M1/US) and the 267/281/288/871/878 Series Owner's Manual.
