they should be marked
"D" for drivers side and "P" for passengers side,but i guess that would not work in jolly old england.

Re: Knock off Fell off what is the correct directi
Brake reaction torque is OPPOSITE the direction of wheel rotation. That's why the rule: "Left hand threads on the right hand side." This means that brake reaction torque will tend to tighten the nuts.
My dad taught me this when I was about 10 years old as the family's 1949 Cadillac Fleetwood Sixty Special and 1954 Pontiac Catalina coupe had LH threads on the RH wheel nuts, and I always "helped" him rotate tires (the beginning of my engineering education and becoming a car guy). LH threads on the RH wheel nuts was fairly common practice in the industry until the new models that were introduced in the mid-fifties when it was mostly abandoned (at least by GM).
However, with a single center nut on the Corvette KOs, the engineers apparently felt is was warranted, and it was a good engineering decision. Getting users to understand the theory and practice is the tough part.
Another way to check that the KO adapters are installed on the correct side is to remember that nut tightening should be in the OPPOSITE direction of forward traveling wheel rotation.

Re: Knock off Fell off what is the correct directi
Wayne,
Some of us do pretty silly stuff, I'm certainly one of them and have gotten much help from this board. I'm not sure that a sarcastic comment about not knowing left from right is necessary. I'm sure you know way more than I do about this stuff and it is good of you to take the time to help guys like me, but some of the other frequent contributors who also do so much to help, seem to be able to do it without puffing themselves up. If I seem a little sensitive, its probably because this is exactly the kind of silly-a++++ thing I could see myself doing and then writing into you guys for advice and coincidentally alerting others, who might not know "which side is left" that a potential problem lurks out there. Being made to look more stupid than we are might cause us to not write in, and then another of our large fraternity might not get the clue that there was a problem and blithely kill himself. Just my opinion,
Regards,
SteveComment

Re: Knock off Fell off what is the correct directi
Steve,
Sorry if you took it that way. It was not intended to be. Just having a little fun, but you wouldnt believe how many times people ask me what side I mean when I say Left. You just wouldnt. They want to stand in front of the car and point to the left. You have to end the direction by saying DRIVERS SIDE. That usually solves the problem.Comment

Re: Knock off Fell off what is the correct directi
Sounds like a good subject for an article in the Restorer, This is right-where the passenger sits; this is left, where you drive from. And I had despaired of ever having something to contribute. Thanks for the kind response Wayne, I appreciate it.

Re: Knock off Fell off what is the correct directi
Teaching several levels of Automotive Technology, I can tell you that this is one of the most difficult concepts to communicate to students. In editing stories for The Restorer I prefer to use Driver's side and Passenger's side -- just to avoid that issue. I don't want to tell you that I always change the story to that terminology, but I do if I happen to note it.TerryComment

Don't know about today, but yesterday,
Cars were designed on the right side (passenger side) This was standard. The mirror image was the left side or drivers side.Comment

I think they are early repo knock offs, They are not on the window sticker as an option. Still interested?Comment

Problems of this sort are typically....
the result of failing to read and follow GM instructions for 'care and feeding' of KO wheels! First, as others have mentioned, folks get the RH/LH side adaptors installed backwards making the spinners self-loosening vs. self-tightening during normal, forward, driving....
The next common mistake is failing to follow Chevy's installation instructions for the KO wheels. These you can find in the Corvette Shop Manual ('64-65) as well as in the Chassis Service Manual ('66). Regardless of whether the wheels are originals (without safety pins) or reproductions (with safety pins), the installation technique is the same:
(1) Mount the wheels and tighten snugly BEFORE letting the wheel down to hold vehicle weight.
(2) Strike the spinners X HARD wacks and go drive the car Y miles.
(3) Re-tighten the spinners with X HARD wacks and go drive Z miles.
(4) Final tighten the spinners with X HARD wacks.
The re-torquing sequence with intermediate driving is there to absorb any minor wheel-adaptor 'slop' and is IMPORTANT! This is especially true if the KO's are reproductions with 'safety pin' feature....
Inserting the safety pins BEFORE the wheels have reached their final torque value will wind up fixing a loose mounting position of the spinners and allow them move/chew the safety pins creating a potential removal MESS! Plus, if not completely tight, you'll get 'walk' between the adaptor studs and the KO wheel mounting holes that'll generate 'egg shaped' distortion of the wheel mounting holes!!!
It's amazing to me that repro KO wheel mfgr's don't pack care and feeding instructions with their product! It's even more amazing how few owners and supposed 'expert' Corvette mechanics haven't read Chevy's tech manuals to know how to correctly install KO wheels!!!!Comment
