3958160 and SA-4978-12 form a focused 12V shutdown-solenoid group for Cummins 6BT and 6BTA 5.9L service. The body, rod and bracket must still match the installed fuel-control arrangement because marine, generator and industrial packages can use different linkage geometry.
Item | Confirmed Information |
Product Type | Fuel shutdown solenoid |
OE / Reference Numbers | 3958160 / SA-4978-12 |
Electrical Version | 12V |
Application Scope | Cummins 6BT and 6BTA 5.9L engine applications with confirmed 12V configuration |
MOQ | 50 pcs |
Delivery Time | 7 - 15 Days |
Warranty | 12 Months |
Confirm 12V first, then compare the complete bracket, mounting-hole spacing, rod-end style, free length and connector orientation. An installed photo showing the solenoid beside the pump helps identify clearance and movement direction.
Matching Point | Buyer Action |
OE group | 3958160 / SA-4978-12. |
Voltage | 12V only for the verified group. |
Bracket | Compare angle, hole centers and installed clearance. |
Rod | Measure free length, thread or eyelet and required stroke. |
Pump layout | Show the linkage and fuel-control lever in one wider photo. |
Start-then-stop complaints often point to a missing hold feed, while no movement can come from supply, ground or a restricted rod. Measure voltage during both cranking and run stages and observe the linkage before replacing 3958160.
Service or Order Situation | Recommended Review |
Pulls then releases | Check the hold circuit, relay and connector resistance. |
No movement | Measure 12V at the solenoid and verify ground under load. |
Rod moves part way | Inspect linkage binding, bracket alignment and installed preload. |
Coil gets hot | Confirm the pull stage disengages after the commanded movement. |
Provide 3958160 or SA-4978-12, Cummins 6BT/6BTA engine data, voltage, bracket, rod, connector and quantity.
RFQ Item | What to Provide |
OE / reference | 3958160 / SA-4978-12 |
Voltage | 12V |
Application | Cummins 6BT and 6BTA 5.9L engine applications with confirmed 12V configuration |
Photos | Old label, connector face, mounting bracket, rod or cable end and one complete removed-part view |
Commercial request | Quantity, destination market and packing requirement |
Verified listings pair 3958160 with SA-4978-12 and a 12V supply for Cummins 6BT and 6BTA 5.9L applications. Put both the OE and voltage on the inquiry so the electrical version remains explicit.
No. Marine, generator and industrial packages can use different brackets or linkage positions around the same engine family. Match the old number, connector, mounting holes, rod end and available stroke before approval.
Many systems energize a strong pull stage only during cranking, then rely on a lower-current hold stage. If the hold feed, relay or connector fails, the rod returns and the engine may stop immediately after starting.
Record bracket-hole centers, body-to-rod orientation, resting rod length, thread or eyelet dimensions and full movement. A straight connector view and wider installed photo help verify wiring access and clearance.
Not on the current evidence set. Some market listings group nearby numbers, but a strong voltage-and-configuration mapping was not established, so the public OE group remains limited to 3958160 and SA-4978-12.
Send the old label, 12V confirmation, Cummins engine model and serial, pump-side installation photo, bracket and rod measurements, annual demand and shipment destination. Mixed configurations should be separated into different RFQ lines.
Send 3958160/SA-4978-12, 12V proof, Cummins 6BT data, mounting measurements and quantity for quotation.
