Installation
2-76 Manual # 42-02-2P24
It is critical to ensure that the sensor is installed so
that any mechanical contact between tape and sensor
head is between the steel band and the polymer sensor
guide. Adjust for a horizontal offset of 1 inch (25 mm)
between the sensor metal face and the magnetic band
so that contact between the steel side and the polymer
guide is firmly forced.
When properly installed, looking at the top of the sensor,
there will be a slight gap between the magnetic band and
the body of the sensor. Refer to the illustration below.

With the sensor guide
re-installed, the tape
should arc gently
away from the car at
the top and bottom,
forcing the steel side
of the tape firmly
against the polymer
guide.
Be certain that the
sensor head is
plumb with the
tape. Check top
and bottom to be
certain it is not out
at the bottom while
appearing correctly
offset at the top.
