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

Before payment, ask for a line-by-line schedule that connects each spare part to a specific machine or assembly: serial/nameplate evidence, old part number, candidate replacement number, supplied condition, and batch/date references where they exist. Then request only the dimensional, material or test records that the individual order line actually requires. The goal is not a thicker document pack; it is a clear item-to-record link.

1. Start with an item-to-record link, not a model number

A model name is not enough to confirm fitment. A mixed batch may contain parts for different machines or serial ranges, even if all are labelled SANY. Ask the seller to show each order line against the machine or assembly identity it came from or is intended for.

For each line, the most useful start is: machine model and suffix, serial number or nameplate photo, assembly position, removed or old part number, and the candidate replacement number. Add photos of the component, housing or label if the removed part number is unreadable.

If a line says only that it fits a SANY excavator, leave it as unresolved until the seller supplies the missing identity evidence. Do not guess from appearance.

If the part number is superseded or equivalent

Ask whether the candidate is direct, superseded or a non-OEM equivalent. For supersession, request the catalogue revision or written cross-reference. If no documented supersession exists, treat the line as an unconfirmed candidate.

Parts Matching Support

If the candidate numbers become confusing across a mixed batch, an external commercial service such as MechLink can help organise the enquiry around model + serial number + old part number + component/housing photos and relevant labels. It is not a SANY official database, dealer or certification body, and it does not confirm fitment or authenticity. Kazakhstan Phone / WhatsApp: +77026412810.

2. Change the questions by commodity: filters, seals, hoses, undercarriage

The useful evidence depends on the failure mode and fit interface, not only the component category.

Filters

Ask for the housing interface and element dimensions, seal or gasket arrangement, thread or cap fit, and any bypass or media difference only if the machine application requires it. Request the batch or date code and a packaging label photo. A filter photo is not enough to confirm internal construction.

Seals

Ask material family, hardness and key dimensions, plus the groove or housing position. For a seal, a part number in a plastic bag does not prove material. If the old seal is damaged, keep the housing photo and measurement request open rather than accepting a lookalike.

Hoses

Ask end fitting type, thread or seal form, measured hose length, and service pressure class or relevant standard if the order calls for a tested assembly. Ask whether any pressure test or assembly record is line-specific, not a generic factory certificate.

Undercarriage

Ask track group or serial range, link pitch and pin or bushing dimensions where relevant, shoe or bolt pattern if included, and measured wear condition for used items. For new undercarriage components, ask for the manufacturer marking or reference that connects the part to the order line.

3. Separate fitment, provenance, batch and acceptance

A common mistake is accepting a large document pack that has no line-to-record link. A batch certificate for one filter can sit in the same file as an undercarriage invoice and prove nothing about either line unless the document names the item, candidate number, batch or date code and quantity.

Treat these claims separately: fitment identity, supplied condition, batch or provenance, sample or measurement results, and acceptance criteria. A supplier statement that a part is original or suitable is not proof of every claim. It may be a useful starting point, but the buyer should still ask which record supports the specific order line.

For a remote Kazakhstan project, returns and inspection are harder, so unresolved identity or condition questions should be closed before parts leave the supplier.

4. Request only the evidence that the line actually changes

Do not ask for one blanket certificate for the whole mixed batch. A used track group may require measured wear or clear condition photos; a new filter may require batch or date and interface dimensions; a hydraulic hose may require fitting identification and any assembly test record if specified.

A thick pack can still be weak if the relevant dimension, material or test result is absent while irrelevant documents are included. Ask the supplier to mark each document with the order line number or candidate number it supports. If that link is missing, say so and ask for a corrected document index.

5. Move unresolved questions into dated written supply terms

Before paying, ask the supplier for a dated written quotation or order confirmation that covers the specific batch. It should state the supplied condition for each line, the candidate number status, and which fitment points remain subject to inspection after arrival.

Unresolved questions are procurement risks, not only technical notes. If the supplier cannot confirm whether a hose end is the correct thread form, write it as an open condition with the responsible party named: who measures, who compares against the removed part, and who decides acceptance using the applicable parts catalogue or machine record.

Ask for a short document index that links certificates, photos or measurement results to each order line. The aim is not a promise of immediate stock availability or delivery; it is a checkable record of what is being supplied and what is still unverified.
