11. Remove the external retaining ring from the bob shaft beneath the lower
bearing.
This retaining ring is intended for one use only. It must be discarded and
replaced after removing it from the shaft.
12. Gently pull the bob shaft (with the transducer still attached) out of the
bearing guide. The lower bearing will slide off the shaft as you do this.
13. When the bob shaft is completely out of the bearing guide, remove the
upper bearing.
14. Slide a new bearing onto the shaft to replace the upper bearing.
The oils from your skin can damage bearings. Always wear gloves
when handling them.
15. Insert the bob shaft back into the bearing guide. Push the transducer
down onto the bearing guide so that the bearing seats in the available
space.
16. Place a new bearing onto the bottom of the bob shaft and push it up into
the lower portion of the bearing guide.
17. Secure the lower bearing in place with a new external retaining ring.
18. Screw the upper magnet assembly onto the bottom of the bob shaft (for
