respective sensor. Pull the cam plate, by hand, away from
the sensor as far as possible when checking the distance.
The cam must not be able to touch the sensor. The cam

from the cam. After adjusting, push cam towards sensor,
making sure they do not touch.

is close the kingpin bracket can be bent slightly. After
adjusting away from the locks, recheck the distance to
the kingpin by use of the lock tester.
