Another post from Denmark Previously I showed you my WW2 Zündapp KS600 generating set and now I'm back. It's time to present my Auto Union GG400 generating set, nicknamed "Panzerwürfel" - Würfel being a cube. Most of these sets (and mine too) supplies 12V and 16V, depending of if you need it to supply power to the radios or if you are charging the batteries. All german armed vehicles had one on board, allowing them to be parked in the battlefield with power to the radios without the main engine running. It's a very compact unit but still features electric start per push button, when connected to a battery. Mine as an early model, which were less robust and prone to cracking the engine mount and mine were defective as well. Dating is easy, as the crank is dated (I just love the effectiveness of the germans). Like much of my stuff I have absolutely no use for it, but it is so nice to have . Enjoy! /Steen

Meget pæn Steen. Thanks for posting images.

Thumb and fingers.

Hold the spring down with your thumb at the holder opening and pic out the holder with something sharp. Release the thumb pressure slowly so the spring unwinds slowly

Long time, no post!. Apologies for my absence, had to mothball this to deal with other things. Determined to get back to it, and now the weather has released it's wintery/rainy grip, I've been busy making square brass nuts threaded 3/16" whitworth to secure the 3/4" thick mahogony planks. Finally made a decision on the last drive chain layout. Went for direct drive to the pump. 9 toothed gear on the pump side, so at 2,500 rpm at the engine, 500 rpm at the reduction gear output, gives me 550rpm pump speed. The tech data for the pump with the full cam fitted which I have, is 80 litres per minute at 1500rpm.So this set up will run at 29.3 litres per minute, a comfortable rate for my needs. it meant I had to offset the pump, but not a problem really, and the outlet (elbowed) side will clear the edge of the frame when in use. Here's how it turned out:- Hoping to give it a once-over to check everything is fuel tight, and will get it running without the pump on. I need to 'run it in', as it has a rebored cylinder and new rings to bed in. I'll need to:- Waterproof the Spark Plug and Lead on the head area with a cover, which will also act as an engine cut out. Make Chain Cover for the final drive and oil drip collection tray below it. Waterproof the Air Intake/choke (not urgent). I've made a pulling handle, but need some wood to make a grip for it. So I'm nearly at the completion point at last!. Regards.
