loose KO spinner

[Steve Robinson]

My left rear KO spinner keeps loosening up. All the other wheels are fine. Any thoughts? Could the threads on either the spinner or the adapter be stripping? These are direct-bolt repro KOs.

Get it tight before installing the lock pin. These LARGE threads would be hard to strip.

Steve:

Look at the relationship between the adaptor drive pins and the wheel. If there is any radial play there, I believe will be your problem. Maybe not. That's where I would look first.

Steve,

Upon reading your post carefully. I understand you to say that these are BOLT ON reproduction KO wheels. If that is the case then safety is not an issue here. I would just use some masking tape to take up the extra clearance on the threads and go on down the road. Loosing the spinner and cone is the only problem here since the wheel itself is bolted on. Let us know how this works out.

Re: loose KO spinner

Thanks for the responses. I guess I wasn't clear. While these are repro, they are real KOs--nothing else to hold the wheel on but the spinner! So it's a bit urgent!

Check the adaptor/spinner threads

While you're in there, take the wheel off and see if the spinner will turn all the way up on the adaptor threads without binding. You may have galled threads at the point where the spinner contacts the wheel.

Steve,

OK, let's take another approach. Most of the time that loosening is caused by an installation error. Make sure you are seating the wheel on the pins and not trying to seat on the lug nuts. Seating on the lug nuts will work for about ten minutes and then she comes off!

Thanks! I think that may be it.

Re: Check the adaptor/spinner threads

1) Make sure you have the left hand wheels on the driver's side, and the right hand wheels on the passenger's side. If you don't, the spinners can loosen on their own.

2) Make sure you follow the installation instructions exactly. If you don't have the instructions, call Corvette America and they will send them free.

3) Make sure you use a lead hammer to install the spinners. Rubber hammers, dead blows, etc. will not generate the 450 foot pounds required to secure the spinners.

4) Make sure you use the safety pins as specified in the instructions.

5) Check the wheels frequently to ensure they are secure.

Hi Steve,
One more thing to look at are the 5 holes in the wheel that the adapter pins fit into. These need to be round and have a nice fit on the pins. If the wheels holes have become egg shaped, it lets the wheel rock back and forth as you accelerate or brake.
Hope this helps,

Yes indeed. Thanks very much.
