Identifying a Part Without a Reference

Photograph it flat

On plain paper, with a ruler in the frame, shot straight down. An angled photo cannot be measured, and outline is what identifies most flat parts.

Photograph it fitted

One picture of the part in place on the machine. Parts that look identical often mount differently, and the mounting is what fixes which one you need.

Look everywhere for markings

The part itself, the old box, the machine plate and any maintenance records. A stamped reference removes almost all guesswork.

Give the machine data

Builder, model, diameter, gauge, feeder count. For electrical parts add the circuit voltage. For needles add the position, cylinder or dial.

Confirm with a sample before the full quantity

Where a machine set is a large order, confirming against one piece first is cheaper than confirming against a shipment.
