1.
On the new pressure sensor cables, strip the end
of each cable and crimp pins to each stripped
cable.
Tip:
If you do not have the necessary
tools to do these operations on the cables,
another solution is to keep the old cables
connected to the connector, cut them at
mid-length and solder the new cables to
them.
2.
First, install the components in the same order
as on the picture 1 (if no pressure-relief spring,
there is no metal ring).
3.
Insert the install tool into the hole in the end
cap and tighten with the flat screwdriver to set
the pressure sensor in place. The install tool is
longer than the normal screw in order to push
the pressure sensor to the bottom of the hole.
CAUTION:
Always use the install tool to
set the pressure sensor in place. Never
directly insert the spring and screw with
the pressure sensor or you may damage
the pressure sensor.
CAUTION:
Never push the pressure
sensor from the outside with your finger
or any tool to put it into the hole. Pressure
sensors have a thin membrane that is very
fragile and pressing it will damage the
sensor. The install tool correctly place the
pressure sensor at the bottom.
4.
Remove the install tool. It is no longer needed.
5.
If you have a pressure-relief spring, put the
spring into the hole in the end cap (picture 2). If
you have no spring, only install the screw.
6.
Apply loctite on the screw thread and tighten the
screw into the end cap with the flat screwdriver
to hold the spring in place.
6.
Connect the new pressure sensor.
