Casar66 Posted December 18, 2020 Report Share Posted December 18, 2020 (edited) in a german forum I read about the correct use of the centre lock spinners. Some say the spinners with "right side" imprinted belongs to the right wheels of the car and the one with left side imprinted on the left side. Other say the imprinted "right side" or "left side" means the direction to "undo" (also imprinted) the spinner. And they say also that if you use the wheel spinner (and the adapter too) with the imprinted "right side" on the ride-side wheel you will loosen the wheel sooner or later because the "undo" is the same than the driving direction. I mus admit that I have never took care about this issue. And I have never lost a wheel due a loose spinner since many years. But I just had an eye on my car and what did I see? Exactly, the spinners with imprinted "right side" are on the cars right side, and the left are at the left. Do I have to be happy to be alive?

Stagpowered Posted December 18, 2020 Report Share Posted December 18, 2020 (edited) Our local group leader told a tale from many years ago when he was taking a car for its MOT test after a rebuild. He had fitted the spinners on the wrong side (never thought to check) When the first front wheel fell off after a couple of miles he just thought he had forgotten to tighten it (it missed the bodywork as it fell off and he rolled to a halt on the brake disc. Shortly afterwards the other front wheel parted company. This time it happened at the top of a long downhill section and he then had to persue the wheel for half a mile, but fortunately it missed all the other cars and ended up in someones garden. It was at this point he realised why the spinners are marked left and right! Yours are on the right way round Neil Edited December 18, 2020 by Stagpowered Quote Link to post Share on other sites
Casar66 Posted December 18, 2020 Author Report Share Posted December 18, 2020 again for my understanging: correct is... right-side-spinner for wheels at the cars right side. undo in direction of driving. left-side-spinner for wheels at the left side. undo direction in direction of driving.

Z320 Posted December 18, 2020 Report Share Posted December 18, 2020 (edited) Hi Casar, the rule is very simple: the nut on the center of a spinning shaft need a thread which has to be locked in the opposite directon of the spinning direction. So - wheels on the left side spin anti clockwise, so the shaft and nut on the shaft need a thread to be locked clockwise.

Casar66 Posted December 19, 2020 Author Report Share Posted December 19, 2020 That wheel is on the cars right side. Wrong or right? Quote Link to post Share on other sites
roy53 Posted December 19, 2020 Report Share Posted December 19, 2020 think of the arrow as rotation Roy Quote Link to post Share on other sites
RobH Posted December 19, 2020 Report Share Posted December 19, 2020 Yes that one is correct. Think of the wheel rotating as the car moves forward while the spinner is being held steady. That must tighten the thread. Quote Link to post Share on other sites
Casar66 Posted December 19, 2020 Author Report Share Posted December 19, 2020 Quote Think of the wheel rotating as the car moves forward while the spinner is being held steady. That must tighten the thread. But will it not "untighten" the thread when the car moves in the same direction like the "undo-arrow"? Perhaps my brain is in hibernation-mode already.

Z320 Posted December 19, 2020 Report Share Posted December 19, 2020 (edited) you only have to keep one thing in you mind: to lock is the opposite direction of the spinning direction Edited December 19, 2020 by Z320 Quote Link to post Share on other sites
Casar66 Posted December 19, 2020 Author Report Share Posted December 19, 2020 ok, hope, that I got it, my wheels are on the correct side, even if I do not understand it. Quote Link to post Share on other sites
JohnC Posted December 20, 2020 Report Share Posted December 20, 2020 I read somewhere that there's a theory that the (very) small radial movement of the wheel on the splines as it rotates (and as the load therefore rotates around the wheel) actually tightens the spinners. Can't say I've noticed it myself. But I've always taken the view that the words "right side" are a clue to which side the spinner should go Quote Link to post Share on other sites
Z320 Posted December 20, 2020 Report Share Posted December 20, 2020 I've also been told that but it is only sweet wishful thinking. Quote Link to post Share on other sites

Phil Read Posted December 20, 2020 Report Share Posted December 20, 2020 The system is the same as on commercial vehicles. On the O/S (right side, drivers side in the UK, passenger side with a LHD) they are left hand threads they tighten anticlockwise and on the N/S (passenger side in the UK, drivers side with a LHD) They are normal thread, they tighten clockwise.
