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

Direct answer: the box label alone is not a match. Compare the orderable part number on the box with the part number recorded from the removed component and the applicable parts catalogue revision for the machine serial range. Do not treat a casting mark, supplier SKU, batch code or handwritten note as the service part number.

1. Start from the removed component, not the new box

A maintenance purchase usually has two separate questions: is the new part the same identity as the old part, and is it acceptable for the machine. The removed component is the first reference because it often carries a part number, casting or housing mark, and installation position.

Take clear photos of the removed part before discarding it. Photograph the label, stamped number, raised casting mark, mounting face, hose ports or wiring connector in daylight. Record the exact installation position, such as left track motor, right fan drive, main pump compensator or return filter housing.

If the removed component has no legible number, record the machine nameplate and serial number. Do not rely on the model alone.

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

These five things look similar but mean different things.

A box SKU is often the seller's stock code or warehouse number. It can match one seller's inventory but not necessarily the SANY service catalogue number.

An orderable part number is the number used in the parts catalogue or purchase order. In this article, this is the candidate number you are trying to verify.

A casting mark is a raised or stamped mark on a metal housing, bracket, block or cover. It may identify the raw casting or a base component, but it is not always the orderable service part number.

A batch code or date code is for production traceability. It can help with batch quality records later, but it does not prove that the part fits the removed component.

A documented supersession means an old number has been formally replaced by a new number. Ask for the applicable catalogue revision or a manufacturer document that shows the old-to-new relationship. Do not accept a label that only says replaces old number without a document reference or catalogue revision.

3. Check the candidate number against the applicable catalogue revision

Ask the supplier for the catalogue revision and serial range used to select the new number. The correct revision for one machine serial prefix may be wrong for another even if the model name looks the same.

The necessary evidence is normally:

• machine model and suffix;
• machine serial number;
• nameplate photo;
• old part number or old label;
• component or housing photos;
• installation position;
• applicable catalogue revision;
• documented supersession if the number changed.

Request missing evidence instead of guessing from a label. A clear photo from a supplier is useful, but a photo is not proof of perfect fitment or authenticity by itself. Keep part identity, fitment, provenance, sample results and batch acceptance separate.

If you are comparing two candidate numbers, MechLink can receive the model, serial, old filter number and filter or housing photos for candidate-number checking. It is an external commercial information-support platform, not SANY's official site, dealer or service centre.

4. Avoid the common packaging-only mistakes

Do not decide that a part is correct only because it was sold as a SANY part. The supplier statement is one piece of information, not the whole verification.

Do not decide that the part is wrong only because the old casting mark is missing from the new box. Production improvements can change casting or housing details while the orderable part number remains the same.

Do not ignore a supersession. If the catalogue revision says old number A is replaced by new number B, the old number may still be printed in older manuals. Use the revision that applies to the machine serial number and the supplier's documented interchange.

5. Procurement next step

Before accepting or returning the part, put the evidence in one short list: old number, machine serial, box orderable number, catalogue revision page or document reference, and one observation about any marking mismatch.

Then ask the supplier one direct question: which catalogue revision and serial range were used to confirm this orderable number? If the supplier cannot answer, request the missing catalogue chapter or manufacturer document before making the final acceptance decision.
