Product Core Brief
- Model: 5501-1432
- Brand: Woodward
- Series: Woodward gas turbine / governor control hardware
- Core Function: Serves as a defined hardware article within a Woodward turbine control or governor assembly, replacing an identical OEM-coded position.
- Product Type: Turbine control hardware / OEM spare article
- Key Specs: Woodward part number 5501-1432 | Revision-controlled article | Assembly or cabinet mounting
- Condition: New Original / New Surplus (condition stated per line item on quotation)
Transparency note: Woodward 5501-series numbers identify the article and its revision, not a public datasheet. Confirm the exact article description from your Woodward parts list or the nameplate on the unit being replaced before ordering.

Product Introduction
The 5501-1432 is a Woodward part-number coded hardware article used as a spare in gas turbine and governor control assemblies. It is specified by part number and revision rather than by a public catalog type.
The real risk is not the article — it is ordering a revision that does not match the assembly. Pull the nameplate from the unit being replaced and quote against that, not against a search result.
QA & Testing SOP
Identical for new original and surplus. No exceptions.
- Inbound verification. Part number, revision, and date code photographed and matched against the customer’s Woodward parts list. Articles with mismatched revision labels are quarantined.
- Physical inspection. Connectors, pins, and solder joints examined under magnification for rework, oxidation, or bent-pin damage.
- Bench power-up. Powered through a current-limited supply where the article permits; quiescent current logged against the OEM baseline.
- Functional check. Verified on an OEM-compatible test setup where available; otherwise a documented continuity and insulation check is performed and recorded.
- Anti-static packaging. Moisture-barrier bag, desiccant, ESD label. Signed test record packed with the unit.
Installation Pitfalls & Guide
❗ Revision mismatch. Two units can share the same base part number and differ in PCB revision. Confirm the revision on the nameplate, not the packaging label.
❗ Assembly-level dependency. Some 5501 articles are calibrated or configured as a set with a partner unit — for example, a matched pair on a dual-channel actuator loop. Replacing one side alone can produce a fault that looks like a defective part.
❗ Connector seating and torque. A partially seated connector or an under-torqued terminal produces intermittent signal loss that is routinely misdiagnosed as article failure.
❗ Vibration and mounting. Turbine enclosures are high-vibration environments. Loose mounting hardware will damage the replacement on the same timeline as the original.
Replacement sequence:
- Pre-install — Confirm safe unit state, apply lockout/tagout, photograph the nameplate and mounting position.
- Removal — Release retention fully, extract straight, never pry against connectors.
- Install — Seat fully, torque fasteners to OEM specification, confirm no visible gap.
- Power-on test — Clear faults, verify communication with the parent controller, and complete a functional or trip test before returning to service.
Technical FAQ
Can I substitute a different 5501 revision if the exact one is unavailable? Only after checking the Woodward parts list. Revision differences can change pinout, firmware, or calibration, and a mismatch may pass power-up yet fail during a control demand.
Is this article hot-swappable? That is determined by the parent assembly, not by the article itself. Where the OEM procedure does not explicitly allow it, treat it as a shutdown replacement.
Why does the replacement show a fault after install? Most often it is not the article. Check connector seating, revision match, partner-unit status, and the parent controller’s fault log before condemning the part.
What warranty applies? New original articles carry standard coverage as stated on the quotation. Surplus units carry a shorter, disclosed term confirmed before payment.
Is the 5501-1432 still available from Woodward? Availability for 5501-series articles increasingly depends on channel inventory rather than direct production. That makes revision confirmation and lead-time disclosure more decisive than unit price on this part.
