Spare Parts Identification Enquiry

Spare Parts Identification Enquiry

OWNED DECISION: Capture model, serial, part markings and photographs for a controlled compatibility review; do not turn unverified customer descriptions into confirmed part matches. MANDATORY ASSET: Working Parts Enquiry Form with Photograph Guidance.

01 — Direct answer

To identify a compressor spare part responsibly, collect the machine manufacturer, model and serial number, the existing component markings and revision, photographs taken safely, and the component’s installed location. A supplier or qualified technical reviewer must verify the proposed part against applicable OEM or approved cross-reference evidence before a compatibility statement or quotation is issued.

02 — Distinct page ownership

This page must not duplicate component catalogues or pretend an enquiry form itself determines compatibility.

03 — Intended audiences

Support plant maintenance teams, service technicians, procurement teams, rental-fleet maintainers and authorised resellers. Offer a quick path for known OEM numbers and an assisted path for unknown or damaged markings. Procurement-only users may have a purchase reference but not machine access; provide an explicit “details unavailable” path rather than encouraging guesses.

04 — Core user journeys

A: known model and original part number; B: known compressor but part number unreadable; C: component in hand with no machine details; D: legacy machine with superseded catalogue references; E: multiple identical-looking variants; F: urgent failed part with safe isolation confirmed; G: planned consumable kit enquiry; H: incompatible delivered item review. Each route ends in a review state, not an automatic match.

05 — Safety-first capture

The form must never require a user to remove guarding, loosen pressurised fittings, open live electrical enclosures or reach moving machinery to obtain a photograph. Ask for photos from safe accessible viewpoints only. If the component cannot be inspected safely, accept the machine nameplate and prior service documents and route to a competent technician.

06 — Machine identity

Capture manufacturer, exact model, serial number, year if known, compressor type, electric/diesel drive, equipment tag and optional original purchase reference. Serial numbers are especially important where revisions changed mid-model. Treat OCR or manually transcribed text as provisional until checked against a legible source.

07 — Component identity

Capture component category, installed location, original markings, engraved/cast/stamped codes, manufacturer brand, label revision, approximate dimensions, connector or port arrangement, and quantity. Distinguish numbers printed on packaging from numbers permanently marked on the part.

08 — Service context

Ask whether the request is scheduled replacement, failed part, suspected mismatch, overhaul kit, obsolete component or stock replenishment. Record symptoms as customer observations only.

09 — Known number does not equal compatibility

A matching visible part number may still be unsuitable if the machine serial range, electrical rating, firmware, seal material, pressure rating or revision differs. Preserve all candidate numbers and require a technical reviewer to resolve applicability. Do not promise interchangeability from appearance alone.

10 — Supersession chain

Where OEM catalogues identify superseded numbers, record old number, new number, effective serial range, source document revision, adapter or kit requirements and whether a one-way replacement rule applies. Do not infer that a new part is backward compatible simply because a supplier listing says “replacement”.

11 — Part family-specific evidence

Air/oil separators need geometry and performance applicability; filters need element dimensions and media specification; lubricants need OEM-approved grade and compatibility; sensors require electrical range and connector; valves require pressure/temperature/material; VFD/controllers require ratings and software compatibility. The form branches to ask only the evidence appropriate to the selected category.

12 — Nameplate photograph guidance

Ask for one full equipment photograph and one readable nameplate close-up, captured without dismantling. Ensure model and serial remain legible, avoid glare, and include a second image when markings are embossed. If the plate is damaged, offer typed transcription plus service-history attachment; mark identity unverified.

13 — Component photograph guidance

Request a general view showing where the part sits, close-up of its markings, connector/port face and an optional dimension reference. Do not ask users to place rulers near moving equipment. Images must not expose confidential documents, employee faces or customer site security features unnecessarily.

14 — Dimensional data

Where needed collect length, outside diameter, thread designation, mounting-hole centres, port count, connector keying or seal geometry with units and measurement method. A user-entered dimension is indicative until verified; a 1–2 mm discrepancy can be decisive for some parts. Do not prescribe universal tolerances.

