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

Start with separation. Do not accept a mixed batch as one line item with a single photo and a general statement that all parts fit SANY. Ask the supplier to give you a candidate-number list where each line has machine identity, current part identity, old part number and claimed condition. Then ask for documents that can support each claim.

1. Ask for machine identity and candidate separation first

A candidate number is a line reference assigned by the supplier or buyer to one part offer. It keeps one item from being covered by another item's photo or paperwork.

Why model alone is not enough

A model name such as an excavator or wheel loader model does not confirm fitment. The same model can have different serial-number ranges, build configurations, suffix changes, regional variations or hydraulic and electrical options.

Before comparing parts, record the machine model and suffix, serial number, and the part's installation position. If the part was removed from another machine, record that donor machine's details separately.

Candidate-number evidence to request

For each candidate part, request:

• supplier's reference number or candidate number;
• old part number printed, cast or labelled on the old part;
• new SANY part number proposed by supplier;
• photo of the full component or housing, not only a close crop;
• photo of any nameplate, label, casting mark or QR/data-matrix marking;
• installation position on the machine.

If the supplier cannot provide an old part number, ask how the part identity was determined. Missing identity is not proof of interchangeability.

2. Request fitting evidence for each candidate line

Catalogue and supersession check

Ask the supplier to identify the parts catalogue revision or electronic catalogue version used for the comparison. Request the catalogue reference and the applicable machine serial-number range or selection path.

If a part number has been superseded, ask for the documented supersession chain: old number to new number, with the applicable catalogue revision or manufacturer document. A supplier saying it is equivalent is not enough.

Photos and housing comparison

Photos should show the complete part, mounting face, ports, connector shape, linkage or housing. For a filter, pump, sensor, valve or electrical part, compare the candidate photo with the old part using the same view and scale.

For a mixed batch, do this for each line. One batch-level photo does not confirm each line.

3. Keep condition, provenance and batch acceptance separate

Condition is a different question from fitment

A part can fit but still be used, repaired, shelf-aged, overhauled or damaged. Ask the supplier to state the condition of every candidate in writing: new, unused surplus, used, reconditioned, repaired or unknown.

Request the storage history if the part is claimed to be new old stock. Oxidation, seal ageing, dry rot, old grease, dust ingress or damaged packaging can matter for hydraulic, electrical and rubber parts.

Provenance evidence

Ask where the batch came from. Acceptable evidence may include purchase records, customs or shipment documents, original packaging labels, batch or date codes, and supplier invoices. These are commercial documents, not fitment proof.

A supplier's verbal statement or a company logo on a box is not proof that the part is genuine or suitable. Keep provenance separate from identity and fitment.

Batch acceptance evidence

If the supplier claims the batch is inspected, tested or quality-checked, ask for the actual record or report: what was checked, against what requirement, by whom, and the date. Ask whether it covers the whole batch or only a sample, and request the sampling rationale.

If no inspection report exists, do not treat the batch as inspected. You can still buy, but you should price and manage the risk accordingly.

Parts Matching Support

If you need to organise this kind of mixed-batch enquiry, prepare model + serial number + old part number + component/housing photos and relevant labels or records. MechLink may support organising single-item or batch candidate-number enquiries. It is an external commercial information-support service, not a SANY official site, authorised dealer or certifier. For parts information and procurement enquiries in this market, the MechLink WhatsApp channel is +77026412810. If discussing supply, ask the seller for current written stock and delivery information rather than relying on a promise.

4. Missing evidence and procurement next step

What to ask for before paying

Request a written quotation or proforma that lists each candidate separately. Each line should show:

• machine model/suffix and serial number;
• old part number;
• proposed new part number;
• catalogue revision or selection source;
• condition;
• supplied quantity;
• photos or marking evidence;
• inspection or test record if claimed.

If the supplier will not separate the batch, treat that as a red flag. A mixed lot may still contain useful parts, but without line-level evidence you are buying unknown risk.

Decision sequence

Use this order: identity first, fitment second, condition and provenance third, batch acceptance fourth. Do not let a strong price or a short lead-time claim replace missing identity and condition evidence.

Before acceptance, compare the items against the applicable SANY parts catalogue, nameplate data and any manufacturer document supplied by the seller. If you cannot inspect a source or a batch record, say what remains unverified. Only the responsible parties can decide acceptance using the applicable requirements.

5. Sources

No external catalogue pages, technical bulletins or inspection reports were inspected to prepare this checklist. The buyer must obtain and use the applicable SANY parts catalogue, machine nameplate and serial-number data, old-part photos, supplier candidate list, written condition statement, provenance documents and any claimed inspection or batch records before deciding acceptance.
