Part Identification
How to Take Photos for an Excavator Parts Inquiry
A practical photo sequence for documenting old excavator parts when labels are damaged or configurations look similar.
Quick answer
Take one overall photo before removal, front, rear and side views, a straight-on close-up of every label or casting number, and detail photos of connectors, ports, shafts, mounting holes and the installed position. Use good light, keep the image sharp and send the original file. Add machine model, serial number and dimensions because photos alone may not confirm the internal specification.
Begin with context and an overall view
Photograph the component while it is still installed when safe to do so. A wider view shows the machine position, hose direction, bracket orientation and nearby components that may not be obvious after removal.
After removal, photograph the complete part from several sides against a clear background. Do not submit only a close-up that hides the part family.
- Installed-position overview
- Front, rear and both side views
- Orientation of hoses and wiring
- Complete assembly including attached accessories
Make labels and interfaces readable
Hold the camera square to the label and move the light source to avoid glare. Take one close image and one wider image showing where the label belongs on the component.
For electrical parts show the connector face and pin count. For hydraulic parts show every port, flange, shaft and regulator. For undercarriage and wear parts show bolt patterns, profiles and measured dimensions.
- Every label, stamp and casting mark
- Plug shape, pins and wire colors
- Hydraulic ports and hose positions
- Shaft, spline, flange and mounting holes
- Ruler or caliper in the measurement photo
Organize photos so they cannot be mixed
Use the RFQ line number at the beginning of every filename, followed by the view, such as A03-nameplate or A03-connector. Keep original-resolution files available when small characters must be checked.
Do not add arrows or text over a label. Send marked-up copies separately and keep the original photo unchanged as technical evidence.
- One permanent ID per requested item
- Original and annotated copies separated
- Typed measurements with units
- Machine plate photographed separately
- Unclear numbers identified as uncertain
Photo requirements by part type
| Part type | Essential views | Extra data |
|---|---|---|
| Pump, motor or valve | Nameplate, ports, shaft and regulator | Machine serial and failure symptom |
| Sensor or solenoid | Label, connector face and installed position | Voltage and fault code |
| Engine component | Old number, casting and mounting area | Engine model and serial |
| Undercarriage part | Profile, flange, bolt pattern and wear | Dimensions, shoe width or link data |
| Seal kit or cylinder | Cylinder identity and installed position | Rod, bore or cylinder reference |
Buyer checklist before requesting a quote
- Machine and part are safely photographed
- Overall and installed-position images are included
- Every label is sharp and glare-free
- Interfaces and mounting details are visible
- Dimensions show the tool and unit
- Filenames match the RFQ line IDs
Frequently asked questions
Are smartphone photos acceptable?
Yes, if they are focused, well lit and sent at sufficient resolution for labels and details to be read.
Can one nameplate photo identify the complete part?
It is the best starting point, but physical configuration and machine data may still be required.
Why photograph the part before removal?
The installed view preserves orientation and connection information that can be lost after dismantling.
