Komatsu PC200-8 Hydraulic Parts Buying Guide
A practical sourcing guide for PC200-8 hydraulic pumps, control valves, motors, cylinders and seal kits.
Quick answer
For Komatsu PC200-8 hydraulic parts, use the complete machine model and serial number together with the component nameplate, old part number and configuration photos. Pumps, valves and motors can vary by specification, and cylinder seal kits must be matched to the exact cylinder position and dimensions or reference.
Hydraulic pump identification
Photograph the complete pump nameplate and every side of the installed or removed pump. The regulator, control solenoids, shaft, mounting flange and port layout are important configuration evidence.
State whether you need a complete pump, main-pump assembly, regulator, solenoid or internal repair parts. Do not compare a bare pump quotation with a complete configured assembly.
- Full pump model code
- PC200-8 machine serial number
- Regulator and solenoid arrangement
- Shaft, flange and hydraulic ports
- Complete assembly or repair-parts scope
Control valve and valve-related parts
A main control valve request should include the valve label, full body photos, port side, installed orientation and the affected machine function. Individual valve sections, spools and seals require more exact internal identification.
If a fault is limited to boom, arm, bucket, swing or travel, include that symptom. Diagnosis should be completed before ordering a full valve because pilot, electrical and actuator faults can create similar behavior.
- Valve plate or casting references
- Overall body and port-side photos
- Affected function and test results
- Requested complete valve or component
Swing motor, travel motor and final drive
For swing and travel components, clarify whether the request is for a hydraulic motor, reduction gearbox or complete device. Send all labels and mounting-interface photos.
Weak or abnormal movement is not proof that the motor itself is damaged. Record pressure-test information and inspect gearbox oil or drained hydraulic oil when appropriate.
- Motor and gearbox labels
- Mounting bolt pattern and ports
- Brake and control arrangement
- Failure symptom and contamination evidence
Cylinders and seal kits
Identify whether the cylinder is for boom, arm or bucket. Send the cylinder assembly number when readable, plus machine serial number and photos of the gland, ports and mounting ends.
For a seal kit without a readable number, rod diameter, bore diameter and seal-groove data may be needed. Measurements should be taken by a technician after safe dismantling.
- Cylinder position
- Cylinder or seal-kit number
- Rod and bore dimensions when required
- Old seals arranged and photographed after removal

Frequently asked questions
Are all PC200-8 hydraulic pumps interchangeable?
No. Configuration and serial-number differences must be checked using the pump code, machine data and interface photos.
Can I identify a seal kit from the excavator model?
The cylinder position and exact cylinder reference or dimensions are normally needed.
Why does the supplier ask for regulator photos?
Similar pump models can use different control configurations. Regulator and solenoid photos help confirm the supplied assembly.
