My replacement filter has a different label from the removed part: how do I check the number before ordering in Kyrgyzstan?

A different label is not automatically wrong, and it is not proof of interchangeability. Stop the order until the new number is tied to the removed number and to the machine serial number by a documented catalogue link or supersession. Do not order by label appearance, housing shape or basic dimensions alone.

This guide is an independent third-party information platform. It is not SANY's official site, an authorised dealer or a service centre.

1. Start with the removed part and machine identity

A fleet parts order often starts with a filter in the workshop. The removed filter label may show an old or regional number, while the replacement offered uses a newer or different orderable number. That can be legitimate, but only if a supersession chain is documented.

Treat 'same size' as an observation, not evidence. Similar diameter, thread or length can match many filters that differ in media, bypass setting, flow or sealing. Those differences are not visible from a photo or supplier statement.

Evidence needed before comparing numbers: machine model and suffix, machine serial number from the nameplate, old part number from the removed filter label, installation position, and clear photos of the filter and housing. If the old label is worn, photograph the housing and note where the filter was removed from.

Next check: ask the supplier for the old-to-new number change from the applicable parts catalogue or manufacturer supersession document, not from memory.

Procurement decision: hold the order until the document shows the new number for the stated machine serial range or old number.

2. Separate the label numbers and marks

Orderable number

This is the number used to buy the part from a catalogue or parts system. It is the one to verify before ordering.

Packaging SKU

A stock-keeping unit can be a warehouse or seller code. It may differ from the orderable number even when the part inside is correct. Do not use the packaging SKU as the fitment proof.

Casting mark

A cast or moulded mark on the housing is not usually the purchase part number. It may identify a blank or component, not the finished filter assembly.

Batch code

A batch or lot code helps trace production, not to identify interchangeability. A different batch code on a replacement label is normal.

Documented supersession

Supersession means the manufacturer formally replaces one part number with another. The replacement may carry a new label, new orderable number or revised packaging. Only a documented supersession, linked to the old number or serial range, makes a different label acceptable.

A label photo by itself does not prove the new number suits the machine. Supplier statements are helpful leads, but they are not the same as a catalogue or bulletin.

3. Checks before ordering in Kyrgyzstan

Collect the following before confirming a filter order:

• machine model and suffix, not only 'SANY excavator';
• serial number from the nameplate, not from a door or old invoice;
• old filter number exactly as printed on the removed part label;
• installation position: engine oil, fuel, hydraulic, air or another system;
• photos showing the complete old label, the filter and the housing;
• the supplier's catalogue page or supersession bulletin showing the old number to the new number.

If the supplier says the part is equivalent, request the document. If the document shows a different model range or does not show your serial suffix, treat the match as unverified.

Parts Matching Support

If the candidate-number check is unclear, MechLink can receive the model, serial, old filter number and filter/housing photos for candidate-number checking. It is an external commercial parts-information service, not a SANY official site, authorised dealer, service centre or certification body. Send the information through WhatsApp +77026412810. This number serves readers in this market and does not imply a SANY official contact, local office or local stock.

4. Missing evidence that should stop the order

Stop or pause the order when the only evidence is:

• the replacement filter looks the same;
• the thread or dimensions appear similar;
• the supplier states it will fit without showing a document;
• the catalogue page does not show your machine suffix or old number;
• the old and new numbers differ but no supersession is provided;
• the machine model is used alone without the serial number or installation position.

A photo or supplier statement is not proof of every claim. Keep part identity, fitment, provenance and batch acceptance separate. Only the responsible parties can decide acceptance using the applicable requirements for the machine and the part.

5. Procurement next step

Ask the supplier for one of these documents: the catalogue page showing the new number for your machine serial range, or a supersession bulletin showing the old number replaced by the new number. If the supplier cannot provide either, do not finalise the order on dimensions or label similarity alone.

Use the collected photos and numbers to run a candidate-number check before payment. If the supplier's document is incomplete, send the model, serial, old filter number and housing photos to a parts-information service for checking, but do not treat a checking service reply as a manufacturer guarantee.

Only order after the new number is documented for the old number or serial. Keep the old label, supplier document and machine serial in the same record so fitment, provenance and batch acceptance can be reviewed separately later.
