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

Do not accept the part from the box label alone. Compare the old component against the parts catalogue that applies to the machine serial number and against the old part number. A box SKU, a casting mark or a supplier statement does not by itself confirm fitment, batch quality or authenticity.

1. Start with the catalogue, not the box

The first check is to identify the orderable part number from the applicable SANY parts catalogue revision. Use the machine model with its suffix and the machine serial number. Model alone can be misleading because a suffix change or production break can change the part listed.

Ask for the catalogue revision or the document number. If the supplier only says that it will fit, ask what catalogue revision was checked and whether there is a documented supersession from the old number to the new number.

2. Separate the marks and numbers on the part and packaging

Box SKU or warehouse code

A box SKU is often a warehouse or sales identifier. It may be different from the manufacturer orderable part number. Do not treat it as fitment evidence unless the catalogue or invoice explicitly maps it to the orderable part number.

Orderable part number

This is the number you compare with the parts catalogue. On the box, it may be shown as a part number, reference number or P/N. Record it exactly.

Casting or forging mark

A number cast into the housing or bracket is not automatically the orderable part number. It may be a raw casting number, material code or component identifier. Use it as supporting evidence only.

Batch code or date code

A batch code can help trace production but does not confirm that the part is correct for the removed component. Keep batch acceptance separate from part identity and fitment.

Documented supersession

If the old number has been replaced, the catalogue or an official parts notice should show the old-to-new supersession. A label showing only the new number is not enough when the old part number is not shown.

3. Collect the missing evidence from the machine

Before accepting the new part, collect the evidence that identifies the removed component:

• machine model and suffix
• machine serial number
• old part number from the removed part or nameplate
• component or housing photos
• installation position
• applicable parts catalogue revision
• documented supersession if the old number changed

Photos are useful but not proof of every claim. A photo of a box label or a component can show what is present, not that the part is authentic, acceptable or correct.

4. Compare in a fixed order

First compare the old part number against the applicable catalogue. Then compare the new orderable part number against the same catalogue entry and any supersession. After that, compare the physical old component and new component visually.

If any number conflicts, stop and request the missing catalogue revision or supersession record. Do not guess from a label or casting mark.

5. What remains unverified

Unless you inspect the actual catalogue page or official parts notice, the following remain unverified:

• the catalogue revision that applies to your serial number
• whether the old-to-new supersession is valid for your machine
• whether the box label belongs to the component inside
• whether the part is genuine or from an approved batch

Only the responsible parties, such as the buyer or the maintenance supervisor, can decide acceptance using the applicable requirements.

6. Procurement next step

Request a written line item showing the old part number, the new orderable part number, the machine model/suffix, the serial number and the catalogue revision used. If the supplier cannot provide that, treat the match as unconfirmed.

Before payment or installation, ask for the applicable catalogue page or official supersession notice for your serial number. Keep the old part until the new part has been physically compared and accepted.

7. Parts Matching Support note

If you need parts information or procurement clarification, prepare the machine model, serial number, old part number, component/housing photos and relevant labels or records.
