I actually went down yesterday, Chuck. I probably won't go back for another couple of weeks. I will PM you when I do.

Yesterday was a really nasty day of work. It was blowing wind, cold, and misty for most of the day.

I had a lot of stuff to get done. My main priority was the air system and the cooling system. I brought another sack of fittings with me from the ACE store to connect the last of the air lines. I also brought my rebuilt brake actuator and parts to rebuild the other one.

I pulled the brake wedges from the backing plates to check their condition. They were thoroughly greased at their last service, so thankfully there was little rust. The driver's side wedge had a broken return spring though. I have sourced new wedges from a truck and trailer place so I'll get those before next time. I also found brand new actuators for $60 a pop from a company who is providing axles for the 939A2-series rebuild program. I decided to wait until next time to install the front brake cans since I wanted to replace the wedges.

Next, I replaced the front limiting valve. It had been bashed against the oil pan and a fitting was broken off along with the mounting tab. Thankfully I had a new one in my big box of parts that I had picked up on eBay a year ago. I had to find an adapter on a parts truck and a line to replace one that was kinked. Then, I transferred the fittings to the new valve and got it hooked up. I'll mount it on the bracket next time.

After that I hooked up a couple of lines to the wet tank. One supplied the expeller valve on the air dryer and the other one went off into the unknown.

With the air system done, I went to work on a leaky fitting on the PS ram. Turns out the fitting was bent and cross-threaded! I ended up swapping out the whole ram since the threads in the ram were messed up! Arrgghhh!!

After that, I fired up the truck to check the air system. The dang thing wouldn't build any air pressure again. All of the air is still dumping out of one of the rear relay valves! Next time, I will take all of the lines off of the relay valves, blow them out with compressed air, and lube them. Hopefully that will do the trick.

Finally, I dumped the nasty, rusty water out of the cooling system to replace it with 50/50 since the temps are dipping into the 40's. That made a huge mess, which is why I did it last. It took forever to fill it back up since the only access to fill is through the overflow tank and it only has a 3/8" line going to the radiator. Good design AMG!

I'll post some pics once I get off the road tonight. What an epic project this has been!
