Secondary Boom Angle Sensor
The secondary boom angle sensor is used to limit
the angle of the primary boom relative to the angle
of the secondary boom and gravity.
How to Replace the Secondary
Boom Angle Sensor
Note: Perform this procedure with the machine on a
firm, level surface with the boom in the stowed
position.
1
Locate the secondary boom angle sensor on
the turntable riser bulkhead at the ground
controls side of the machine.
2
Disconnect the electrical connector from the
sensor. Remove any tie wraps securing the
wiring.
3
Remove the angle sensor cover retaining
fastener. Remove the cover.
4
Remove the angle sensor mounting bracket
retaining fasteners.
5
Remove the angle sensor and bracket
assembly. Do not lose the two springs or the
hex-shaped key.
6
Remove the sensor retaining fasteners from
the mounting bracket. Remove the angle
sensor.
Note: Note the sensor orientation on the bracket
during removal so the new sensor will be installed in
the same position.
7
Install the new angle sensor onto the mounting
bracket.
8
Install one spring, removed in step 5, into the
hex-shaped hole in the angle sensor. Install
the other spring into the hex-shaped hole in the
center of the boom pivot pin.
