Only OEM approved replacement parts are used throughout final assembly. Our staff are equipped with specialised tools and work in close conjunction with workshop manuals and procedures. Details such as bearing crush and draw, as well as piston height clearances and sizes, are recorded on the assembly sheets. All measuring equipment and tools used for tightening are regularly calibrated and certified to ensure that each engine leaving Micro Motor Engineering performs precisely as it was designed for and renders trouble-free service. This is in keeping with the strict ISO 9002 standards that run throughout our factory.
