12V: 125-5771 / 9X-5312; 24V: 125-5772
OE-Equivalent Replacement Quality

125-5771 is the 12V version and 125-5772 is the 24V version for Caterpillar 3114, 3116 and 3126 engine demand. Both are identified as two-terminal intermittent-duty solenoids, so the duty marking and terminal arrangement deserve the same attention as the voltage.
Item | Confirmed Information |
Product Type | Fuel shutoff solenoid |
OE / Reference Numbers | 12V: 125-5771 / 9X-5312; 24V: 125-5772 |
Electrical Version | 12V or 24V |
Application Scope | Caterpillar 3114, 3116 and 3126 engine applications |
MOQ | 50 pcs |
Delivery Time | 7 - 15 Days |
Warranty | 12 Months |
The 12V reference 125-5771 can also appear with 9X-5312 in service records, while 125-5772 identifies the 24V version. Buyers should keep the reference, voltage and two-terminal configuration together through sample approval.
Matching Point | Buyer Action |
125-5771 / 9X-5312 | Confirmed 12V reference group. |
125-5772 | Confirmed 24V reference. |
Terminal count | Compare the two-terminal layout and insulator positions. |
Duty information | Confirm the intermittent-duty marking on the removed part and quotation. |
Engine record | Use Caterpillar 3114, 3116 or 3126 as supporting application information. |
A removed solenoid with another terminal count, different end-cap arrangement or incompatible duty marking should not be forced into the 125-5771 / 125-5772 OE family. The differences can indicate a separate configuration even when the engine is listed as 3114, 3116 or 3126.
Service or Order Situation | Recommended Review |
Different terminal count | Stop the match and provide a clear electrical-end photo. |
No readable OE label | Send voltage, dimensions, terminal layout and mounting photos for review. |
Duty marking differs | Do not assume interchangeability; record the complete marking before quotation. |
Two voltages in one order | Use separate lines, sample photos and carton labels for 125-5771 and 125-5772. |
Specify 125-5771 / 9X-5312 12V or 125-5772 24V, then provide engine family, terminal photo, duty marking, mounting view and quantity.
RFQ Item | What to Provide |
OE / reference | 12V: 125-5771 / 9X-5312; 24V: 125-5772 |
Voltage | 12V or 24V required for the selected reference |
Application | Caterpillar 3114, 3116 and 3126 engine applications |
Photos | Old label, electrical end, mounting area and complete removed part |
Commercial request | Quantity, destination market and packing requirement |
125-5771 is the 12V version and 125-5772 is the 24V version. The purchase line should never leave the voltage unstated.
9X-5312 is associated with the 12V 125-5771 configuration. Include the old marking and terminal photo when using that reference.
The end-cap and terminal positions help distinguish the configuration from other Caterpillar shutoff solenoids used on similar engine families.
The replacement should agree with the duty information on the removed solenoid and the approved specification. Do not replace it with an unconfirmed continuous-duty item.
No. Both voltage versions can appear in 3114, 3116 and 3126 demand, so the OE number, voltage and terminals must decide the order.
List 125-5771 12V and 125-5772 24V on separate lines, approve one terminal photo for each and require voltage-specific carton labels.
Send the voltage-specific 125-5771 or 125-5772 reference, engine information, quantity and terminal and duty-marking photos for quotation.
