How to Change a Tractor’s Hydraulic Pump

30

Hydraulic systems function by transferring force applied at one end of the system through the compression of an oil-based fluid. The system’s hydraulic pump functions by using the weight of a lager amount of fluid to compress a smaller amount of fluid through a hose to operate pistons that operate an apparatus such as a tractor’s plow or tiller. Over time the bearing and seals in the hydraulic pump will wear out, requiring you to change the tractor’s hydraulic pump.

Step 1

Lower all hydraulic powered accessories to the ground, using their control levers. Disconnect the tractor’s negative battery cable with a wrench.

Step 2

Place the drain pan under the hydraulic fluid reservoir and remove the drain plug from the reservoir with a socket wrench. Replace the drain plug after the fluid has drained. Move the drain pan under the hydraulic pump. Open the bleeder valve on the hydraulic pump with a wrench to relieve any pressure in the pump.
