The Chelsea 288 Series Power Take-Off Assembly, part number 288GKFJP-M5RK or 288GKFJPM5RK, is a heavy-duty 10-bolt constant mesh PTO built on the proven 281 Series platform. It delivers a single continuous duty torque rating and features ductile iron bearing caps rated 117% stronger than gray iron. An O-ring sealing configuration between the housing and bearing cap reduces vibrational effects and improves clamp load. The standard output shaft is a 1-inch round shaft with a 1/4-inch key and includes positive stop to prevent oil seal damage at driveline couplings. Nine speed ratios cover both low and high range, and the Wet Spline Lubrication option extends pump shaft life by 7 to 10 times. Cast iron housing with rotatable flanges reduces interference clearance issues. The hose is included, so no separate order is needed. Typical markets include snow and ice, vacuum, aerial, and refuse applications. Call us to confirm proper fit for your specific transmission and application.
