Kobelco excavator pump control using the matching 107 valve model
Confirm 12v, connector, flange mounted kawasaki cartridge, seals and hydraulic circuit before installation.
| Quantity: | |
|---|---|
KDRDE5K-31/30C50-107-T is a 12V hydraulic pump solenoid valve for Kobelco excavator pump control using the matching 107 valve model. Buyers should confirm the complete old marking, electrical version, connector, flange mounted kawasaki cartridge and hydraulic function before approving replacement stock.

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-31/30C50-107 / YB35V00005F1 |
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 pump control using the matching 107 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 dealer parts counter checks an old sample, keep the verified reference, measurements and test result in the service record. Approve KDRDE5K-31/30C50-107-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 an electrical voltage drop is found, 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 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 pilot passage blockage is investigated, keep the verified reference, measurements and test result in the service record. Reuse is not recommended when the service procedure specifies new seals or the old rings show flattening, cuts or heat damage. Confirm material compatibility with the hydraulic oil, clean the flange mounted kawasaki cartridge and inspect the manifold bore for scoring. Lubricate and install seals without twisting, then follow the equipment torque procedure instead of forcing the cartridge past resistance.
During a machine returns after long storage, 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-31/30C50-107 / YB35V00005F1 in purchasing records. Accept a cross reference only after dimensional, electrical and hydraulic checks agree.
During a valve switches slowly after oil warms, 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.
During a first article sample is reviewed, keep the verified reference, measurements and test result in the service record. Keep ports capped, seals protected and connector faces free from moisture or impact. Separate 12v and suffix variants with readable carton labels so warehouse picking cannot mix them. Store the valves in a clean, dry area away from welding dust and corrosive chemicals, and retain lot traceability to the approved sample and incoming inspection record.
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.
