Frequently Asked Questions & Maintenance Tips

Understanding Common Hydraulic Spare Parts (Komatsu & Caterpillar)

To further assist you in identifying hydraulic components, here are definitions for 10 common Komatsu and Caterpillar hydraulic spare parts, along with their typical locations and examples:

• Main Control Valve: Located in the hydraulic system's center, it directs fluid flow to various cylinders and motors. Example: Komatsu PC200-8 Main Control Valve.

• Swing Motor: Mounted on the excavator's frame, powers the rotation of the upper structure. Example: CAT 320D Swing Motor.

• Travel Motor: Located at the tracks (or wheels), drives the machine's movement. Example: Komatsu D65PX-15 Travel Motor.

• Boom Cylinder Seal Kit: Internal seals located within the boom cylinder to prevent hydraulic fluid leakage. Example: CAT 336E Boom Cylinder Seal Kit.

• Pilot Valve (Control Valve): Often located near the operator controls, sends pilot pressure signals to control the main control valve spools. Example: Komatsu WA380-6 Pilot Valve.

• Charge Pump: A small pump often mounted on the main hydraulic pump, supplies oil to the main pump inlet or specific system circuits. Example: CAT 950H Charge Pump.

• Relief Valve: Typically located within the main control valve or pump, it limits maximum system pressure by diverting excess fluid. Example: Komatsu PC300-7 Relief Valve.

• Hydraulic Filter Element: Housed in the hydraulic tank or lines, removes contaminants from the hydraulic fluid. Example: CAT D8T Hydraulic Filter Element.

• Bucket Cylinder: A hydraulic cylinder attached to the boom and bucket, used to curl and dump the bucket. Example: Komatsu PC450-8 Bucket Cylinder.

• Swivel Joint (Center Joint): Located under the center of the machine, allows hydraulic fluid to pass between the rotating upper structure and the stationary lower structure. Example: CAT 320D Swivel Joint.
