Do not tighten the nut with excessive force. A washer must be
used with the nut.

Part B
Part A
Note: 1 .The table below shows the tightening torques for part A and part B
nuts. In the previous examples, the nut is on the sensor head side
(part B) and hence the tightening torque for part B applies. If this nut
is in part A, the tightening torque for part A applies instead.
2 .The table below shows the value of tightening torques when using
toothed washers.
