Unearthed Wheel Numbers.

[AH1510]

Hello from the left coast. O.K. boys and girls. I attacked my rear wheel and hub today with the politically correct "simple green". I used the small spray bottle so as not to cause the planet to tilt. This solution is fantastic. Not only did it clean all the gunk off, but it also revealed some secret numbers. So here here is my question, on the inside of the rear wheel, I found the following stamped into the cast wheel. MAX 7.92. On the outside I found the following.  D BMW 36.311238052 ( I take it this is the orig. part number ) Then I found Typ. 250  Type 2.50 x18. Then DOT ALU 32.489.00  Then GES, GESCH
REF. DESIGN KBA. 45002 23150.

O.K. Now I have been in NEVADA. And tried to find the U.F.O area 51.
Also both ways on Nevada U.S. 50 . I think I know about U.F.O."s , but what do all these numbers mean??? If you know, I will help you get back to your own planet. Thanks. OLDPAUL.

My best guess, is that these are material specification numbers, and casting numbers used by the wheel manufacturer, and maybe drawing numbers from BMW, the BMW number, doesn't come up as a good number .

Only set of numbers I am sure about, is the 2.50x 18, that is the size specification in inches .

Pretty sure the MAX 7.92 is the maximum that the rear drum can be machined to in inches?
I guess that was the easy one!

"Simple Green"

Can we get that here in the UK?

Both my wheels are very dirty and need some TLC.

Do you use a stiff (not wire) brush to agitate the solution and then leave it to work?

[Nice_One_Son]

OK, I found it.

Would still like to know whether a stiff alloy wheel brush is sufficient or can I go to a wire brush?

NICE-ONE-SON,
                            I used the simple green in a spray bottle. I was working on the brake drum side of the wheel, along the edge. There are some segments in the casting. I used a soft rag and a #2 pencil with eraser. The eraser is wide enouth to fit in the narrow segments with the rag. I found this simple green at the dollar store when I was buying some plastic see through storage bins. I will use these to put part assemblies in. Head and cyclinder removal starts on Oct. 1st. Now that I have a copy of OAK"S top end guide. A 650 ml spray bottle of simple green was just $1.00. The stuff is made in Huntington Beach, Calif. I am using the Apple Fresh var. Where eye protection as it contains polyethlenglycol ether. WARNING. DO NOT USED ON PLASTIC INSTURMENT PANELS, LEATHER, SUEDE, UNFINISHED WOOD, NATURAL STONE, OPALS, OR PEARLS. Website is www.sinplegreen.com. Just to be safe, I would go with a soft wire brush. OLDPAUL

In preparation for the Lake O' the Pines Rally next month, I've been clean my R65's "mags" using Goop hand cleaner and a nylon brush just slightly larger than a toothbrush. Working great plus it leaves the rims with a nice aloe vera scent.

I use Simple Green, a soft bristle toothbrush, clean rags and Q-tips...works great on road grime.

Works for my ears, too, after a weekend playing ranch manager.
