  1. You mean the valve housing? There\'s a handle for that, HS5777 listed in the old B-2-11. I see no mention of a sling anywhere, or any lone procedure for removing the pump housing by itself.
  2. There is a whole lavatory that you could put on cargo aircraft referred to above, NSN 4510-01-080-5922. But I doubt that is what you are looking for. [img size=552]http://www.herkybirds.com/images/fbfiles/images/portable_lav.JPG
  3. What they need to do is modify the level trasmitter so it doesn\'t come on unless it\'s 4 quarts low, or just disable it. There i go with that crazy talk again...
  4. You know, back that long ago in Germany, crew chiefs took the Radome off for us, so I don\'t remember what was used. We had a stand/dolly at Pope, the \'Dorf and Ramstein.
  5. I have the drawing for the regular C130 radome sling. Maybe with a little modification, you can make it fit yours. Just let me know, I\'ll need a good email address, so message me.
  6. It appears the problem may be fixed. The guys at the Rock found a loose ground lug coming off of Pin A on the small plug on the N-1 compass ME-1 amp. Without the ground, the 26 VAC that comes from the ECA (shown in the side left of the previous diagram) that feeds pin B of that same connector on the ME-1 amp, won\'t supply voltage across the synchro to send a compass signal to the RADAR. Hoo-rah to thorough technicians.
  7. I\'ll buy you a Bit the next time I see you.
  8. Anyone know how many times they did the C130 landing and take off on the Forrestal and if there was any mechanical assistance?
  9. I never went on a night mission in Greece with the APQ122-V8, and I sure wouldn\'t with the 241. As usual, my hat\'s off to the Talon Drivers. We didn\'t have NVG\'s back then either.
  10. NSN is 5985-00-757-8981, p/n 5-88154-4. They are XB3, and will make some nice beer cans. Wow, I was impressed. They must be about 12 feet long, and have a mount for the coupler inside. AC-130U? Don\'t they have the HF antenna rods in the L.E. of the tail like the H3s?
  11. I would call that a drastic hardware change, with the addition of a vertical antenna drive section.
  12. I\'d be more than happy to take one off you hands. They won\'t be of any good to anyone else.
  13. I just don\'t see how you can do TF with an antenna that only sweeps side to side, and not that fast either, unless they changed some hardware along with the software on the 241.
  14. Ice and water don\'t pose much of a problem for X-band frequencies, 10GHz range. The reason the glycol tanks were needed for the AWADS and Talon 1 was the Ka-band PGM, 34GHz.
  15. Send me a good e-mail address. Electricians are fairies? Hmmmmmm, I won\'t ask what nav/RADAR techs are then. All I know is we do with higher frequency.
  16. You want main and/or essential, and for what year model?
  17. Sorry natops, but it has to be a wiring problem on the Nav display side. I\'m sure they swapped the power supply, they just didn\'t say. You are correct that it is the only non-common component, but for the most part, if an APN59 component is bad, it stays bad 100% of the time. Pretty much over the years, I\'ve found that bad wire connections are responsible for a very large majority of intermittent problems like this. In the diagram, you\'ve highlighted only one synchro input. We don\'t know if the pilot\'s works in STAB or REL, or at all. They can\'t seem to get the aircrew to help, and we can\'t here at Moody either. Hell, it\'s a miracle if they do a requested in-flight op check the first or second flight. The only thing I can suggest is taking apart all the connectors where the wires run. Only problem with that is that you are screwing around with wires that were soldered 40 some odd years ago, and the possibility of breaking more is great. Seeing the returns will tell you the antenna is rotating as well. But, the HDG MKR flash is controlled by a microswitch on a huge cam. If it flashes, the antenna has to be rotating.

I\'ve been a civilian for many years. I have my info in my profile. APN59 was MY bench at my first base. They usually chained a big guy to that mock-up so moving the antenna and R/T was no problem.
  19. Yup, 6 \'85 models and one \'89. One of them might be AMP\'d.
  20. South Africa is paying 830 Million Euro for 8 aircraft. That\'s 100 million a piece, which converts to about $180 million for us. Hmmm, that\'s a J-model and a couple C27 Spartans thrown in. Anyone know what guns they are putting on the C27 Gunship, BTW?
  21. Oh if it were that easy TOPS. The heading reference comes from the compass and goes thru the ECA, antenna J-Box, antenna, RADAR J-box, Control panel for the Nav\'s, power supply, then the scope. Any one of the X,Y or Z wires opening alond the way will cause the sweep to freeze. [img size=1383]http://herkybirds.com/images/fbfiles/images/radar_hdg_reference_loop.JPG

    There are two different ones. D40801, 5935-01-165-0668 D40598, 5935-01-165-0667 And they send a resistance change to the Flight Data Aquisition Unit, which interprets and sends that info to the DFDR as digital data.

  24. Thanks for all the replies. That Aux pump running off the MAIN while it is up sounds like a capitol idea. The TCTO shows 120 manhours, but it also shows 20 of that for hydraulics op chks. Seems like it may have been padded a bit. The TCTO also ran 4 gauge wire back to FS795, right near the pump, and put a terminal board there. Very smart, I wonder if this was thought about for AMP.
  25. I have some suggestion, but you\'ll still have to duplicate it on the ground to fix it. One of the things you need to ascertain is if the antenna quits turning, or if it is just the display not moving. If the antenna is turning, the sweep trace will flash brighter when the heading marker switch hits. They can chech that while they are flying. If the antenna is rotating, then they need to check it on the Nav and pilot displays, in REL and STAB modes. Are you at the \'Rock? I\'ll send you something that may help if it is an indication problem. I\'ll also send some other diagrams I have done up for the system to aid in other problems.
