What Should I Ask Before Buying a Mixed Batch of SANY Spare Parts for a Remote Kazakhstan Project?

Ask for a written line-item list that ties each spare part to one machine or assembly identity, a candidate number, the old or current part number, supplied condition, batch or lot reference, and only the specific dimension, material or test record that the part type actually needs. Do not accept a general statement that the parts are SANY parts or that the model matches.

Why this matters A mixed batch often contains filters, seals, hoses and undercarriage items in one box. Model alone does not confirm fitment, batch quality, authenticity or condition. A thick document pack can look complete but still fail if no record is linked to a specific line item.

一、Start with line-item identity, not the model

1.1 Assign a candidate number to each line

Ask the supplier to give every line a candidate number or order-line reference. That number should connect the quote line, the physical part, the photo and the record. Without this, a batch-level certificate cannot support a specific part.

1.2 Capture the old part number, serial number and assembly position

For each part, request:

• the old part number from the removed component if available;
• the machine serial number, not only the model or suffix;
• the assembly position, such as engine oil filter, swing motor seal, boom hydraulic hose, track roller;
• component or housing photos before removal if possible;
• the applicable catalogue revision only when the supplier is using it to confirm interchange.

If the old part number is missing, ask for photos and placement measurements instead of guessing.

二、Ask different evidence for filters, seals, hoses and undercarriage items

2.1 Filters: confirm the filter type and batch label

Ask for the filter part number, filter type, intended circuit or housing, and the batch or production label data. A photo of the label is supporting identity, but it is not proof that the batch is authentic. Request the supplier to state in writing that the supplied batch markers match the line item.

2.2 Seals: confirm material and dimensions when critical

Ask for the claimed material grade, the relevant dimensions or the seal kit part number, and the position where the seal set is used. For oil seals in an assembly, a supplier statement that it is suitable for SANY is not enough. Request the catalogue reference or a dimensioned drawing if fitment is not obvious.

2.3 Hoses: confirm pressure circuit, end type and length

For hydraulic or pilot hoses, ask for the hose working pressure class, end fitting type, nominal diameter and length, or the supplier part number matched to the assembly position. If the hose is for a remote repair, request a photo of the existing hose tag or ends rather than only the machine model.

2.4 Undercarriage items: confirm condition, measurement and batch reference

For new undercarriage parts, ask for the part number and any heat or batch reference claimed by the maker. For used or refurbished track links, rollers or idlers, ask whether the item is new or used, the claimed remaining wear or measured dimensions, and photos of the wear surfaces. If no measurement exists, mark that line as unverified.

2.5 Do not request the same evidence for every line

A filter often needs a legible batch label and part number. A hydraulic hose needs pressure and end identification. A used undercarriage part needs condition and dimension evidence. A thick pack is useful only when each record points to a candidate number. If the pack has many generic certificates but no item-to-record link, treat the missing link as an open risk.

三、Keep identity, fitment, provenance, sample results and batch acceptance separate

Do not let one document cover all claims.

• Identity: the part number, marking, label or candidate number.
• Fitment: machine serial, assembly position, old part number and catalogue revision.
• Provenance: written statement of new, used, refurbished, and the supply source or chain.
• Sample results: test or measurement results for a defined sample or batch only.
• Batch acceptance: the buyer's or project's written acceptance criteria, not this guide's approval.

A photo can support identity or condition, but it cannot prove authenticity, material specification, pressure rating or test results. A supplier statement can record a claim, but it is not an inspection result.

四、Ask for missing evidence in dated written supply terms

Before ordering, ask the supplier to confirm in writing:

• the line-by-line description with candidate numbers;
• new or used condition for every line;
• the part numbers and batch or lot references where relevant;
• the specific documents supplied for that line, such as label photos, dimension sheets, pressure class markings or supplier statements;
• any unresolved questions marked clearly, for example missing old part number, missing batch label or unmeasured used undercarriage item.

Request current written stock and delivery information as part of the quotation or order confirmation, but do not treat an estimate as a promise. Only the responsible parties can decide acceptance using the applicable project or manufacturer requirements.

五、Parts Matching Support

If you have a mixed list and need to organise candidate numbers and photos, MechLink, an external commercial parts-information service, can help structure the enquiry. Provide model, serial number, old part number and component/housing photos plus any labels or batch records. It does not certify fitment, authenticity or acceptance.

No external SANY catalogue pages, manufacturer test certificates, supplier batch reports or standards were available for inspection for this article. The checks refer only to the buyer's machine records, the supplier's written quote and order documents, and the part labels or photos that the buyer should request. All part numbers, catalogue revisions, dimensions, material grades, batch numbers and test reports must be supplied and verified by the responsible parties.
