14. Remove the lower bearing (14).
For reassembling the sensor:
1. Install the bearings in reverse order.
2. The rotating transformer assembly (7) is reinstalled together with
the sensor board (9). Its (7) set screw is not fastened until in step 7,
when the power supply board has been reinstalled and the gap
adjusted.
3. When assembling, push the transformer (7) as far up as possible
towards the shaft tunnel.
4. Reassemble the spacer screws (8), the power supply board (4), and
tighten the nuts (5).
5. For adjusting the gap, place a 0.4 mm (0.016 in.) feeler gauge
between ferrite coils (parts 4 and 7) (preferably use a 30 mm wide
feeler gauge).
6. Place a screwdriver tip into the slot between the top end of rotating
transformer assembly (7) and the shaft tunnel, and pry until the air
gap between ferrite coils is 0.4 mm (0.016 in.) (use the feeler gauge
for measuring).
7. When the gap is right, carefully fasten the set screw of the rotating
transformer assembly (7).
8. Reconnect the shaft heating foil (6) and the connector for the two
white wires (3).
9. Reassemble the body cover (2) with new O-rings.
10. Tighten the three capnuts (1) and the connector nut.
NOTE
Be careful when assembling the bearings, do not drop or hit.
NOTE
Make sure that the four-pin connector (15) fits properly.
CAUTION
The ferrite coils are breakable, do not try to adjust the gap by prising
them.
CAUTION
Make sure the rotating transformer assembly rotates freely without
touching the lower part at any rotary position of the shaft.
