I moved this from the other thread as it's of more general interest...

Also the Rod Ends setting is different - was 120 before

I assume this is direct from the Factory as at 14th March 07 ?

No bruce - just found this from an earlier search - Ross posted it

On another note that reminds me - will you be bringing any of the owners manuals along this wend - love to get one?

I used a torque wrench to do the wheel nuts up on my wheels last weekend.

I must admit 96Nm doesn't seem anywhere near as tight as I would have usually done them up! But maybe I've always over tightened them!

Funny john - just torqued mine properly - took the wheels of checked everything around the suspension, all nuts , copper grease etc

When tightening them - you're right 96NM didn't feel enough , and the threads aren't very long

I did however try and undo them with a standard wrench after and they are very tight - so i'm sure ok BUT i will be checking them a lot more often now

Back to the other thread...

Been out all day in my Atom and all four wheels are still on!

Do people not find it odd that Ariel use both imperial and metric bolts on the cars... WHY

[ross]

Nope, after all the fuel tank can take gallons or litres of petrol!  Clearly a car designed for all markets

Because its British!!

My Ginetta's the same - I wrongly assumed that because it was built within the last 3 years, it might use all metric fasteners. I was wrong!! Its a combination of UNF, UNC, Metric and Metric Fine.

I know the Atom uses some UNF and some Metric stuff - but I wouldn't be surprised if there's Metric Fine, UNC, and probably a bit of Whitworth in there too!

[Bruce Fielding]

What about Whitworth?

What about him?

[AtomFun]

Do you mean Harryworth?

Showing my age now!

[Alec]

Probably Joseph Whitworth of BSW fame but why the query I don't know unless he's implying there aren't any on the Atom.

And if anyone's going to show their age it should be me.

Its not the bolt types you should be worrying about...

Its the loose screws.
