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

Ask the supplier to give every order line a candidate number and a written line-level evidence sheet. For each candidate, request the machine or assembly identity, the old part number and photos where possible, the SANY part number with catalogue revision and documented supersession, the supplied condition, the batch or date code, and the specific document that supports that line. Do not accept a model name alone or a large document pack as proof of fitment, batch quality, or authenticity.

A mixed batch fails more often because of weak line-to-record links than because of missing paper volume. The checklist below separates identity, fitment, provenance, and batch acceptance.

1. Build a line-level candidate list first

A candidate number is a unique reference assigned to one part, kit, or assembly line on the quotation. It keeps records from becoming mixed across similar parts.

Minimum line-level identity

For each line, ask the supplier to state:

• candidate number
• machine model and suffix
• machine PIN or serial number where available
• component or assembly serial number where applicable
• old part number from the removed part, if available
• installation position and clear component or housing photos
• SANY part number, catalogue revision, and any documented supersession chain
• supplied condition: new, unused surplus, refurbished, or used

Model alone never confirms fitment. A serial number or an old part number is usually a stronger starting point for a remote project because it links the part to a specific machine or assembly.

Missing identity is not a small detail

If an old part number is missing, request more evidence instead of guessing from a component photo. For example, a filter housing photo may narrow the filter group but does not always confirm the correct micron rating or bypass setting.

2. Keep five evidence types separate

Part identity

This is the part number, revision, and supersession. It answers what the part is.

Fitment

This is the link to the machine or assembly: model/suffix, serial number, old part number, installation position, and applicable catalogue revision.

Provenance

This is the written origin or supply record, if available. A supplier statement is useful but is not the same as an auditable record.

Batch reference

This is the lot, batch, or date code that ties the physical item to a production or packaging batch.

Sample results

If a test certificate is provided, it must be linked to a candidate number and batch reference. A generic certificate for the same part family is weaker than a lot-specific record.

Do not let a supplier mix these categories in one sentence such as 'OEM number, new stock, quality assured'. Ask which document supports each claim.

3. Tailor evidence by part family

Not every item needs the same depth of evidence. A low-pressure seal may need less than a high-pressure hydraulic hose or a final-drive seal set.

Filters

Ask for the filter part number, the housing or engine model, micron rating, bypass or flow/pressure data if applicable, batch code, and any batch test record offered. Fuel-water separation and hydraulic filters deserve more attention than a basic air cleaner element if the project depends on fuel quality or hydraulic cleanliness.

Seals

Ask for the kit or individual seal part number, material designation, hardness if applicable, dimensions or drawing, and batch/date code. A generic 'seal kit for SY model' is not enough because the same model can use different cylinder or final-drive seal configurations.

Hoses

Ask for the hose assembly number, dash size, length, fitting type and orientation, working pressure class, standard followed, and date code. A photo does not prove pressure capacity or fitting angle.

Undercarriage

Ask for the track group or undercarriage part number, link count, pitch, bushing outer diameter, shoe width, and wear percentage if used. For new items, request the batch or heat number and any dimensional or hardness record supplied.

4. Reject a thick document pack without an item-to-record link

A large PDF can still miss the point. If no page maps a test report, material certificate, or batch code to candidate number 003, the evidence is not line-level.

Ask the supplier to add a short evidence map: each candidate number, the document title, the document date, and the page or certificate reference that applies to that line.

If documents are generic

Request missing evidence instead of guessing. For example, if the undercarriage line has a material certificate but no heat number match, mark it as unresolved until the supplier links the heat number to the candidate or the track group serial.

5. Put unresolved questions and supply terms in writing

A remote Kazakhstan project needs a dated written supply record before acceptance. Ask for terms that cover:

• how missing or unlinked evidence is handled
• how rejected lines are returned or replaced
• who pays for disputed inspection or testing
• packaging and record retention for the project site
• acceptance period after delivery

This is a procurement matter. Do not rely on a telephone statement. List unresolved questions in the same written request, such as: 'Does the supersession statement for candidate 004 include the old part number?' or 'Is the hose date code from the individual assembly or only the outer carton?'

6. Use a short check sequence

A useful order of thinking is:

1. Observation: this line looks right but no serial link exists.
2. Evidence needed: old part number, machine serial, or assembly serial and catalogue revision.
3. Next check: ask supplier to mark the candidate number and provide a named document.
4. Procurement decision: accept only if the line-to-record link meets the written terms.

7. Parts matching support

For a mixed batch, a structured enquiry can help. MechLink, an external commercial parts-matching service, may be used to organise candidate-number enquiries. It is not a SANY official site, authorised dealer, service centre, certification body, or testing platform. If you use it, send model and serial number, old part number, component or housing photos, and any labels or records. Ask separately for current written stock and delivery information because this article does not state availability. The support note can help reduce missing identity, but it does not replace the supplier's written line-level evidence.
