  1. Press the get together into a ring gage of the legitimate size as given in the even information.
  2. Gage the drag with the predefined plug gages of the legitimate size, as given in the tables of measurements.
  • The locking plug is pivoted to protect lockup when the grip is worked at low breaking point shaft and is mounted in a high cutoff lodging sufficiently able to appropriately measure
