Wire wheel hub nut how tight?


Recommended Posts

HI all, just a quick update on the spinner tightness issue.

Used Roger H's method and after 300 (almost) miles up to Harrogate and back at motorway seeped (officer) still as tight as when I put them on.

Did not stop the car being brought home on a low loader 30 miles from home after the toughened windscreen shattered in lane 3 in the middle of the storms on Sunday, at least now I know I can try juggling with flaming chain saws whilst threading a camel through the eye of a needle as getting across to the hard shoulder was a doddle!

New laminated unit to be fitted Saturday morning.

TR windscreens were always laminated - I am surprised that your car had a toughened screen.

If a toughened screens goes at night, one is virtually blind - very scary (I know because it happened to me on 6 occasions in the 1960s/70s, on cars which were company-owned!).

Ian,

 

I am not convinced of that, why is Laminated windscreen listed as a factory fitted option on the Heritage certificates?

 

Toughened windscreens were the normal fitment on British cars in the sixties and into the early seventies (I had a 73 escort that had a toughened screen go with a bang)

 

Cheers

Hi, I think the laminated screen did not become standard until the mid/late 70's. May have been available as an expensive upgrade as most new things do before becoming the expected standard (air con, disk brakes, fuel injection,...), but I'm just glad they don't make them any more, one thing I'm happy to make non standard, was going to pay extra for the laminated if they offered toughtened, just glad it was light Ian, not sure how it would have ended. Health and safety government nanny state interference, had to be good for something eventually.

Laminated was standard fitment for sidescreen cars AFIK and all TR4 but I seem to remember that after that it was market specific or order specific.Though all I have ever had have been laminated and I have never come across the tell tale small blocks of glass that hidden somewhere in the trim that you can never get rid of.

Back in my younger days when I had a MG I was told to tighten hand tight then then tap to tighten a 1/4 of a turn, I must have been doing something right as in 30 years of wire wheel motoring I have never experienced any problem

An ideal job for an electric impact wrench, I've done it that way for over 10 years.

However you do it use a six sided socket which will not damage the nuts.

Err... best make sure you can accurately control the torque application of any impact wrench used, many rally teams now forbid the fitment and torqueing of wheel nuts by impact wrench because of overtightening, with predictable exciting consequences as studs shear in use and wheels bound off into the scenery. .

 

Also because of the limited flat area available to any socket if you apply an impact wrench to it without the most careful application square in both planes you stand an excellent chance of chewing up the nut as it spins off. If you have done this for 10 years without mishap you obviously have fine motor skill control. I prefer careful application and use of a torque wrench and socket to the nuts where you can more easily control what you do.

Agreed with your comments Mick, I spent 10 years of my career with FMC specifying power tools for the production line and there are quite a few air powered 1/2 in drive impact wrenches which have no torque control and could easily exceed the max torque for the adaptor nuts. However the electric ones like my DeWalt are less powerfull and with a fully charged battery it only just goes high enough. Originally I checked the nuts with a torque wrench to make sure they were OK. Whatever is used it needs to be square to the nut and a good fitting six pointed socket.

When I fitted new adaptors a few years ago I replaced all the nuts as a matter of course.
