203-60-56180 Swing Solenoid Valve for Komatsu PC60-6

The 203-60-56180 swing solenoid valve is supplied for Komatsu excavator hydraulic control system repair. It is commonly searched as 203-60-56180, 2036056180, 203-60-56560, 2036056560, SD1169-24-11, SD11692411, Komatsu PC60-6 solenoid valve, PC60-5 solenoid valve, PC120-5 solenoid valve, old type solenoid valve, swing solenoid valve or rotary solenoid valve for Komatsu excavator repair.

This page focuses on 203-60-56180 as the main part number. Ref cross numbers include 203-60-56560, 2036056560, SD1169-24-11 and SD11692411. Final fitment should be confirmed by the old valve number, connector type, voltage, plug shape, valve body structure, mounting position and machine information before ordering.

Machine and System Reference

Common machine references for this solenoid valve include Komatsu PC60-5, PC60-6, PC60-7, PC100-5, PC120-5 and PC130-5 excavators. Common engine references may include Komatsu 4D95 and 6D95 depending on machine configuration.

This part is commonly described as a swing solenoid valve, rotary solenoid valve or old type Komatsu solenoid valve. It works in the excavator hydraulic control system to help control the related swing or rotary hydraulic function through electrical activation.

Machine model alone is not enough for final confirmation. Komatsu PC-series excavators may use different solenoid valves depending on hydraulic circuit, engine arrangement, production configuration, serial range and repair history. The removed valve and old part number are more reliable than the machine model alone.

Part Number and Ref Cross Notes

203-60-56180 is the main identifying number of this product page. 2036056180 is the no-hyphen writing format and can be kept for search matching.

Ref cross numbers include 203-60-56560, 2036056560, SD1169-24-11 and SD11692411. These numbers are included because they are commonly listed together for this Komatsu old type swing solenoid valve direction.

Do not mix unrelated Komatsu solenoid valve numbers into this page unless the physical structure is confirmed. Similar solenoid valves may differ by connector shape, coil voltage, valve body length, port structure, mounting position and hydraulic circuit function.

How to Confirm the Correct Solenoid Valve

Before ordering 203-60-56180, compare the removed solenoid valve carefully. Small differences in connector, voltage, valve body and installation position may affect installation or machine operation.

• Confirm whether the old part number is 203-60-56180, 203-60-56560 or SD1169-24-11.

• Check whether the machine reference is Komatsu PC60-5, PC60-6, PC60-7, PC100-5, PC120-5 or PC130-5.

• Compare the connector type, plug shape and wiring position.

• Confirm the valve voltage before installation.

• Check the valve body, mounting holes, hydraulic ports and installation position.

• Send photos of the old valve number, connector, valve body, mounting area and machine nameplate before quotation if you are not sure.

Common Solenoid Valve Failure Symptoms

A swing solenoid valve may need replacement when the excavator has abnormal swing response, slow swing action, intermittent hydraulic operation, function failure, unstable hydraulic control, warning codes or no response from the related hydraulic circuit.

Before replacing the valve, check the wiring harness, connector pins, voltage supply, grounding, hydraulic oil condition and controller signal. Some problems may be caused by electrical faults, contamination or wiring damage rather than the solenoid valve alone.

If the old valve failed because of oil contamination, water ingress, poor connector contact or unstable voltage, the root cause should be repaired before installing the replacement valve. Otherwise, the new solenoid valve may fail early.

Installation and Testing Notes

Before installation, turn off the machine, release system pressure according to service requirements and clean the area around the valve. Make sure no dirt enters the hydraulic circuit during replacement.

After installation, connect the plug securely and check whether the related hydraulic function responds normally. Inspect for oil leakage, abnormal noise, warning codes or unstable operation during testing.

If the machine still has abnormal response after replacement, stop testing and recheck the old part number, connector, wiring harness, controller signal, hydraulic pressure and oil contamination before further operation.

Buying Notes for Repair Shops and Parts Distributors

For repair shops, this 203-60-56180 swing solenoid valve is suitable for Komatsu PC-series excavator hydraulic control repair when the old valve is damaged, stuck, electrically failed or unable to control the related hydraulic function correctly.

For parts distributors, it can be supplied as a Komatsu PC60-5, PC60-6, PC60-7, PC100-5, PC120-5 and PC130-5 solenoid valve reference for heavy equipment repair demand. Topvelsun supports small repair orders and bulk inquiries. Please send the required quantity, old valve number, machine model and photos of the old valve from multiple angles.
