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-31/30C40-111 / YB35V00003F1 |
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 Kawasaki valve 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 a repeat coil heating case is investigated, keep the verified reference, measurements and test result in the service record. Approve KDRDE5K-31/30C40-111-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 distributor separates similar suffix variants, keep the verified reference, measurements and test result in the service record. Read the coil label first and measure voltage at the connector while the real machine command is active. The working reference for this page is 12V. Do not infer voltage only from battery count because converters, harness changes and mixed voltage fleets can create misleading assumptions. Record the verified value on the purchase order and incoming inspection label.
During a dealer parts counter checks an old sample, keep the verified reference, measurements and test result in the service record. Use the drawing to compare overall length, thread or flange position, sealing diameters and connector clearance with the removed component. Read the spring side of the hydraulic symbol as the normal state and the solenoid side as the energized state. Port letters are catalog identifiers and must be reconciled with the equipment schematic before commissioning.
During an electrical voltage drop is found, 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 export packing is approved, 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 dealer parts counter checks an old sample, keep the verified reference, measurements and test result in the service record. Treat every suffix as an engineering identifier until its meaning is proven. A suffix can change voltage, connector, spring calibration, spool geometry or mounting details while the base model remains similar. Keep the complete old marking on the quotation and do not shorten KDRDE5K-31/30C40-111 / YB35V00003F1 in purchasing records. Accept a cross reference only after dimensional, electrical and hydraulic checks agree.
During an electrical voltage drop is found, keep the verified reference, measurements and test result in the service record. The spring side of the circuit symbol defines what the machine does when electrical power is absent. That state can hold, unload, block or route pilot pressure, and the wrong choice may create movement or pump load at startup. Compare the original schematic with the catalog symbol and verify the safe normal condition before energizing the replacement in the machine.
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.
