BOOM ROTATION SENSOR ASSEMBLY - X23JP - 
X700AJ

1.

Assemble the end couplings (p/n-26741500)
using the hex galvanized screws (p/n-BV013000) 
to the extension pipe (p/n-06745900).

Figure 4-26.   

2.

Locate the rotation sensor (encoder) (p/n-
0660400) and encoder coupling (p/n-26741500).

Figure 4-27.   

3.

Mount the rotation sensor (encoder) to the
crossmember under the turntable bearing using 
3 - 6 x 12M screws with threadlocker. Connect
the rotation sensor electrical connector to the
connector coming from the electrical box.

See Figure 4-28.

Figure 4-28.   

4.

Route the rotation sensor electrical cable inside
the frame as shown below.

Figure 4-29.   

5.

Install a coupling onto the rotation sensor shaft
using 1 - 3x12M screw (p/n-BV013000).

Figure 4-30.   

6.

Install the protective cover over the rotation sen-
sor assembly using 3-6x16M TE screws and
washers. Install cover with the open slot facing
the engine end of the machine. 

See Figure 4-31.
