What should I ask for before buying a mixed batch of SANY spare parts for a remote Kazakhstan project?

Direct answer: Ask for a line-by-line candidate-number list, not a single SANY spare parts quotation. Each line should state the machine and assembly identity, the old part number or measured/photo identity where a number is missing, the supplied condition, the batch/lot or date reference, and the specific evidence that matches that part category. If that link is missing, a large document pack may still not prove which item is in the box.

Why this matters: On a remote Kazakhstan project, returns and inspections are slow. A wrong filter or seal can stop a machine; a mislabelled hose or track part can damage an assembly. The model name alone is not enough.

1. Create an item-to-record link before price

For each spare line, assign a candidate number or require the supplier to assign one. A candidate number is a short unique line identifier that connects the quotation line to one physical item or batch position. Ask every photo, label, record, certificate or test result to carry that same candidate number.

A useful request: Line 07, candidate number KZ-007. Attach the old part number, component photo and label photo, and state whether supplied as new or used.

This separates identity from price. It also shows whether a document pack is really item-linked or just a collection of general files.

2. Keep machine identity and part identity separate

Ask for the machine model and full serial number for the machine, and serial or model suffix for the major assembly where relevant: engine, hydraulic system, travel motor, final drive, track frame or working attachment.

For each part line, ask for:

• old part number from the removed part, if available;
• photo of the existing part or housing label;
• installation position and photos of the surrounding area;
• current catalogue revision or supersession record only if the supplier can produce it.

Do not accept SANY excavator filter or standard 22-ton machine part as a fitment confirmation. If the old part number is missing, say so and ask the supplier to record the missing information in writing instead of guessing.

3. Request only the evidence that the part category actually needs

Not every item needs the same documents. A filter and a track shoe do not create the same risk. Use the part group to decide the minimum evidence.

Filters

Filters are high-risk because the fitment may be engine, hydraulic or fuel system specific.

Ask for:

• filter part number and old part number;
• machine serial and engine/model code for engine or fuel filters;
• installation position photo;
• batch/lot and production or filling date if available;
• supplied condition: new, sealed, dry and undamaged.

A supplier statement that a filter is genuine SANY is not a traceability record. Ask whether the batch reference links to the candidate number.

Seals

Seals often fail because of material, hardness, groove fit or storage damage.

Ask for:

• old seal number or the housing/groove dimensions where the old number is missing;
• material grade or elastomer family if the supplier makes a specific claim;
• dimensions: inner diameter, outer diameter and section or measured photo;
• batch/lot or date code;
• supplied condition: no cuts, flattening, hardening or visible damage.

If material is important, request the applicable material certificate or a traceable batch reference. Do not accept a generic rubber seal description for a high-pressure or high-temperature position.

Hoses

Hoses need fitting identity, not just length and bore.

Ask for:

• hose part number and old number;
• length and bore, but only together with end fitting type and angle;
• pressure class or assembly rating if the supplier states one;
• layline photo and tag photo;
• date of manufacture or batch reference;
• supplied condition: no cracks, abrasion, kinked body or corroded fittings.

For hydraulic hoses, a written statement that a hose is suitable for the machine is weaker than a line-item match to the old hose number or an assembly drawing.

Undercarriage items

Undercarriage parts are dimension-critical and often mixed from different batches.

Ask for:

• part number and machine/application confirmation;
• critical dimensions: pitch, bushing bore/outer diameter, link count, track shoe width, bolt pattern where applicable;
• photos of the old part and any stamped marks;
• batch/lot or heat code if available;
• supplied condition: new, unused, or used/refurbished;
• any dimensional inspection report only where the supplier can provide it.

A track shoe can be the same width but wrong pitch or bolt pattern. Dimensional checks should match the old part or the applicable catalogue drawing.

4. Separate fitment, provenance, sample results and batch acceptance

Use five separate boxes for each high-risk line:

1. Identity: what is the part and old number?
2. Fitment: which machine and assembly position does it fit?
3. Provenance: what written source or traceability record says where the part came from?
4. Sample/result: was there a dimension, material or batch test, and which serial/lot does it cover?
5. Batch acceptance: is the whole candidate-number batch accepted, or only one sample?

A thick document pack can still fail if the certificate is for a different batch, or the dimensional report has no link to the candidate number. Ask: Which candidate number does this document belong to?

5. Put unresolved questions and dated written supply terms on the quote

Remote project supply should not depend on a phone call. Ask for dated written terms before shipment. Include:

• missing old part numbers and missing identity data;
• whether each line is new, unused, used or refurbished;
• whether supersession is allowed and how substitutions are approved;
• inspection and rejection window after delivery;
• packaging and marking requirements for transport to a remote site;
• documents that will be supplied with each candidate line;
• what the supplier will not provide.

These are procurement terms, not stock promises. Do not ask the supplier to guarantee availability or lead time unless it is in the current written supply terms. Unresolved questions should be visible: for example, line 11 old number not available; fitment to be confirmed by photo review before dispatch.

6. Procurement next step: collect missing evidence first, then decide

Use a short decision sequence for each line:

Observation: identity or fitment is incomplete. Evidence needed: missing old number, photo, dimension or batch reference. Next check: compare the item label or measure against the applicable SANY parts catalogue or supplied assembly record. Decision: accept, request more evidence, or reject the line.

If you are using an external commercial platform such as MechLink, use it to organise candidate-number enquiries and ask for current written stock and delivery information; do not treat a platform display as proof of authenticity, fitment, batch quality or final acceptance. MechLink is an external commercial service, not SANY, an authorised dealer, a certification body or a testing platform.

Parts Matching Support: If you send a matching request, include model + serial number + old part number + component/housing photos and any relevant labels or records.
