125-5773 and 125-5774 serve the same broad Caterpillar engine families but represent different electrical versions: 12V and 24V respectively. The distinction matters on 3204, 3304, 3306 and 3406-family equipment where several shutoff-solenoid designs may be encountered.
Item | Confirmed Information |
Product Type | Fuel shutoff solenoid |
OE / Reference Numbers | 12V: 125-5773; 24V: 125-5774 |
Electrical Version | 12V or 24V |
Application Scope | Caterpillar 3204, 3304, 3306, 3406B and 3406C engine families |
MOQ | 50 pcs |
Delivery Time | 7 - 15 Days |
Warranty | 12 Months |
A 3306 or 3406 engine description does not decide between 125-5773 and 125-5774. Confirm the old OE and voltage first, then compare the bracket, shaft and electrical-end arrangement to avoid applying the correct engine family to the wrong solenoid version.
Matching Point | Buyer Action |
125-5773 | Confirmed 12V shutoff-solenoid reference. |
125-5774 | Confirmed 24V shutoff-solenoid reference. |
Engine family | 3204, 3304, 3306, 3406B or 3406C supports the application review. |
Bracket and shaft | Compare mounting angle, hole positions and shaft-end geometry. |
Electrical end | Confirm the old voltage marking and terminal configuration. |
Distributors servicing 3306 and 3406 engines often hold several shutoff-solenoid references. The safest stock method is to identify each bin by full OE and voltage, then retain a terminal-end and bracket photo with the item record rather than relying on an engine-family label.
Service or Order Situation | Recommended Review |
Same engine, different OE | Keep each reference in a separate bin and verify the removed label. |
Voltage mark unreadable | Use machine electrical data and service documentation before ordering. |
Shaft end differs | Treat the part as a different configuration until dimensions and linkage are reviewed. |
Mixed service kits | Require voltage-specific inner labels so 12V and 24V units cannot be swapped during field issue. |
State 125-5773 12V or 125-5774 24V, add the engine family and quantity, and attach the old label, terminal, bracket and shaft photos.
RFQ Item | What to Provide |
OE / reference | 12V: 125-5773; 24V: 125-5774 |
Voltage | 12V or 24V required for the selected reference |
Application | Caterpillar 3204, 3304, 3306, 3406B and 3406C engine families |
Photos | Old label, electrical end, mounting area and complete removed part |
Commercial request | Quantity, destination market and packing requirement |
125-5773 is the confirmed 12V shutoff-solenoid reference.
125-5774 is the confirmed 24V shutoff-solenoid reference.
The confirmed scope includes 3204, 3304, 3306, 3406B and 3406C families, subject to OE, voltage and physical comparison.
More than one shutoff-solenoid configuration can be associated with a broad engine family. The removed OE, voltage, bracket and shaft must identify the correct item.
Stop the order and send measured shaft and linkage photos. A different end profile can prevent correct shutdown travel even when voltage matches.
Label each bin with the full OE and voltage, and keep a bracket-and-terminal reference image in the warehouse item record.
Send 125-5773 or 125-5774, the required voltage, Caterpillar engine details, quantity and removed-solenoid photos for quotation.
