2003ES-12E7U1B2S1A is a coded shutdown solenoid for Woodward-controlled industrial diesel engines. The full number is functional data: voltage, mounting, plunger, grounding, terminals, boot and spring can change with individual suffix characters. Keep the complete code intact on the RFQ, purchase order and carton label.
Item | Confirmed Information |
Product Type | Fuel shutdown solenoid |
OE / Reference Numbers | 2003ES-12E7U1B2S1A / 2003ES-24E7U1B2S1A |
Electrical Version | 12V and 24V versions; select by complete OE and old-unit marking |
Application Scope | Woodward-controlled industrial diesel engines |
MOQ | 50 pcs |
Delivery Time | 7 - 15 Days |
Warranty | 12 Months |
Retain every character in 2003ES-12E7U1B2S1A. Its voltage and configuration suffix identify a specific electrical and mechanical build; compare the complete old label, mounting, terminals, output end and working travel before approval.
Matching Point | Buyer Review |
Complete reference | 2003ES-12E7U1B2S1A / 2003ES-24E7U1B2S1A |
Voltage | 12V and 24V versions; select by complete OE and old-unit marking |
Mounting | Compare flange/base style, hole centers and installed angle. |
Plunger/output | Match thread, resting length, direction and hardware. |
Terminals/ground | Confirm terminal count and grounding method; never rely on wire color alone. |
Check the electrical command, component response and final mechanical movement as separate observations. This prevents a wiring, control-module or linkage fault from being mistaken for a failed replacement part.
Observed Situation | Recommended Check |
Starts then stops | Check hold voltage after cranking and pull/hold terminal assignment. |
Will not shut down | Confirm the output reaches the fuel lever's complete stop position. |
Coil overheats | Check voltage, restricted stroke and pull-winding timing. |
Boot contacts bracket | Compare body angle, boot family and available clearance. |
Code partly unreadable | Use label photos plus measured mount, thread and terminals. |
Release the order only after electrical, mechanical and application evidence agrees with the removed assembly.
Approval Item | Required Information |
OE and voltage | 2003ES-12E7U1B2S1A / 2003ES-24E7U1B2S1A; 12V and 24V versions; select by complete OE and old-unit marking |
Application | Woodward-controlled industrial diesel engines |
Removed-part photos | Complete label, connector face, both mounting sides and output end |
Measurements | Hole centers, body clearance, resting output length and working travel |
Commercial details | Quantity, destination market, packing and marking requirement |
Keep the complete voltage-specific reference and old-unit marking on every order line. Similar housings do not make different coils interchangeable. Measure system voltage at the original connector during operation, then label inventory by both OE and voltage so mixed fleets cannot receive the wrong electrical version.
Use 2003ES-12E7U1B2S1A / 2003ES-24E7U1B2S1A as the first control, then compare the old label, voltage, connector face, mounting-hole centers, output end and operating direction. Record the engine or machine model and serial number, but do not use the model name alone because production changes can introduce another shutdown arrangement.
The suffix can encode mounting, plunger thread, grounding, terminals, boot and spring family. Shortening the code can merge non-interchangeable parts in purchasing records. Photograph every readable character and retain the full string on the RFQ, order and carton label.
Voltage is only one control point. Mounting style, plunger thread, energized direction, terminal arrangement, grounding, boot clearance and required force must also agree. Compare the complete code and removed-part dimensions instead of selecting by coil voltage alone.
The pull circuit may move the plunger during cranking while the hold circuit fails after the start signal is released. Measure hold-terminal voltage under load, inspect relay logic and connector resistance, and confirm the plunger reaches full travel.
Compare the full label, voltage, connector face, terminal count, mounting-hole centers, body orientation, output end, resting length and working travel. Include one wider installed photo showing pump, lever or surrounding clearance because close product images can hide the geometry that decides fitment.
Correct the original failure cause before installation. Check supply voltage, pull/hold timing, linkage resistance, mechanical stops, terminal tightness, heat and moisture exposure. A new unit can fail quickly when the high-current stage remains energized or the output cannot complete its designed stroke.
Send the complete reference group, confirmed voltage, Woodward-controlled industrial diesel engines, removed-part photos, measurements and order quantity for a fitment-focused B2B quotation.
