2001-12E2U1B1S1A is a configuration-specific fuel shutdown solenoid for Woodward 2001/2003-series industrial diesel controls. The long code is functional data, not an optional catalog label: voltage, mounting, plunger, grounding, terminals, boot and spring family can change with individual suffix characters. The full removed-part code should remain intact on the inquiry, purchase order and carton label.

2001-12E2U1B1S1A indicates external 1/4-28 plunger thread, ungrounded electrical configuration, constant-volume boot family. Verify every suffix character on the removed unit.
Matching Point | Buyer Review |
Complete code | 2001-12E2U1B1S1A indicates external 1/4-28 plunger thread, ungrounded electrical configuration, constant-volume boot family. Verify every suffix character on the removed unit. |
Voltage | 12V and 24V versions; select by complete OE and old-unit marking |
Mounting | Compare flange/base style, hole centers and installed body angle. |
Plunger | Match thread, resting length, travel direction and connection hardware. |
Terminals and ground | Confirm terminal count and grounding method from service data; never rely on wire color alone. |
A correct voltage alone does not prove interchangeability. Terminal arrangement, grounding method, plunger thread, boot clearance and return spring can change across nearby Woodward or Syncro-Start codes, while pull/hold faults can produce the same start-then-stop symptom as a failed solenoid.
Observed Situation | Recommended Check |
Starts then stops | Check hold voltage after cranking and inspect pull/hold terminal assignment. |
Will not shut down | Confirm the plunger reaches the fuel lever's complete stop position. |
Coil overheats | Check incorrect voltage, restricted stroke and pull-winding timing. |
Boot contacts bracket | Compare body angle, boot family and available clearance. |
Code is partly unreadable | Use close label photos plus measured mount, thread and terminals before approval. |
Release the order only after electrical, mechanical and application evidence agrees with the removed assembly. The checklist below keeps fleet, distributor and service-team information on one approval record.
Approval Item | Required Information |
OE and voltage | 2001-12E2U1B1S1A / 2001-24E2U1B1S1A; 12V and 24V versions; select by complete OE and old-unit marking |
Application | Woodward 2001/2003-series industrial diesel controls |
Removed-part photos | Complete label, connector face, both bracket 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 the order. The 12V and 24V bodies may share mounting geometry, but their coils are not interchangeable. Confirm machine charging-system voltage at the old connector and label cartons by both OE and voltage to prevent mixed inventory.
Suffix characters identify mechanical and electrical features such as mounting, plunger thread, grounding, terminals, boot and spring family. Shortening the code can merge non-interchangeable versions in purchasing records. Photograph every readable character and keep the full string on the RFQ and carton label.
Voltage is only one control point. The replacement must also match mounting style, plunger thread, energized direction, terminal arrangement, grounding, boot clearance and required force. Compare the complete code and removed-part dimensions instead of selecting from 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 before replacing the solenoid.
Compare the full label, voltage, connector face, terminal count, mounting-hole centers, body orientation, output end, resting length and required travel. Add one wider installed photo showing nearby pump or linkage clearance; close product photos alone may hide the geometry that decides fitment.
Correct the reason the old unit failed before installation. Check supply voltage, pull/hold timing, linkage resistance, mechanical stops, terminal tightness and heat exposure. A new coil can fail quickly when the pull stage remains energized or the plunger cannot complete its designed stroke.
Send 2001-12E2U1B1S1A / 2001-24E2U1B1S1A, confirmed voltage, Woodward 2001/2003-series industrial diesel controls, old-label and connector photos, bracket and output measurements, quantity, destination and packing requirement. Mixed fleets should list each voltage and configuration on separate lines so technical approval and warehouse labeling remain traceable.
Send the complete OE group, confirmed voltage, Woodward 2001/2003-series industrial diesel controls, removed-part photos, measurements and order quantity for a fitment-focused B2B quotation.
