Please confirm direction of knock-offs

at work here the guys tell me that the friction on the back face of the wheels against the hub is the primary driving force, and the pins are purely to locate the wheels in the correct place on the hub.

but I have seen posts where folk state that if you dnt add some grease or similar, then the wheel(rim) can rust on making it a SoB to remove.

Yes - the pins transfer rotational force but the spinner applies the clamping force that keeps the wheel on the hub.

I got the lead hammer today- FROM THIS SELLER and had my the spinners off within 10 minutes. I'll be taking them up to the tire shop to get the Billboards mounted tomorrow. I'll start a new thread with pics after they are mounted. Thanks for the tips guys!

A extra tirck is to take them off at least once a year and apply antiseese preferbly twice is better! Watch Dennis video, they don't ned to have the crap beat out of them to be tight!

This is one of my favorite pictures because the replica I'm building is very close in appearance to this original car. But I noticed some time ago that based on the way the knockoffs are wired, they appear to be on backwards.

Everything everyone said above. When you want her to take something off, you need to be a little forward. When it's time for her to go, hit her in the a**!
Getting old frozen ones off can be a chore. There are posts about that here. Putting them back on, I always use the Permatex (Napa) anit-sieze (dissimilar metals). Also, dont forget your safety wire on the spinners when you're done. There are posts and even videos about that here too. Good luck!

Right on, Dan

The reason they are tightened toward the rear is that when racing, they would be next to impossible to remove if they were tightened toward the front during pitting contrary to the thinking that they will loosen over time.

Please explain why they would be next to impossible to remove.

Some of the Corvette guys argue about this from time to time (which direction is best to have the knockoffs tighten). The knockoff secures the wheel through clamping force (tension) which along with friction also secures the knockoff. As long as the knockoff is tight - it doesn't matter. But - if it looses it's tension (clamping force) and becomes loose - then the matter of rotation might make a difference. Maybe not much - I wouldn't be too happy if it spins off under acceleration, or under braking - either one.

Send it back. 14 pounds is WAY too heavy for this usage. A 6 pound is more than adequate and what virtually everyone uses.
You don't want to bash that much torque into them and if you miss with14 pounds, you'll crap the rim. Learn the feel of tight with no further movement (wheel down) and stop there.

Dennis also mentions in that video to loosen the spinners and apply antiseize as necessary every 2-3 months. PITA, I know, to rewire and everything, but might alleviate bigger issues down the road. Like buying new spinners.

Surely that isn't correct. It looks like the 5 to 6 lb hammers I have from the picture.

I know that hammer -- it's a monster built by the Cook Hammer Company. That's model 123 and you can check the specs right off their web site: Cook Hammer Company It is indeed over ten pounds and over two feet long.

Well, only theoretical but I believe if they were tightened to the front, the inertia and centrifugal force on the spinner will tighten the crap out of the spinner under braking as braking force is magnitudes more than acceleration force. I had my spinners on backward (tighten to front) for about 1500 miles. I realized my mistake soon after install but decided to run it and test my theory. Each spinner was wired with an inspection loop and I checked it before each ride to see if the loop stretched. It took two people, a 2x2x4 piece of hickory and a sledge hammer to get each corner off. I split the hickory twice and cut it down twice before all four were off. I use antiseize and about three whacks per tong like the posted video. You can feel and hear if the wheel is seated and then one more whack for good measure. I always have the wheel off the ground unlike the video (like you would in the pits). If you need the wheel on the ground to loosen the spinner, then they were too tight to begin with IMHO.

It is indeed pretty heavy, my arm was burning while using it. But it worked great, I finally got them off and got my Billboards installed.

[Got the Bug]

Removing my wheels and re-applying antiseize had been on my list of to dos for a while. Finally got to it today after 18 months. Took a little more work than usual to remove them, but nothing major.

[TButtrick]

... oh, and another tip. Once you crack the spinner loose, put your finger in the middle of the hup and press while you undo the spinner with the other hand. It will save your spinner from bouncing off the rim and onto the floor. Great tip I picked up off this forum years ago. I love you guys.
