    I got new parts to re-install the intervehicular connector. And the lights at the rear are working as before.

        Plain encased seal at the axle shaft

        Richard Lehr  4 December 2015 20:06:00
        Since everything was done, the first year ended up in more maintenance work. Or better: investigation. It was not possible to find the seal (NSN 5330-00-410-2329 | P/N 11640306) which seals the axle shaft and the brake housing against dust and water. A friend of mine made me one which I installed together with a new axle shaft and deflector.

        First it started with the seal. We used a material which might help to survive the next century

        And this was the final result:

          Happiness and Sadness

          Since everything was working well on the brakes. I made my first offroad test drive.

          I do not know why I checked the inside of the drums. But it was a good idea. From where is this mud and dirt coming?

            Brake Lines

            Richard Lehr  22 August 2014 18:35:00
            Because of the trouble with the rust and dirt, I was happy to find some NOS brake line which are located in the brake drum and fitted to the wheel brake cylinder.

              Wheel stud modified

              Richard Lehr  14 August 2014 15:10:00
              In a turning shop the wheel bolt was modified so that it can no longer rotate when the nut is tightened.

                Brake Shoes

                Richard Lehr  5 August 2014 14:48:00
                Received "like new" brake shows today. The new brake pad on the original shoes are glued not riveted. Does not matter, the main thing is the Goat brakes.

                              It was not possible to get off the drum on the front axle's right side. Got a nice endoscope from a M151 driver in Hanover and had a first look.

                              What you see is the housing at the bottom right and the bracke backing plate at the upper left. And there is something in between which shouldn't be there ...

                                Drum on the first axle on the right side:

                                A nightmare. Looked like somebody has forgotten to close the holes in the drum - RTFM.

                                What I found inside was brickearth and a broken return spring.

                                  Just a little bit of oil.

                                    Half way on my way home from the freight forwarder's yard I lost brake pressure. Wow, what a nice situation having no brakes on a 3.5 ton truck. As I wrote before the Goat's brake drums are filled with overpressure and the air is coming from ... the engine. The engineers have forgotten to put an oil separator in the vent line coming from the engine and going to the wheels. Known issue ...

                                    First I opened the drum of the second axle on the left side:

                                    It looked like an oil pan after draining.the oil. Excellent rust-proofing.
