How to Identify a Swing Motor
The tag plate does most of the work. Send what you can and we confirm the rest before quoting.
| What to send | Where to find it | Why it matters |
|---|---|---|
| Machine make, model and serial number | The manufacturer's plate on the machine. | This is what we check against the product reference guide, so it is needed on every enquiry. |
| Tag plate photograph | The manufacturer's tag on the swing motor, or on the swing reducer if that is the unit you need. | A legible tag identifies the unit directly, including the manufacturer's part number. |
| Swing motor, swing reducer or both | Whether the motor, the gearbox beneath it, or the complete assembly is being replaced. | Decides which unit is quoted. Both are listed on every make page. |
Scroll the table sideways to see every column.
Our hydraulics team checks every enquiry against the product reference guide before a swing motor is quoted, so a photograph of the tag and the serial number is usually enough.
