Installing the Nose Cone and Transducer in the Shaft
The shaft and motor hardware service kit contains new seals. You should use the new parts from the kit instead of reusing the seals you removed with the nose cone and transducer.
NOTE:
If you are performing this procedure because you are removing the transducer completely, you should complete only the first step.
-
Place the 25 mm (1 in.) O-ring on the recessed nut from the shaft and motor hardware service kit.
-
With the O-ring facing the transducer, feed the replacement transducer cable through the recessed nut
and the hole 
in the front of the shaft base, but do not feed it up through the shaft.
-
After you have fed all but approximately 60 cm (2 ft.) of the transducer cable through the hole in the shaft base, feed the transducer cable up through the shaft.
