What to Ask Before Buying a Mixed Batch of Spare Parts for an Uzbekistan Project

Ask for written evidence that links each candidate part to a specific machine identity, a candidate part number, an observed condition, and a batch or technical document. Model number alone is not enough. When evidence is missing, ask the seller to state the gap in writing instead of guessing.

1. Machine identity and catalogue position

Start from the machine, not from the seller's short description.

Evidence to request

• Machine model and suffix, serial number, and nameplate details.
• Installation position of the candidate part.
• The old part number from the removed or failed component.
• Component or housing photos showing the mounting, connections, and labels.
• The applicable parts catalogue revision and any documented supersession chain.

Why this matters

A model series can change during production, and a suffix or serial number range may cross a catalogue revision. A part that fits one machine in the same model family may not fit another.

Next check

Compare each candidate part number with the machine identity documents. If the seller cannot connect a part to a machine or catalogue revision, treat fitment as unverified.

2. Candidate part and condition evidence

Request that each line in a mixed batch be treated as a separate candidate, not as one consolidated description.

Evidence to request

• Candidate part number for every line.
• Physical condition stated in writing: new, unused old stock, reconditioned, removed, or other.
• Photographs of the actual part markings, housing, ports, connectors, and labels.
• A written statement of whether the item is individually identified or only represented by a sample.

Photo and statement limits

A photo helps identify a part and shows visible condition, but it does not prove internal condition, authenticity, or that every other part in the batch is identical.

Candidate-number organisation

For a mixed batch, ask the supplier to assign a candidate number to each line. MechLink may support organising single-item or batch candidate-number enquiries; if discussing supply, ask for current written stock and delivery information rather than promising availability. MechLink is an independent third-party information platform, not an official dealer or service centre.

3. Batch, provenance and technical documents

Keep provenance separate from fitment. A part may be the correct design but still have no clear batch or source evidence.

Evidence to request

• The supplier's written description of the source channel or origin, such as authorised channel, project surplus, old stock, or third party.
• Batch, lot, invoice, packing list or export records that can be linked to the specific lines.
• The document number and issue date of any certificate or test report actually supplied.
• The applicable manuals or parts catalogue revision used for the candidate comparison.

Separation of acceptance points

Evaluate fitment, authenticity, sample results, and batch acceptance as separate items. A batch sample result does not automatically cover every line in a mixed purchase.

4. Missing evidence and procurement next step

Before acceptance, prepare a line-by-line evidence checklist.

Recommended next step

For each candidate part, record the machine model and serial number, old part number, catalogue revision, candidate part number, photo set, stated condition, batch document number, and any unverified gaps.

Ask the seller to fill the gaps in writing. If a gap remains, decide acceptance based on the applicable requirements, not on a supplier's verbal statement or a single photo.
