Function will not work
If a hydraulic function is dead but the pump and controls work, the solenoid valve or its coil is the usual suspect.
Drift or creep
A valve that does not seal lets cylinders creep. A new valve restores holding.
Burned coil
A coil that reads open or short on a meter needs replacing; check the connector for water first.
Fleet spares
Keep the common valves for your machines in stock to cut downtime.

Yes, it was made for the Komatsu PC60-6, and 4 more listed under compatible equipment. Check the old solenoid valve is marked 203-60-62161 or one of the cross references, because makers change parts between serial ranges.
On the Komatsu PC60-6, there is no fixed interval. It is changed when it fails, and many fail from water in the plug or chafed wiring rather than wear.
A fault code for this circuit, readings that jump or stay fixed, or a part that does not respond with power at the plug.
Read the fault codes, then check the plug and wiring for corrosion or a broken wire. A wiring fault reads the same as a failed solenoid valve.
Measure the coil resistance with a multimeter and check for supply voltage at the plug with the circuit on. An open coil reads infinite.
No. It is an aftermarket solenoid valve made to replace the Komatsu 203-60-62161. It is not made by the original manufacturer; the number only shows what it replaces.
