Use the 3E-3748 technical image to compare dimensions and hydraulic states with the discontinued factory valve and the intended Caterpillar block.
Control 3E-3748 replacement through the Caterpillar serial record, measured coil voltage, valve-group geometry, 350 bar duty and two-position three-way circuit.
Approval Point | Buyer Review |
Reference Control | 3E-3748 |
Electrical Control | 12V product version; verify old valve; verify at the connector under command |
Mechanical Fit | Compare thread or flange, cartridge length, sealing lands and installed clearance |
Functional Control | Confirm normal state, energized state and hydraulic port relationship |
Application Evidence | Caterpillar 950F, 960F, 966F, 970F, 980F, 980G, 988F, D10R, D11R, R2900, 24H and related official compatible models |
For repeated sticking or leakage, evaluate connector supply, oil cleanliness, cartridge movement, seals and cavity condition before rejecting the replacement group.
Observed Situation | Recommended Check |
No hydraulic response | Check command voltage, connector, coil and whether the cartridge moves. |
Slow response | Review oil cleanliness, filter condition, viscosity and connector voltage under load. |
Reversed response | Compare normal and energized circuit states with the machine schematic. |
External leakage | Inspect seals, cartridge surface, bore condition and seating depth. |
Repeated coil heating | Check voltage, resistance, duty cycle, contamination and incomplete spool movement. |
Approval Item | Required Information |
Old Part Evidence | Complete label, connector face, mounting or cartridge side and one installed view |
Machine Evidence | Caterpillar 950F, 960F, 966F, 970F, 980F, 980G, 988F, D10R, D11R, R2900, 24H and related official compatible models |
Measurements | Thread or flange, cartridge length, seals and installed clearance |
Electrical Evidence | 12V product version; verify old valve; measured under the actual command |
Commercial Evidence | Quantity, destination, packing, labeling and inspection requirements |
Discontinued factory status makes configuration control more important because available replacements may come from different production routes. Keep the complete 3E-3748 reference, machine serial number, removed-valve photographs, connector and hydraulic details with the order. Approve a physical sample and operating function before accepting volume supply rather than relying on the part number alone.
The listed product information shows 12V, but the old valve must still confirm the voltage. Read the coil marking and measure supply during command on the Caterpillar machine. Keep any discrepancy on hold until resolved. A broad machine application does not justify installing a 12V coil where the removed configuration uses another electrical rating.
Machines such as 950F, 960F, 966F, 970F, 980F, 980G, 988F, D10R and D11R can differ by production arrangement and valve location. Use the full serial number and parts diagram to identify the installed 3E-3748 function, then compare the removed group. The model list alone is not universal fitment approval.
Confirm the listed 350 bar capability, two-position three-way circuit, cartridge geometry, sealing lands and connector relationship. Compare normal and energized flow paths with the machine schematic. Pressure rating does not compensate for a different circuit, and a matching external body cannot guarantee that the internal passages align with the Caterpillar valve block.
Maintain oil filtration at 25 micrometres or better and inspect contamination when the old valve sticks. Clean the cavity, protect seals and start the thread without force. Apply 34 to 37 Nm only after correct seating. Dirt, damaged seals or distorted installation can cause leakage and slow switching that resembles an electrical fault.
Provide the machine model and serial number, valve location, complete old marking, coil voltage, connector face, cartridge and seal dimensions, circuit information and required quantity. The sample record should include resistance, controlled actuation and leakage checks. Retain those results for repeat orders because discontinued-part supply requires consistent comparison with the accepted configuration.
Provide 3E-3748, machine model and serial number, old coil marking, connector and valve-group photographs, hydraulic details, quantity and destination.
