Identify a part without guessing compatibility

Appearance does not prove compatibility

Two visually similar parts may differ by a dimension, connector, revision or machine application. A photograph alone is not always sufficient.

The most useful evidence

• readable OEM reference;
• machine make, model and serial number;
• data-plate photograph;
• multi-angle photographs of the part;
• dimensions and connectors;
• previous invoice, manual or catalogue when available.

State quality clearly

An offer should say whether the part is genuine, equivalent, aftermarket, remanufactured or used. This affects price, terms and service-life expectations.

The right reflex

When information is missing, flag uncertainty and request another check instead of confirming compatibility too quickly.
