topo... could you tell me a part number for the one you have? I would like to add it to our parts list that we are making to post up for everyone as soon as it is finished.

Here are the internals of the two low air pressure switches I have. They seem simple. I am going to try to make one good one out of the two. The one that was originally on my truck is on the top. The one that worked for just a little bit is on the bottom. The next picture is them both...

Yes we can excuse it. I was surprised it worked the other day when I put it in, even though it only worked for a little bit. I may try to take one of the switches apart too and see if they can be fixed. Does anyone know of any new made low pressure switches that will work in place of these old...

I have been out pulling buzzers and testing with the multimeter. After trying both pulled buzzers, neither of them turned on, so out of curiosity, I started checking voltage. There was no voltage coming to the wire that hooks into the buzzer. So that lead me to the low air pressure switch...

Not yet. Mine are good for now. I have just read that they are prone to cracking and leaking but didn't know that they could be welded and reused.

Is that a weld on the lower piece? Can they still be used if they are welded?

Looking for ground was my first thought as well, but like you, I really have no idea. I didn't think a ground would be a problem since that buzzer looks like it has been in place for a long time. I am going to wire wheel the contact places when I mount up a replacement one to be on the safe...

Do we still need to see the inside of it then? Back to the parts trucks....

Haha! Well darn...I was hoping I wouldn't have to do that. If it wouldn't have gotten dark so quick I would have taken the buzzer off and wire wheeled everywhere it made contact with the firewall just to rule out the ground.

I am half way there on the air buzzer. The low pressure switch was replaced with one from a parts truck. The switch is good, does not leak air and made the buzzer come on for a little bit. The buzzer sounded weak, so I tapped on the outside lightly and it started to sound pretty good until...

As soon as I get a few more things found, I was going to figure out how to post the list into a thread titled "G749 Parts List" or something of the sort and ask a moderator to make it a sticky. I sent the most recent edition to your personal email just now. I used this for a breather hose since...

Here are all of mine.

Man you know your stuff!!! To the parts trucks it is.

Air Buzzer I have been working on the air buzzer today and now need to ask for some help. I am not understanding how it works or how to fix it, even with looking in the TM. This is on the driver side just below the dash on the left side of the steering column and I believe it is the air...

Looks good. What color are you using?

I was out doing more work on my truck today and pulled some parts off of a parts truck. I thought this bridge plate cleaned up nice. Before and After (Yes it is the same plate) I'm sure happy with it and did not expect it to turn out so well.

Definitely get TM 9-8024. It will help you a lot. Also NDT is right on as well. Looking in my manual under the transmission troubleshooting, it shows the following as possible causes of your problem: 1. Rear Band 2. Transmission Shift Lever 3. Manual Linkage 4. Rear Servo 5. Transmission...

Gaskets Here are the compressor gasket templates Gunfreak referred to in post #4.

I fixed my fuel sending unit today. There were three rivets holding the housing together. I drilled them out on the bottom side that goes against the gas tank and opened it up. There is a wire wrapped piece that a little brass contact that is hooked to the float assembly rubs up against. The...
