Don't Try This At Home!

I bought a used set of pin drive wheels for my Superformance racing tires (Hoosier A6). The fronts went on fine, but the rear wheels required me to force them on the pins with the spinner. After I had the first wheel on, I realized I didn't know how I was going to get these wheels off! With the help of my F-150 and the wife's Mini Cooper, I was able to use a ratchet and muscle the wheels off. See the pictures! I was really worried about screwing something up big time, but I did it without any damage. Basically, I loosened the spinners (didn't remove the spinners completely), tied a rope to each wheel and pulled them apart using the two vehicles as anchor points.

My question is how to fix these wheels so I can easily slide them off and on? I'm thinking about taking them down to a machine shop and ask them to drill out the pin drive holes 1/32". I thought someone might have a suggestion on how to fix these wheels. Better question might be why are they screwed up? I have a PM into the CC guy that sold them to me....

Other than using a pin alignment tool to double check your pins, and to use anti-seize on pins and mating surfaces, I don't have any comments other than that I'm impressed with the way you play tug of war!!!

Ward….The lugs are simply out of alignment. Don’t mess with the wheels. Get the pins properly aligned. You will probably need a alignment template (tool) to do it. You can get one from Trigo for a few bucks. You will use it over and over so the investment is worth while. The tiniest misalignment (almost imperceptible) will make it virtually impossible to get the wheels on and off. There is very little tolerance. But it is easy to take care of with the right tools. Once you have the alignment tool, you can just tap the pins a tiny bit until you get them properly aligned. It is not scientific….just takes a little patience.

The lug bolts and therefore the pins are out of alignment (not perpendicular to the mating flange on the hub). Get a 2' length of pipe with the ID just big enough to go onto the pins then, with the alignment tool or the actual wheel, see which pin or pins needs alignment and which way it needs to go. I found it best to work on one pin at a time. Put the pipe over the pin and move it in the direction needed, try again, repeat until it's aligned, move to the next one. The alignment plate would be easiest for sure.

I should have mentioned my original wheels came off and on no problem. I bought some used wheels and they are the one's that don't fit. Both of my rear original wheels fit fine on either side. Neither of the used wheels fit. I'll get the alignment tool, but if the original wheels fit fine, I don't understand how my pins can be out of alignment. I wonder what would happen if I tried to put my front wheels on the back just to see if they would fit. I'll order the tool now.

I am just curious...did you see any marks in the rim where the pin made any indents? You could take some bluing and put it on the pins and try to install the wheel again. You will see where the wheel is hitting the pin and be able to adjust from there.

I have the alignment tool and will check things out tomorrow. I could not really see any marks by my drive pins. I'll take a closer look. I have to resolve this as my next autocross event is next weekend!
