Understanding Hydraulic Components: Key Terms

Familiarizing yourself with the different hydraulic components on your machine is essential for maintenance and troubleshooting. Here are definitions for 10 additional hydraulic parts found in construction machinery (distinct from the products listed above):

• Main Control Valve: Manages and directs hydraulic fluid flow to various actuators (cylinders, motors) based on operator input. Found in the hydraulic system's control circuit. Example: Komatsu PC200-7 Main Control Valve.

• Swing Motor: A hydraulic motor that provides the rotational power for the excavator's upper structure (cab and boom) to swing. Located in the swing drive assembly. Example: Caterpillar CAT 320D Swing Motor.

• Steering Cylinder: A hydraulic cylinder used to articulate or steer wheel loaders or other articulated vehicles. Typically located in the machine's articulation joint. Example: Komatsu WA470-3 Steering Cylinder.

• Ripper Cylinder: A hydraulic cylinder that raises, lowers, and applies downforce to the ripper attachment on bulldozers. Located on the rear of the bulldozer frame. Example: Caterpillar CAT D8T Ripper Cylinder.

• Travel Motor: A hydraulic motor that drives the tracks (excavators, bulldozers) or wheels (some loaders). Located at the final drive or wheel hub. Example: Komatsu PC300-8 Travel Motor.

• Blade Lift Cylinder: Hydraulic cylinders used to raise and lower the blade on motor graders or bulldozers. Located between the frame and the blade assembly. Example: Caterpillar CAT 140H Blade Lift Cylinder.

• Tandem Pump: Two hydraulic pumps mounted together and driven by a single shaft, often used to power different circuits (e.g., steering and implements) simultaneously. Located near the engine/power takeoff. Example: Komatsu GD655-5 Tandem Pump.

• Bucket Cylinder: A hydraulic cylinder that controls the tilting and dumping action of a loader or excavator bucket. Located connecting the boom/stick to the bucket. Example: Caterpillar CAT 966M Bucket Cylinder.

• Brake Valve: A hydraulic valve that controls the hydraulic pressure applied to engage or release the brakes, often found in wheel loaders or haul trucks. Located within the hydraulic braking circuit. Example: Komatsu HM400-2 Brake Valve.

• Screed Cylinder: Hydraulic cylinders that adjust the width, height, or slope of the screed on asphalt pavers. Located on the screed unit. Example: Caterpillar CAT AP655F Paving Screed Cylinder.
