810-X Bar Replacement Procedures

808-P2 SeeLevel Special Tank Truck Gauge

1. Remove the headcap and disconnect the optical fibre from its connector.
2. Disconnect the nut on the brass fitting and remove the brake line and fibre from the head.
3. Mark the tube at the point that it exits the 1” compression fitting.
4. Loosen the top of the 1” compression fitting.
5. Remove the bottom portion of the 1” compression fitting from the coupler in the tank.
6. The tube can now be CAREFULLY lifted out of the tank. The float will remain sitting on the support.
7. Measure the length of the old bar from the underside of the head to the underside of the endcap attached to the bottom of the tube. Also measure the distance between  the underside of the head to the mark you made in step 3. This measurement will be used again when reinstalling the new bar.
8. Cut the new bar 1/8” less than the old bar. Use a hacksaw only, NOT a cutoff saw! After cutting the bar make sure the electronic traces on the circuit board are not  touching. Do this by using a small flat head screwdriver to clean out the potting material around the circuit board. Then with a flat edged knife trim the end of the circuit  board making sure they are not touching. (If possible test the bar on top of the tank to make sure all the readings are there.)
9. Place the new compression fitting on the bar, (thread down) slide it towards the head, and tape it in place so that it can’t slide.
10. Install the endcap using the Loctite method as per Technical Services Bulletin #17.
11. Observe the serial number of the old bar (the label can be found inside the head). If the serial number starts out with “810S” then you have to change out the float as  ell.
12. Retrieve and replace the float. Note that the cone shape of the new float should face up.
13. Remove the tape holding the compression fitting and apply some anti-seize compound to the threads then install the new tube making certain that the end goes through  the hole in the float and into the support.
14. Tighten the bottom portion of the 1” compression fitting into the coupler.
15. Position the tube so that the space between the underside of the head and the top portion of the compression fitting is the same as you measured in step 7.
16. Tighten the top of the 1” compression fitting.
17. Replace the fibre into the head and tighten the brass nut. Ensure that the head is vented as per Technical Services Bulletin #18. The head O-ring had grease applied to it  before it was shipped but it may be helpful to do it again. Use any common O-ring lubricant. Replace the headcap.
18. Have an assistant raise the float while watching the gauge display to make sure the system is functioning.
19. The reinstallation is now complete. Note that the bottom reading MAY be slightly different from the previous one. Make sure that the operator is aware of any change.
