How do I check whether a SANY part number on the box matches the component removed from my machine?

You cannot confirm that the boxed part is correct by reading the box label alone. Use a three-way check: the orderable part number or box SKU, the old part number or marking on the removed component, and the applicable parts catalogue revision for your machine serial number. Then compare physical fitment features such as flange, bore, thread, mounting holes, port orientation or housing shape. Model alone never confirms fitment, batch quality or authenticity.

1. Start with the serial number and applicable catalogue revision

A SANY machine model can have suffixes, production breaks or option differences that change the required component. Ask for the correct catalogue revision before trusting a superseded or replacement number.

Model/suffix and serial number

Record the full model and suffix from the machine nameplate, and the serial number. The serial is the key that links the machine to the correct catalogue section. Do not stop at the model name on the side panel.

Catalogue revision and supersession

A parts catalogue revision may change an old part number to a new orderable part number. If the box number differs from the old part number, ask whether there is a documented supersession. The supplier should show the supersession path from your old number to the box orderable number in the applicable catalogue revision, not simply state that it will fit.

2. Separate box SKU, orderable part number, casting mark and batch code

Box labels can contain several numbers. Treat them as different evidence types.

Box SKU and orderable part number

The box SKU may be a warehouse or sales code. The orderable part number is the catalogue number used to buy the item. Check that the orderable part number is the one shown against your serial number in the parts catalogue. A box SKU alone is not enough.

Casting or forging mark

A cast or forged housing may show a raw casting number. That number can look like a part number but usually identifies the blank or casting, not the finished orderable assembly. Do not use a casting mark as proof that the component matches the removed item unless the catalogue explicitly lists it.

Batch code and date code

A batch code or date code can support traceability and age checking, but it does not confirm fitment. Keep it separate from identity and applicability checks.

3. Use the removed component as evidence

The component that came off the machine is one of the strongest clues, but only if you record it before discarding it.

Old part number from label or stamping

Look for the old part number on the removed component label, tag, stamping or engraving. Write it down exactly, including dashes or spaces. If the label is damaged, take clear photos before cleaning too aggressively.

Physical comparison features

Compare the mounting face, hole centres, thread size, port positions, connector orientation, shaft or spline shape, sensor boss, and any locating pin or dowel. A physically different part can still have a valid box number for a different serial range.

4. Photo evidence and what it can and cannot prove

Photos are useful for review, but they are not a certificate of authenticity or fitment.

Useful photos

Photograph the machine nameplate, serial number, removed component from several angles, the old label or stamping, the box label, and the new part next to the old part. Include a ruler or tape in the frame only if safe and practical.

What a photo does not prove

A photo can show that two parts look similar. It cannot prove batch quality, material grade, internal clearance, pressure rating or whether the part was supplied through an authorised channel. Keep identity, fitment, provenance, sample results and batch acceptance as separate questions.

5. Missing evidence before you accept or reject the part

If the box number, old part number and serial-specific catalogue number do not all line up, do not guess.

Simple decision sequence

First, confirm the serial-specific catalogue part number. Second, compare it with the box orderable part number. Third, compare it with the old part number or a documented supersession. Fourth, confirm the physical features of the new part against the removed part. If any step is missing, request that evidence first.

Procurement next step

Ask the supplier for the applicable catalogue revision reference and the supersession path in writing. If the supplier cannot provide it, treat the fitment as unverified. The responsible party for acceptance is the person using the applicable manuals and requirements, not the label or a supplier statement alone.
