The following detail a selection of the metrology techniques and equipment used by KMP throughout the development and quality control process.


The CMM is used to measure the geometry of our parts using various probes. This machine can measure down to a resolution of 1 micron and is used to measure many parts including pistons, ring gears, crankshafts, camshafts and rollers etc.

This is an example of a KMP Brand Piston Drawing. In order to be approved, this drawing has been compared to OEM. The OEM Piston was measured using the CMM (as seen in the previous slide) and the recorded measurements will have been compared to the drawing. Any corrections needed will have been identified and altered in order to ensure that the drawing is representative of the OEM piston, at which point the drawing can be approved. After approval, a production sample will be manufactured and analysed by the Quality Department to ensure that the sample is in line with the approved drawing on record. Both the approved drawing and sample are now held in our library as a point of reference.

The digital microscope can zoom up to 160x and is invaluable in the measurement of bearing material thickness, coating analysis (piston rings) and failure/crack analysis.

The shadowgraph is used to analyse part profiles and is beneficial in the measurement of valve angles and piston ring profiles.


Ensuring the tension is correct when developing a piston ring is essential within the drawing approval procedure. This allows us to supply piston rings that will function in the same way as OEM.

In order to ensure measurements are taken on a flat surface, KMP use a Granite Surface Plate which allows quick accurate readings when using the digital vernier height gauge. This is most used when completing delivery checks.

To measure the journal diameters of crankshafts and camshafts, multiple readings are taken at different points using a digital micrometer. For an accurate reading, an average is taken of the points recorded. The digital micrometer has a resolution of 1 micron. An engine hoist is used to manoeuvre the larger components to ensure all KMP products are measured.
crankshaft analysis


All hardened components are tested using either a Leeb Hardness Tester or the Rockwell Hardness Tester shown on the left. Once again, multiple measurements are taken in order to ensure the part has been hardened in the appropriate places. The hardness is commonly measured on valves, piston pins, cam followers, crankshaft/camshaft journals, valve seats etc.

Smaller engine parts are measured using Digital Micrometers which have a resolution of 1 micron. KMP have a large selection of this equipment.

Rubber hardness is also an important consideration to make in the development of both gaskets and seals. Rubber hardness is measured using a Durometer.

XRF Analyser

The latest addition to the KMP Quality Department is our new XRF Analyser, which determines the elemental composition of the material of a part through non-destructive spectroscopy.
  • All OEM parts can be tested using the XRF Analyser in order to the material specification to be identified. This information can be used in development to ensure that our parts will perform to the same standard as the OEM material.
  • Any KMP part failures can be fully analysed using the XRF Analyser to ensure that we maintain our high standards throughout our parts.
