Use the original catalog dimensional reference and hydraulic symbol to compare the valve with the removed component and the machine schematic before purchase approval.
Complete every control point below before a sample or bulk order is released.
Approval Point | Buyer Review |
|---|---|
Reference | KDRDE5K-20/30C12A-101 / YN35V00004F2 |
Electrical | 12V; verify at the loaded connector during the actual command |
Mechanical | Compare flange mounted kawasaki cartridge, cartridge length, seals and installed clearance |
Hydraulic | Confirm normal state, energized state and manifold port relationship |
Machine Evidence | Kobelco excavator hydraulic pump control using the exact C12A-101 model |
Separate electrical command, cartridge movement and machine response so the actual wiring or hydraulic fault is not hidden by a parts replacement.
Observed Condition | Recommended Check |
|---|---|
No movement | Check loaded connector voltage, ground, controller command and coil resistance. |
Slow response | Inspect oil cleanliness, filter condition, viscosity and cartridge movement. |
Reversed response | Stop operation and compare normal and energized port logic with the original valve. |
External leakage | Inspect seals, cartridge surface, manifold bore and correct seating depth. |
Repeated heating | Confirm voltage, duty cycle, connector resistance and full magnetic movement. |
During fleet stock is replenished for planned service, keep the verified reference, measurements and test result in the service record. Approve KDRDE5K-20/30C12A-101-T from the complete old valve marking, 12v electrical version, connector keying, flange mounted kawasaki cartridge, sealing lands and normal hydraulic state. A shared equipment model does not prove interchangeability because pump and manifold revisions can change during production. Send the machine model, serial number and clear removed part photos with the inquiry.
During a customer reports reversed machine response, keep the verified reference, measurements and test result in the service record. The 41 bar figure is a catalog or verified product reference, not permission to ignore the equipment hydraulic schematic. Confirm which ports see pressure in both de-energized and energized states, review return line conditions and follow the machine service limits. Pressure capability does not correct a wrong spool function, cartridge depth or manifold port relationship.
During a connector harness revision is compared, keep the verified reference, measurements and test result in the service record. Measure supply and ground at the loaded connector, then check coil resistance and verify that the controller is actually issuing the command. If electrical input is correct, inspect oil cleanliness, filter condition, cartridge movement and manifold contamination. Separate electrical command from hydraulic response before replacing another valve, otherwise a harness or blocked pilot passage may be missed.
During a manifold bore shows possible wear, keep the verified reference, measurements and test result in the service record. Provide the complete old label, machine model and serial number, confirmed voltage, connector face photo, cartridge or flange measurements, hydraulic function, required quantity and destination. For mixed fleets, separate each electrical and suffix version on the inquiry. This evidence allows a sample approval plan and prevents similar looking hydraulic pump solenoid valve variants from being combined in one bulk order.
During cold start commissioning is completed, keep the verified reference, measurements and test result in the service record. Serial number evidence is essential whenever the same equipment family used more than one pump, manifold or electrical harness. Use it with the parts diagram rather than as a substitute for physical checks. If the old valve label is damaged, collect connector, mounting, cartridge and installed location photos so the application can be narrowed without guessing from the machine name alone.
During a workshop compares two connector orientations, keep the verified reference, measurements and test result in the service record. Compare the connector face, key position, pin count, latch direction and cable exit with the removed component. Also check whether suppression is built into the coil because this can affect controller diagnostics. Photograph the connector straight on beside a ruler and include the terminal condition in the RFQ, especially when several Kobelco harness revisions are used in the same fleet.
During a service kit is packed for remote repair, keep the verified reference, measurements and test result in the service record. Measure voltage across the coil while the controller commands the valve, then measure the positive and ground side drops separately. A static open circuit reading can look normal while a corroded terminal collapses under load. Compare the result with the confirmed 12v requirement and repair excessive resistance before judging the hydraulic pump solenoid valve itself as defective.
Send the complete old valve marking, confirmed voltage, machine model and serial number, connector photos, interface dimensions and required quantity for a fitment focused B2B quotation.
