138-0529 Gear Motor

The 138-0529 is a hydraulic gear pump responsible for delivering hydraulic fluid in heavy equipment hydraulic systems to achieve smooth flow and pressure. It is typically classified as an auxiliary pump or a hydraulic fan drive pump.

Key Features

• Fixed Displacement: The pump is a fixed-displacement type, meaning it delivers a constant flow of hydraulic fluid per revolution of the gears.

• Durable Construction: It features a robust two-piece cast-iron housing design, which is more durable than three-piece aluminum alternatives and helps prevent shaft seal leaks that may result from impact or harsh operating conditions.

• High Contamination Resistance: Due to its relatively simple design, the gear pump offers higher resistance to fluid contamination compared to more complex pump types like piston pumps.

• Consistent Flow and Pressure: It uses meshing gears to enable steady flow and pressure for consistent equipment operation in systems like the hydraulic fan drive or implement circuits.

• Optimized Components: Features rugged journal bearings, high-pressure end plates, and high-temperature seals that are specifically designed to extend component life and improve durability.

• Cost-Effectiveness: The lower complexity contributes to a lower purchase cost and easier maintenance, which can result in reduced overall ownership costs.

Application

• Caterpillar 980G Wheel-Type Loader: This is the main piece of equipment the 138-0529 pump is designed for.

• Implement System: It supplies the pressurized hydraulic fluid necessary to operate the loader's implements, such as lifting, tilting, and controlling the bucket.

• Hydraulic Fan Drive: It is also used to power the hydraulic cooling fan, regulating engine temperature by moving air through the radiator and coolers.

• Compatible Engines

• The pump is compatible with Caterpillar engines commonly found in the 980G loader:
