The Chelsea 288GSFJP-M5XD or 288GSFJPM5XD is a 10-bolt, constant mesh power take-off from the Chelsea 288 Series, built on the 281 Series platform. The 288 Series delivers a single continuous duty torque rating of up to 390 lb-ft, with wider gears and larger-capacity bearings than the 287 Series it replaces. 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 the damaging vibrational effects of 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 needs. Wet Spline Lubrication is available as an option, providing 7 to 10 times greater shaft life. A hydraulic hose is included. Sold by Pro Gear and Transmission. Call us to confirm proper fit for your application.

The 288 Series is suited for demanding applications including snow and ice control, vacuum, aerial, and refuse trucks. Parker Chelsea 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. The cross-reference part number from supplier records is SP288GSFJP-M5XD.
