3864274 Stop Solenoid: Match the Label, Voltage and Supplied Scope
2026/10/11
The product page lists 3864274 as a 24 V stop solenoid and shows the marking 1751-2467U1B1S5A in the product title. Do not treat those markings as interchangeable until the installed unit, machine records and supplier documentation confirm the relationship. No pinout or wiring assignment is provided here.
Before you request a replacement quote
- Photograph the old solenoid label straight-on and record every number, voltage mark and manufacturer code.
- Record machine model, serial and engine identification. Confirm the failed component is the stop solenoid rather than a relay, harness or fuel-control issue.
- Compare mounting dimensions, plunger/end shape, connector body and any visible lead arrangement. A matching connector shape does not prove electrical compatibility.
- Ask for a written statement of what is supplied: solenoid only, connector/pigtail, mounting hardware or a larger assembly. Do not assume wiring terminals or pin functions.
Fault diagnosis versus part replacement
| Route | Use when | Cost, labor and downtime factors |
|---|---|---|
| Check supply and control circuit | Solenoid operation is uncertain or wiring/relay faults have not been excluded. | Diagnostic labor may prevent an unnecessary part order; machine availability depends on fault isolation. |
| Replace confirmed solenoid | Testing identifies the solenoid itself and part identity is verified. | Quote depends on solenoid-only versus connector/hardware scope; installation and functional check affect labor. |
| Repair wider fuel-stop circuit | Fault is traced to harness, relay or control side. | More components and diagnosis can extend downtime; a solenoid-only order may not solve it. |
Send clear photos of the installed label, connector, mounting face and machine plate. Ask the seller to confirm voltage and included components in writing. Do not connect a replacement based on appearance or guessed pinout.
