Wheel changes.

You get in & it’s hanging on the steering wheel, please check the wheel nuts after xxxx km.
What do you do ?.

  1. get the torque wrench out of your work bag, note the mileage & do as requested ?.
  2. throw it on the dash & ignore it, there’s nothing I can do about this !!!.
  3. book a check of the torque xxxx km up the road.
    4 Something, anything ?..
    OK I know it’s just to protect the guy & company who changed the wheel, but what are we supposed to do ?.

:confused: :confused: :confused: :confused: :confused: :confused: :confused: :confused: :confused:

call back at thier depot next time your passing ,in the meantime just keep an eye on yer nuts :open_mouth: :wink: you can usually see any loosening

Play the ‘umbrellas’ game if you’re not happy. That’s what the fitter / tyre company are doing by leaving that little note.

I’m afraid Daxi, this day and age is all about ‘covering your arse’ i.e. putting your umbrella up ready for when it starts raining ■■■■!! (zb = cacka-cacka-■■■-■■■!!)

If the wheel comes off a few k’s down the road, who’ll get the blame?? Not the tyre fitter / company; not your gaffer, he’ll blame you same as the police will!!

There’s your answer. :unamused:

One Saturday I spent several hours waiting for a fitter to arrive after I had turned up at a container yard in Rainham to collect a rental tractor unit.
Mid axle had a wheel with TWO wheel nuts missing & I had refused to drive it, the TM was not a happy, or very intelligent man. “Why don’t you just lift it ?”, “Because it an Iveco & none of them mid lift”. “If you drive it to the local Iveco dealers I’ll arrange for them to do it there”, “No, I’m not driving it.”“This is going to cost me a fortune.”

First thing I do before even moving the truck is to get the wheel key out and check those nuts on the changed wheel. I am never surprised when I find one nut which has been missed. I always put the nut markers on and then check the nuts after my first drop.

As far as a torque wrench goes, our fitters don’t use them! - never seen any of them carrying it never mind using it when working on wheels. But they are available for everyone to use.

Most nuts on wheels are self tightening :exclamation: … yes :exclamation: I know some of you are going to say ‘Not all of them’ I used to have to collect new taughtliners from a paint shop in Kettering, each one I picked up in the middle of the night had wheel nuts I could turn with my fingers, I would tighten them with my hands as much as I could and drive for a while, next time I checked you would need a wrench to loosen them.

Its to do with the thread pat, on the right side the thread is backwards to the rotation of the wheel, making them loose. You can get the right side with reverse threads (there is a proper word for it but cant think of it now)

Left-handed threads.

During the 1980’s trucks losing wheels became a major issue and a serious amount of money was put into funding research into the subject. The overall title of the programme was “The Lost Wheels Mystery”.

Despite all the research, the only concrete solution that resulted was to titghen the nuts to the correct torque setting.

In a similar vein, has anyone had a wheel stud shear which, according to VOSA, is impossible to happen in normal usage?

One evening I was running out empty to do a collection when, in the mirror, out of the corner of my eye, I saw something tinged yellow flitting just behind the cab. At first I thought it was a small bird, but as I thought about it further, I realised that it was too dark for birds to be flying.

Knowing that there was a cafe a couple of miles down the road, I pulled in there and sure enough, a front wheel stud had sheared. I presume that it had hit the road and bounced up spinning and that was when I saw it.

I phoned the company and, no arguments, a replacement unit arrived within about 30 minutes.

I call it ‘Left Hand Thread’ (Only 'cos thats what my dad called it when he was an MT fitter in the RAF)

i once had 2 studs shear on the way to the test station so yes they will shear in normal use

I have suffered “lost wheel sydrome”, I had overnighted in a lay-by southbound on the A1. Got up early, went round and checked the load, lights and wheels, they were all there.
When I got to south mimms, I went for breakfast, got back to the cab did a bit of mapreading(central London for 0800hrs) and then checked my load, lights and wheels.
Load OK, Lights OK, sorry, I thought I had a tandem axle trailer, OH POOO, or words to that effect, no wheels on the O/S front axle of the trailer.
It’s a brilliant way of waking up the TM.
Didn’t see, hear or feel Anything, the TM phoned every Police Force from Lincolnshire to London, one of my wagons has lost a set of wheels, the only answer he got back from one Force was “Have you tried the lost property office Sir?”

I subsequently found out that a tyre firm were called in and they found loose nuts all over the place, most of them rusted into place.
Big problem was, I was escorted round to Lantern Recovery to get the job sorted and was put as far as possible into the yard.
I had the Jesus kit on board, in that “OH Jesus, the job can’t start”. Couldn’t even cross load using the big Hiabs on the back of the tractor units.
I eventually got to the job the following day at 1800hrs.

I lost a stud on the front n/s of an Iveco 75E15.

I put it down to the fitter at ATS or Motorway ( can’t remember which ) torqueing the nuts up till the torque wrench cracked then giving it another half turn ( this is a practice that is virtually always adhered to, beats the heck out of me why they spend all that money on a torque wrench in the first place ).

If you read the note left by the tyre fitters it says somthing like check the nuts after 50km or 30 minutes. So if the motor has stood in the yard you can check the torque before leaving.
Then just keep an eye on them, if the tyre fitter or company you work for are using the correct kit, decent compressor and butch enough air gun, then the shouldn’t come lose.
However it can and does happen even if the wheels have been on for some time and regularly checked, but there are tell tale sign that the wheels are coming lose, rust trails on the rim, noises from rims rubbing, nut guards rattling round, a tyre with a shiny rim just like the one you have coming past your truck.

Years ago i had a wheel come loose anyway it didnt come of i spotted it intime but the damage was done to the rim and studs so a fitter was sent with a new {secondhand :open_mouth: } rim and studs, when it was all back together he says have you got a brace and bar to check "em"with later, yes i reply getting the brace and short bar to show him, and if i think they need a bit more i use that extra bar on the end and jump on it, [zb] he shouts no wonder you’ve had problems, about 6’ of bar and you standing on the end :blush: , Volvo give you ample enough torque if you just use the brace and bar that come with the motor and dont stand on it or you’ll strain and fatigue the studs. And this is the rule i go by to this day :slight_smile: , and when i get a spare 1/2 hour i go round them and the trailer aswell, usauly works out to about once a week ocasionaly miss a week :slight_smile: .
