When should you torque wheelnuts?

Since the manuals usually say that the nuts have to be tightened using a torque wrench whenever the nuts have been loosened if you then loosened them before re-torqueing them the process would never stop and as the period between initial tightening and re-torqueing is usually between 50-100 kms you wouldn’t have time for much else.

Im on at Hanson with Frenchise tipper, ill start checking mine once or twice a week, should be enough :sunglasses:

What is zis 'Anson’s Frenchise teepair? :open_mouth:

Not one of them 'Eeno’s I hope… :smiley:

I’ve just started with Hanson Building Products and been supplied with a new FH13 Drawbar, which I’m very happy with.

As is usual there is lots of daily and weekly checks and the paperwork that goes with it. We’ve been told to torque the wheelnuts every week and fill out a form and sign that we’ve done it. It seems a bit over the top to me (six axles :open_mouth:) , I thought the usual way was to have torque markers which are checked daily and only torque them if they have moved or after 100km if the wheel has been off.

I’m curious how often other drivers have to torque the wheelnuts on their trucks.

Thanks

Depense the Size of Wheelnuts they are usually on big Lorries fitted with 64kg/m You can’t without Special Tool.heck it after 30 Kilometer and they hold.

You retorque just as some Dirth could have been anywhere who loosens the Wheel by disapearing,but finding a loos Wheelnuts is very unlikly if Fitter did Job propper.

just a note about torque wrenches, i spent some years in the Navy as an aircraft mech, torque is taken very seriously. Wrenches are checked for accurate calibration before every use, under supervision. Emphasis is made on the way you treat the equipment, and the way you hold it whilst using it i.e. a pull 90 degrees to the body of the torque wrench

we were shown the difference to applied torque pulling the wrench at an angle can make, its quite something, these are very sensitive pieces of equipment.

the way you see mechanics, fitters (including those are big name tyre franchises) and drivers chuck the wrenches about, use them as hammer etc, its a wonder if they would be registering anywhere near the recommended ranges. You can also damage the internals of the tool, by not winding them off to zero after use, you can also damage them by winding them off to beyond the zero position.

Believe it or not, there is a level or training appropriate to using such a tool correctly and safely, and I think placing this on the driver is taking the proverbial a bit. We already have enough to take responsibility for, a good visual check of the wheels, nuts, threads, and tyres including position markers should be sufficient for our level.

If there is a concern over wheel nut torque then the company should arrange for regular inspections by the fitters or contractors.

Checking wheelnuts is always a drivers responsibility but using a torque wrench is not.

Its a piece of precise measuring equipment that doesn’t take kindly to being abused.

The torque wrench should be calibrated regularly and not just thrown on the shed floor under the fuel pump.

If wheels are removed the wheels need to be torqued up and redone after 50 or 100 miles.

I also would suggest that using oil on the threads can create a false reading.

In my early days in transport many trucks and trailers had different threads, left and right hand thread which depended on the normal direction of the wheels.

I have seen a wheel come off a truck I was in. My truck had blown up and a mate was recovering me and the trailer. I had a 6x2 and had loaded it front heavy. He had a 4x2 and we were barreling down a road in Bulgaria when he said Hey! look at that a wheel is passing us, closely followed by another one as the studs had sheared.

These wheels were getting faster and bouncing higher like the ball on The Prisoner when a woman waiting for a bus was trying to avoid them both. Very Lucky. We had to apologise to her and ask for our wheels back

When should you torque wheelnuts?

what part of you do they want to torque, Wheel Nut :question: :wink: :laughing: :laughing:

Driveroneuk:
Has anybody seen a truck lose a wheel?

.

Yes it used to be a regular problem. Volvo F7s were notorious for it.

When the design of wheelnuts was changed to incorporate a collar, the problem largely disappeared.

oil isnt bad,but Fat is,as it dryes out with the Time and Nut goes then hard to turn

At the risk of losing some work (Agency) I’ve been doing quite a bit for innastate logistics (name changed a bit) this year. They do have some rental DAF XF’s And whilst driving one a couple of months ago I noticed this tiny sticker in the side window next to all the other stickers saying that the wheels on this combination have been changed at ■■■ miles and the wheels need to be checked for tightness within 50 miles. Needless to say ■■■ miles was the beginning of the day and I had done around 300 miles since then. So When I got to a depot I asked for the wheels to be checked.

Imagine my shock when I was told ‘drivers responsibility’ and handed a torque wrench. This is at a depot with a workshop/garage and fitters. Now I’ve never been trained to use a wrench. I didn’t undo the nuts at all, just put on the wrench and pulled till it clicked on all 60 Wheelnuts. I did ask what setting it should be and the tool had been recently calibrated, but thats as far as it goes. Some nuts needed up to 3/4 of a turn.

I can understand a driver using a wheelbrace at the side of the road if he discovers a loose nut, and getting it checked at the workshop, but to expect drivers to torque nuts without proper training, when there is someone about who should be more qualified to do the job is just plain stupid in my book.
