Crack Testing

Every camshaft and crankshaft brought to Micro Motor Engineering undergoes a thorough and detailed magnetic particle crack testing procedure. This allows us to detect any cracks, especially those invisible to the naked eye, on the shafts. If we find a crack of a serious nature, the shaft is immediately scrapped. Any shafts requiring hardening are subcontracted out and when returned are again re-examined in case any other cracking has occurred. Once the shafts pass the crack test they are polished to finish size. A hardness test is carried out on every journal, and all radii are checked against OEM specifications. Serious engine failure can result in the event of these procedures not being correctly executed, costing valuable downtime and loss of revenue. Factors such as these are foremost in our minds whilst working on our clients’ engines.