15 — Electrical and controls compatibility

For motors, contactors, solenoids, sensors, VFDs and controllers, collect supply voltage, frequency, current/power rating, connector type, control protocol and firmware/hardware revision when available. Do not ask unqualified users to test energized terminals or extract internal control modules.

16 — Lubricant and material compatibility

For oils, elastomers and wetted parts, record machine family, operating conditions, existing lubricant or material where known, contamination concerns and manufacturer guidance. Avoid universal mixing claims. Technical review must assess chemical, temperature and application suitability.

17 — Consumables and kit selection

Offer categories for routine service kit, air filter, oil filter, separator, belt, drain, gasket and seal. Ask for service interval and serial where available, but do not derive an OEM kit solely from operating hours. Bundle contents must be listed and revision-controlled.

18 — Legacy and discontinued machines

Provide an explicit route for unreadable nameplates, missing manuals and obsolete part numbers. Status should be “engineering review required” rather than “no match” or a fabricated substitute. Where replacement is not supportable, record the limitation and recommend qualified assessment.

19 — Photo evidence quality gate

Accept images only if readable, sufficiently lit and relevant. A photo can prove markings or visible geometry but not pressure rating, internal material, remaining life or electrical compatibility. If the evidence is inadequate, send a precise resubmission request identifying which view or marking is missing.

20 — Attachment formats and security

Specify deployment-configured allowed image/PDF formats, maximum per-file and aggregate sizes, file-count limit, malware scanning, MIME/content validation, safe renaming and private storage. Never execute uploaded content or expose raw attachments through public predictable URLs. Exact size thresholds require host configuration confirmation.

21 — Mobile upload experience

Use native camera and file picker; allow multiple photos with preview, delete and retry. Preserve typed fields after an upload failure. Display upload progress and actionable error messages. Avoid forcing high-resolution originals where a readable compressed version suffices; do not degrade markings beyond legibility.

22 — Accessibility

Use explicit field labels, helpful examples, descriptive errors, logical keyboard focus and status announcements for uploads. Do not rely on colour alone. Image instructions must have text alternatives. Ensure touch targets, zoom and portrait layout remain usable on common mobile devices.

23 — Required versus optional fields

Required: contact channel, request category, at least one machine or part identity route, consent acknowledgement and part description. Conditionally required: machine serial for serial-controlled parts unless “unknown” is selected; electrical ratings for electrical candidates unless unavailable. Optional: location details, quantities, urgency and supporting documents. Do not block valid enquiries because a customer lacks the very identification they need help obtaining.

24 — Unit and field validation

Validate numeric quantities as positive integers, dimensions with units, email syntax, phone format appropriate to jurisdiction, attachment types and maximum lengths. Keep manufacturer/model free text to support legacy machines. Use server-side validation regardless of client-side checks.

25 — Privacy and purpose limitation

Collect only information needed to assess and respond. Provide a clear notice covering use, retention, processors and contact method. Serial numbers and site images can reveal commercial assets; limit access by role and retain only under approved policy. No marketing consent should be bundled into a mandatory technical-enquiry checkbox.

26 — Enquiry routing

Route based on part category, machine family and completeness. Example queues: mechanical/airend, filtration/consumables, electrical/controls, portable diesel and unidentified/legacy. Routing is a workflow design requiring real queue owners; do not invent named staff or service-level commitments.

27 — Status model

Use Draft → Submitted → Intake validated → Evidence requested / Technical review → Candidate identified → Compatibility verified / Not verified → Quote authorised / Unable to supply → Closed. Preserve timestamps, owner, decision notes and customer-facing status. “Candidate identified” must never be rendered as “guaranteed fit”.

28 — Acknowledgement

On successful submission show a unique enquiry reference, summary of captured request, acknowledgement of receipt and instructions for supplying missing photos. Email or SMS notifications require verified configured delivery. Do not promise a fixed response time or stock availability.

29 — Failure and retry

Handle file upload timeout, oversized file, rejected format, malware detection, routing outage, duplicate submission, network interruption and unavailable mail service. Avoid silent success. Provide a safe retry path without duplicate records and a fallback contact route only if an approved contact channel exists.

