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 | 116-3526 / 315-4412 / KWE5K-31/G24E30-704 |
Electrical | 24V; 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 | Caterpillar excavator hydraulic pump control using 116-3526 or superseding 315-4412 |
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 an electrical voltage drop is found, keep the verified reference, measurements and test result in the service record. Approve 116-3526 from the complete old valve marking, 24v 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 fleet stock is replenished for planned service, 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 bulk order moves from sample to production, 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 a connector harness revision is compared, 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. A controlled sample review should confirm physical fit, connector engagement, coil current, leakage and the machine response in both normal and energized states. For this hydraulic pump solenoid valve, record warm oil behavior and response time as well as cold start operation. Retain the approved label photos and measurements so the production lot can be checked against the same acceptance record.
During a first article sample is reviewed, 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 contaminated hydraulic oil has been discovered, 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 24v 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.
