Mystery nut/socket combo

It may well have come off a Maybach V-12, but if so it wasn't a 1400 cc engine. Maybach's Zeppelin line of luxury automobiles was powered by V-12s, but they started at more than 6 liters. AFIK the smallest engine Maybach ever made was between 3 and 4 liters and used in cars in the late 30s. However I don't think it was a V-12.

I don't think Maybach ever built motorcycles.

Try "spanner wrench". The easiest way to get one is to take a piece of steel, drill the ID, and saw the "teeth" into the other end. Drill another hole for a bar to turn it. I used to make them from pipe for automotive work. A die grinder with a 1/16" x 4" wheel works just fine. I couldn't wait for the SnapOn or MAC guy so I made my own. One I had to make an actual spanner wrench for was the headlight switch bezel nut on some old Chebby. Old 4x4 3/4 ton front wheel bearing nuts were the same problem. If you didn't have the 4"-ish socket, you might be SOL.

Ford had straight hex nuts and a castellated cap with more slots in it to allow more positions for the nut to be held by the cotter pin.

So, in that case, he can make a curved-bar tightener out of a piece of

I don't think so Carl.. These nuts are made to fit in a recess that's why they are tightened with a spanner that drives on the face of the nut.

I suggest you study the pix of the spanner sockets in question. they are 1-1/2" drive impact sockets!

Now it turns out that this is an "inside joke" in my family; It's funny and ; I laughed out loud...

When an uncle of mine came accross the German for Allenwrench:

Winkelschraubendreheri Inbusschlüssel

He maintained that one of the reasons that Germany lost in WWII was because they could not get tools or parts for their equipment on time - It took to long to write out the requests... ;-}

The "tank engine" that required both this castelated nut, and its wrench, support his belief. I would love to see the original "tank manual" reference for the tool and parts listing... Thanks, JHbs

The mechanics manual for BWM motorcycles used to be printed in four languages in parallel, including German and English, broken down by steps. The English was typically about half the length of the German.

There's a possibility you might actually get your wish. Armored fighting vehicles and associated printed material have been collectors items for a long time. There are a lot more Panther tanks in existence than there are Maybach automobiles. I believe that a lot of the manuals and such have been preserved as well.

OK, so it's a tank diesel, that'd explain the heavy lower end. It also explains the special nuts. In a couple of book I have on armor and tank development, the authors mention that the Germans originally designed their armored vehicles to be shipped back to the factory when they needed service. Not much of a problem in western Europe where railroads are plentiful, kind of hard in Russia where railroads were fairly rare and a wider gauge to boot. So chances are the wrench for those nuts was a non-standard specialty item and was probably only to be found in the factory.
