1.2.2.2 Valve Lash Gauging Application
In a Valve Lash application a bolt and a nut should be rotated and locked to each other to achieve a
specific valve lash. This can be done with a special coaxial spindle, e.g. QMX 42-2RT.
It is easy to create a program that operates the two spindles in a controlled way to make up perfectly
adjusted valve lash.
