How to Check a Part Number on the Box Against the Removed Component

You cannot confirm a match from the box label alone. The box may show a warehouse SKU, an orderable part number, a batch code, or a superseded number. You need to compare the number on the removed component against the orderable part number in the applicable parts catalogue revision for your machine serial number. If any of those are missing, ask for them before accepting or installing the part.

1. Start with the removed component, not the box

Record the old part markings

Before returning or scrapping the removed component, record every visible marking. Look for a separate nameplate, an engraved or printed part number, a cast-in number, and any date or batch code. Photograph the complete component, the mounting face, ports, connector orientation and any housing numbers. Do not rely on one number.

Record the box and label details

Record the box SKU, the orderable part number if shown, the supplier's label reference, any batch or date code and the catalogue revision or supersession line. A box SKU is often a warehouse code, not the machine part number. A batch code is for traceability; it does not confirm fitment.

2. Compare the right type of number

Orderable part number

This is the number normally used in the parts catalogue and purchase order. It is the strongest candidate for a comparison. Compare it with the old part number from the nameplate or engraved marking.

Casting or mould mark

A cast-in number on a housing, bracket or casing may be a raw casting identifier. It can be different from the service part number and may be shared by several finished part numbers. Do not treat it as proof by itself.

Documented supersession

If the box number differs from the old part number, the old number may have been superseded. Supersession should be confirmed in the applicable catalogue revision or a manufacturer document. A verbal statement or a supplier label alone is not enough.

Batch code

A batch or date code supports production traceability. It does not replace a part number comparison.

3. Confirm fitment from the applicable catalogue revision

Evidence to request

Request the model and suffix, machine serial number, old part number, component or housing photos, installation position and the applicable catalogue revision. Model alone never confirms fitment. A photo of the box also does not prove the part inside is correct or authentic.

Catalogue revision

Ask which catalogue revision was used for the candidate number. If the supplier cannot state the catalogue revision or show the cross-reference, treat the match as unconfirmed. Do not guess from a label.

4. If the numbers do not match

Separate the checks

Keep part identity, fitment, provenance, batch quality and batch acceptance separate. A supplier statement or photo is not proof of every claim. If the numbers do not match, ask for documented supersession or the correct part. Do not install the part. Only the responsible parties can decide acceptance using the applicable requirements.

5. Procurement next step

What to prepare for a candidate-number check

Prepare the model, serial number, old part number and component or housing photos, plus any relevant labels or records. This is more useful than a single box label photo. MechLink can receive the model, serial, old part number and component or housing photos for candidate-number checking. It is an independent commercial information service for this market, not a SANY official contact, and it does not guarantee authenticity, fitment, stock, price or delivery.
