Woodward SA-3499-12 is the 12 volt shutdown solenoid with a side mounting bracket, grey moulded boot, threaded plunger with lock nuts and three flying leads. It is used on Woodward 1751ES applications. This aftermarket version has the same mounting and electrical connector as the original, so it plugs in and bolts on where the old one came off.
The same part is also sold as Woodward 1751ES-12E2ULB1S1.
Sold as one unit. Check the number on your old part, or in the parts manual for your machine, before ordering.

Engine will not start or will not stop
A failed fuel shutoff solenoid holds the fuel off (no start) or will not cut it (no stop). Check power at the plug first.
Engine cuts out
A weak pull-in or hold coil lets the solenoid drop out under vibration and the engine stalls.
Sticking plunger
Dirt and corrosion stop the plunger moving freely. Replacing the solenoid is quicker than freeing an old one.
Fleet spares
A spare solenoid on the van turns a no-start into a quick fix on site.

Yes, it is a direct replacement for the Woodward SA-3499-12 with the same fitting.
There is no fixed interval. It is changed when it fails, and many fail from water in the plug or chafed wiring rather than wear.
A fault code for this circuit, readings that jump or stay fixed, or a part that does not respond with power at the plug.
Read the fault codes, then check the plug and wiring for corrosion or a broken wire. A wiring fault reads the same as a failed solenoid.
Usually. Clear them after fitting and run the machine, so old codes are not mistaken for a new fault.
No. It is an aftermarket solenoid made to replace the Woodward SA-3499-12. It is not made by the original manufacturer; the number only shows what it replaces.
