3. Apply dial gauge and set scale to "0."
4. Measure distance b from the measurement point to the middle
of the key profile.
 Heed force for lifting the universal joint shaft: max. 1.5 x
weight of the universal joint shaft.
5. Lift the universal joint shaft and read the measured value from
the dial gauge.
6. Calculate deflection ratio K:
