New Wheels, Stripped Threads

Hi guys

I bought a set of advan sa3r second hand 17"

My old nuts were too fat to fit inside the new wheels so i bought a heap of new ones.

The ones i bought seem to fit perfectly, but i have just taken the wheels off to spray them black and the front right wheel had 2 nuts that were so tight, even after using wd40 and a bit of oil to lube them up we could bearly remove them by jacking it back and forth until it finally came off very reluctantly. It wasn't like they were tight for a small part of the thread but from start until finish.

2 of the studs are partly stripped of their threads and need replacing as well as the 2 nuts.

I'm wondering how this could have happened so i can avoid it in future. im not a newbie to wheels and know not to overtighten or cross threads and what not else.

Btw, what are the stud sizes because i need to buy some more (and hopefully from a wrecker).

the two studs/nuts have been cross threaded.

shit happens.

this might have been caused by you putting them on wrong, or the threads on the studs/nuts not matching, or even being way over tightened.

just be careful next time.

when removing a wheel, i jack it up a tiny bit then crack/loosen the bolts while its on the ground (always doing opposites), then jack it up then undo it all the way.

when putting it back on, (again doing opposites) i tighten the bolts slightly to around 30% torque while the wheel is in the air, then drop the car and do them up all the way.

are you sure you used the correct pitch nuts? You said you used new nuts , were they all the same ? Nissans use 12x1.25 mm pitch, same as Subaru, others use 12x1.5 mm pitch.

You can buy the studs new from Nissan

i hand screw them in 90% of the way and only tighten the last bit by hand and i only tighten them enough to hold and check them the next day so its very unlikely i've overtightened them or crossthreaded them.

I do them in opposites from each other but i crack them on the floor then jack right up to unscrew and losen, that could do this?

The nuts are 12x1.25

cheers

Its very hard to strip them by overtighting them you brake the studs first.

Thats the way you should undo them, do them up. Maybe you had 2 different studs on? someone changed them to 12x1.5 mm before ?

Ye, unless you cross threaded em, possible wrong studs were in there?

Other than that... being a bit over zealous on the tightening wont cause it as above.

Sounds odd if your 100% you put em on correct and they came off good also

Hi,

Had a similar problem on my much modified RX2. I had installed longer studs with a different bolt PCD. The long and the short is that the taper where the nuts seated in the rim was different to the taper on the nuts. Therefore when tightening the nuts the tapered end was forced narrower causing that part of the nut to bind on the stud...check the tapers and compatability of the two tapers.

Regards,

Jeremy

      Stock RB fuel pressure is near enough 43.5 psi, so the latency in that table at 31.6 will be close. You can see that 7 or 8 psi equates to about 0.4µs extra latency. So if you wanted to interpolate between the 31.6 and 39.9 psi values you could say you're going up about 2 psi out of those 8, so add about 0.1µs, which is barely worth talking about and is quite possibly wrong because ideally you would fix the latency while running at the appropriate conditions on the dyno, with a wideband sniffing its butt.

      The pressure, is what you set the fuel pressure to. If you have the factory fuel reg, you'll need to find the factory spec. I don't know it off the top of my head, but someone else might.

      Belt flex under throttle

      For others, what GTSBoy states here should be paid attention. Why? Well lots of people play with different engines, and they LOVE to change things like remove AC, or steering pumps etc, and it lends to them needing to move the tensioner too. You want your tensioner, particularly those that are sprung or hydraulically tensioned, to be the first thing after the harmonic balancer, or technically the "last" pulley in the chain. By saying last pulley, I mean look at the direction the crank spins when the engine is running, follow the belt from where the crank is pulling the belt FROM, and keep following that until you're between the last pulley/accessory on the belt and about to reach the crank again, this is the spot where you put the tensioner. This is the area that will always end up with slack. This is worked out exactly the same way for chains too, as the physics is the same for them. The crank pulley is where all the force to drag the belt around comes from. You will never ever get rid of the slack that appears, especially under load. The tensioners job is to keep the belt loose enough when stationary that there shouldn't be out of sync movement in slow movement, and then be tight enough when running, that the belt can't jump off any gear and get damaged. Too tight, bad things happen, too loose, bad things happen. Have a tensioner (mainly sprung/hydraulic one) in the wrong spot, it can't actually do anything about keeping the tension.
