altering the wheels of your Tesla Mannequin 3, a easy however harmful operation
Sustaining your electrical automobile your self usually scares house owners, however there are a variety of frequent operations which are inside everybody’s attain. One in every of them is to vary the wheels, a seemingly easy operation, however with a number of guidelines to comply with.
Intervening your self in your electrical automobile, it is attainable! Admittedly, there isn’t a oil change to do (though…), no EGR valve to wash, nor engine air filter to vary, however that is nonetheless a automobile with a number of methods that require upkeep and elements. put on that can have to be changed.
On my YouTube channel, I need to present the whole lot you are able to do your self as an operation in your electrical automobile. I personal a Tesla Mannequin 3 and I do not hesitate to place my fingers in the sludge… the order. Who am I ? My identify is François Claire, I host the Storage, Automobiles and Rock’n Roll channel and, with Clear Automotive, I give you this electrical DIY mechanical part (might we speak about “Clear Mechanics”?).
We begin with an operation that appears easy as a result of it’s so fundamental: altering the wheel. That is the commonest operation you are able to do in your automobile. (for instance to swap entrance/rear tyres, change from summer season to winter wheels or keep the brakes), however it is usually essentially the most harmful. Certainly, the automobile should be lifted, which may trigger critical harm or harm within the occasion of a fall. There may be additionally a danger of damaging the wheel and even dropping it whereas driving, if the nuts are incorrectly tightened.
As we speak’s automobiles come with no spare tire or jack. They’re meant to be lifted by skilled bridges. This doesn’t forestall us from doing a protected raise. The Tesla Mannequin 3 proprietor’s handbook states that it’s crucial to make use of the lifting factors situated on the 4 corners of the battery. There are particular pads that match into these lifting factors. You may then use a traditional rolling hydraulic jack to raise one of many corners of the automobile. Or perhaps not… The Mannequin 3 could be very low and chances are high the jack will not go below it…
On this video, I present you the best way to get by with slightly DIY:
As soon as the lifting is finished, the arduous half is finished! Oh no ! To take away the wheel, you should first loosen the nuts whereas the wheel is on the bottom! In any other case the wheel turns concurrently you attempt to unscrew.
You are good to return down the automobile, loosen these nuts a bit with a 21mm wrench and put it again collectively. Traditional cross keys assist you to do that fairly simply. This loosening is just not dangerous to the automobile so long as it doesn’t exceed roughly half a flip.
As soon as the automobile is within the air, all you must do is unscrew the nuts, taking note of the final one: you must maintain the wheel to forestall it from falling by hooking the brake disc as you go. That is it ! You’re Clear Mechanic!
Not fairly: all you must do is put the wheel again in place appropriately and ensure it will not transfer. If it isn’t already accomplished, I counsel you to lubricate the contact floor between the wheel and the brake disc. For this, I take advantage of copper grease which has wonderful resistance to excessive temperatures and over time. Watch out to not put an excessive amount of: it mustn’t come to circulate on the brake disc.
Then, simply put the wheel again in place, begin screwing the nuts by hand and end them with a wrench. Relaxation the wheel on the bottom for tightening and perform a cross torque tightening. If the tightening is dry (with out grease on the studs or within the nuts), then the tightening torque is 170 Nm. If, as in my video, you lubricate the threads with copper grease, you must decrease the torque Clamping. Sure: REDUCE the tightening torque! It is counter-intuitive, but it surely is smart: by lubricating, you make it simpler for the surfaces to slip in opposition to one another. Sustaining the desired tightening torque runs the danger of over-tightening (which is as unhealthy as under-tightening).
The important device for this tightening is the torque wrench. Within the video, I decrease the tightening torque to 100 Nm. It’s kind of an excessive amount of. Now I set my wrench to 110 Nm. I additionally give some further recommendations on ergonomics and TPMS, which I allow you to uncover:
I’m instructed within the headset that this part is doing effectively and that readers are enthusiastic. Excellent ! Apparently, they’d additionally prefer to see extra complicated operations. OK ! The following Clear Mechanics objects are coming and they’ll ship SALE! Uh… CLEAN!
