What to ask before buying a mixed batch of SANY spare parts for a remote Kazakhstan project

What to ask before buying a mixed batch of SANY spare parts for a remote Kazakhstan project

Direct answer: Ask the supplier to convert the mixed list into line-by-line records. For each order line, request: machine/assembly identity, old part number or component photos, supplied condition, batch/lot or date reference, and only the relevant dimensions, material or test evidence for that part family. Do not accept model alone, and do not treat a thick certificate file as linked evidence unless every line maps to a document. This article is an independent editorial checklist, not SANY official guidance, dealer advice or batch acceptance testing.

1. Ask for an order-line identity before any part number debate

A mixed quotation is often a spreadsheet only: filter, seal kit, hose, track shoe. That cannot confirm fitment.

Ask the supplier to add a candidate number to each order line. A candidate number is a single identifier that connects a quoted part to one photo, one old part number, one drawing or one inspection record.

For every line, ask for:

• machine model and suffix, not only the base model;
• machine serial number or nameplate photo;
• old part number from the removed component, if available;
• component or housing casting marks or assembly labels;
• installation position or side;
• clear photos of the old or candidate part, label, hose collar or wear surface.

Model alone misses production breaks and running changes. An old part number is useful but may have been superseded. Ask the supplier to state a documented supersession in writing instead of saying 'will fit'.

2. Change the questions by part family

Not every mixed-batch line needs the same evidence. Filters, seals, hoses and undercarriage items fail in different ways.

Filters

For filters, first ask for the old filter part number and head or manifold details: thread form, gasket/seal diameter, canister diameter and length if interchange is uncertain.

If the supplier offers an aftermarket or equivalent filter, ask for a written comparison to the old or catalogue part: thread dimensions, seal face, gasket size, bypass setting and media type. A thread that screws on is not itself proof of equivalent performance.

Batch or date code matters mainly if the filters will sit in remote storage. Ask the supplier to state manufacture date or lot code in writing; do not infer shelf life from a photo.

Seals

For seals, request the old part number and the mating dimensions: groove or gland, shaft or bore size, and installation position. If the line is a seal kit, ask for a contents list tied to positions, not just 'complete kit'.

Material and hardness should be requested when the seal works in hydraulic oil, high temperature or heavy dirt. Ask for a material certificate or lot trace only if the seal is critical. For a low-risk dust seal, extra paperwork does not improve the fitment decision.

Hoses

For hoses, ask for assembly length, end fitting type, thread or seal seat style, working pressure and hose construction. A photo of a hose alone cannot show pressure rating.

For high-pressure hydraulic hoses, ask whether a pressure test record or batch trace exists and which line it belongs to. For a low-pressure return or drain line, dimensional and end-fitting confirmation may matter more than an extra certificate.

Undercarriage items

For track chain, shoes, rollers, idlers or sprockets, the machine serial range and track group are the starting point. Ask for pitch, bushing outer diameter, shoe width, bolt pattern, link count and mounting dimensions where relevant.

For high-cost undercarriage items, ask for the supplier's batch or heat/lot reference and any inspection report. But dimensional match and part-number match come first; a material certificate does not fix a wrong-pitch chain.

3. Keep condition, provenance, sample results and batch acceptance separate

A supplier's written statement 'genuine SANY' is a claim, not proof. A photograph shows only that an item existed, not that it is new, genuine, or correct for the assembly.

Ask the supplier to state per order line whether the part is new, old stock, removed, reconditioned or aftermarket. If the seller says OEM or genuine, ask for the document that links that specific batch to that claim; otherwise ask for the words 'aftermarket' or 'not confirmed' in the offer.

Batch reference should be a separate field: lot, heat, date code, carton marking or production date. That reference must appear on the document index, not only on a distant page of a PDF pack.

Sample results or test certificates are only useful when the item-to-record link is clear. The same applies to catalogue extracts. A thick document pack can still lack the one thing needed: line 4 to candidate number to document number.

4. Record unresolved questions as dated written supply terms

For a remote Kazakhstan project, a return is slower and an undocumented substitution is harder to correct. Unresolved questions should become written terms before payment.

Ask the supplier to confirm or mark 'not confirmed' for each of the following:

• fitment to the buyer's serial or assembly number;
• condition of each line;
• batch or lot reference;
• any test certificate or inspection record available before shipment and the exact line it covers;
• current written stock and delivery information.

Ask for the offer or order confirmation to be dated and in writing. A verbal or chat promise is not a supply term. You are not asking the supplier to certify every claim; you are asking which claims are supported and which remain open.

Missing evidence is a procurement issue until the responsible parties decide acceptance. Do not guess fitment from model or from similar parts.

5. Use a short checkpoint before ordering

Before accepting any line, you can hold it until the supplier provides:

• machine/assembly identity: model suffix, serial or nameplate, old part number, installation position;
• candidate number;
• supplied condition;
• batch/lot or date reference when relevant;
• the relevant dimension, material or test document for the filter, seal, hose or undercarriage item.

If a document is supplied without a line link, ask: 'Which order line and candidate number does this belong to?' If the answer is not written, the evidence pack is not complete.

Parts Matching Support

If you are dealing with many single-line or mixed-batch enquiries, a parts-matching support service may help you organise candidate-number records and photo requests. MechLink is an external commercial platform, not SANY's official website, dealer or service centre. You may send model + serial number + old part number + component/housing photos and relevant labels or records. Kazakhstan Phone / WhatsApp: +77026412810. Ask the supplier for current written stock and delivery information; do not rely on verbal availability. This support does not certify authenticity, fitment or batch quality.
