AMG 3 piece OZ Wheel Restoration

Posted on 2221 views

I had my first set of these beautiful AMG 3 piece wheels on my 1988 Mercedes 300CE in college. I had to trade a new chrome set of AMG Monoblocks and some cash to get these. I remember repairing cracks in the barrels due to pot holes which happened more than a few times. The wheels were never quite the same after any wheel repairs. Its been 27 years and I decided to dive back into the AMG cars I loved when I was young. I acquired a set of AMG staggered wheels for a 500SEC and a 500SL but both are in desparate need of a restoration. I either had to take them in to a professional wheel company or I could try it on my own….

The first thing I needed to do was soak the wheel bolts with a penetrating oil for a few days. I ordered the correct sockets which took 2 week to arrive from overseas. The 35 wheel bolts on each wheel were removed one by one and it felt like an eternity. The wheel bolts were first soaked in degreaser for a day before dropping them into a vibration tumbler using 2 different types of media over the span of a few days. The bolts came out much cleaner than I expected but still not sure if they shiny enough. I will polish each bolt and see if I can get them to shine a bit brighter. If they dont, I can take them in to be nickel plated.

The lips were incredibly dull and the clear coat was worn away in some areas. I decided to try paint stripper to remove the clear coat. It worked pretty well. I then used various pads to clean and polish the lips. Its a huge improvement but not professional quality. I’ll try to polish them even further but may need to take it to a shop. The inner barrels have so much crud that needs to be removed. I think I may have to separate the halves and paint the inner barrels or they wont look correct.

    Hi! I just picked up a set of the 3 piece amg myself. They need to be completely restored. I was thinking to just replace the barrels and the bolts. Then having a shop refinish the faces. Have you looked into it? Found any good sources?

      I have looked at replacing the bolts. The bolts sold do not have the OZ raised lettering of the orignals. I am going to redo my original bolts.
      Where are you located Moe?

        Located in San Jose, CA. Yeah after doing some digging that seems to be the case! I might be replacing the inner and outer barrels, as all of mine are pretty much either bent or cracked.

            After doing a bunch of research. Multiple back and forth conversations with OZ. There’s no way to get actual OZ barrels or lips anymore with the original part numbers.

            There is however: for example who is selling everything for them. Granted, not OZ brand. But I hear good things about them!

      any pictures?
      Did you polish the bolts?
      Did you rechrome the original bolts?
      What color did you paint the centers?

        Hi, do you happen to know if anyone in the past 15 years has attempted to create replica or reproduction faces for these 3 piece OZ AMG wheels? These is a lot of information about the faces for these wheels cracking from mistreatment in torquing or using come lugs in a ball seat, etc.