30 — Spam and abuse resistance

Apply rate limits, bot controls compatible with accessibility, CSRF protection, attachment scanning, sanitisation and safe logging. Do not expose customer documents or enquiry IDs in public search indexes. Monitor repeated failed submissions without collecting unnecessary tracking data.

31 — Duplicate detection

Flag likely duplicates using contact, equipment identity and recent request window, but do not automatically merge different part positions or quantities. Let authorised staff link related enquiries and preserve separate histories.

32 — Review decision matrix

Technical reviewers compare verified model/serial applicability, OEM documentation, original and candidate numbers, geometry, electrical/material requirements and revision notes. A reviewer must record evidence and unresolved questions before any confirmed match. A supplier claim without applicable documentation is not sufficient for a high-consequence component.

33 — Quotation boundary

The form requests review and may lead to a quote; it does not show a binding price, confirm stock, reserve inventory or promise shipping. Quotations must independently confirm part identity, quantity, currency, taxes, delivery terms, exclusions and validity under business policy.

34 — Technical risk escalation

Escalate pressure-retaining parts, safety devices, critical controls, load-bearing components and uncertain replacements to appropriately qualified reviewers. If exact fit or rating cannot be confirmed, return “not verified” with a clear evidence request rather than guessing.

35 — Return and mismatch learning

If a delivered part is reported incompatible, capture order reference, original verified evidence, received part markings, installation status and discrepancy. Keep a non-punitive correction trail and route through approved returns/service processes; never recommend forcing fit or modifying safety-critical parts.

36 — Analytics without overcollection

Track category selection, submission completion, validation errors, attachment failure, evidence-resubmission frequency and technical review outcome. Avoid collecting serial numbers, photos or free-text fault descriptions in general analytics. Use aggregated measures to improve the form.

37 — Technical content cross-links

Links should help users gather correct evidence; they must not replace review by a qualified person.

38 — Form ownership and change control

Assign product owner, technical owner, privacy owner and developer owner. Maintain field IDs, validation rules, routing table, attachment policy, consent text version, release date and change log. Re-test affected branches after every change.

39 — Standards-aware implementation

Use current accessibility, privacy, secure file-upload and data-retention requirements applicable to the deployment jurisdiction. Manufacturer documentation governs model-specific compatibility. Do not claim ISO certification, OEM approval or legal compliance from the existence of this specification alone.

Workflow

42 — Worked enquiry A: filter element with ambiguous dimensions

ILLUSTRATIVE ONLY. A user submits an air-filter photo and a 150 mm approximate outside diameter but no machine serial. Two catalogue candidates share similar dimensions and differ in sealing geometry. The correct response is “candidate only; provide machine model/serial and seal-face photo”. Neither a visual match nor approximate size justifies compatibility approval.

43 — Worked enquiry B: superseded separator part

ILLUSTRATIVE ONLY. A service record lists part X-100 and a supplier catalogue lists X-101 as a replacement. Before approving, the reviewer checks OEM applicability by serial range, housing geometry, gasket/earthing requirements and catalogue revision. The record retains the supersession source and whether a kit is needed. No real part numbers or OEM approvals are claimed.

44 — Worked enquiry C: solenoid coil rating mismatch

ILLUSTRATIVE ONLY. An uploaded photograph shows a 24 V DC coil while the proposed candidate is 230 V AC. The workflow must reject the candidate pending a correct electrical rating and valve-body compatibility review, even if the mechanical dimensions look similar. The customer should not be asked to energise the component to prove its identity.

45 — Worked enquiry D: obsolete portable compressor

ILLUSTRATIVE ONLY. The machine has a damaged nameplate, but the customer provides an engine serial, previous invoice and three component photographs. The record is routed to legacy equipment review; a part match remains unverified until authoritative evidence supports it. If evidence cannot be recovered, return a qualified limitation rather than inventing an interchangeable part.

46 — Worked enquiry E: service kit for two serial ranges

ILLUSTRATIVE ONLY. Two compressors have the same family name but different serial ranges. The user requests one combined service kit. The reviewer must check kit contents for each serial range and may issue two distinct verified part lists. A single generic kit is not presumed appropriate.
