All back together for the moment. I can't get a 3/4 drive breaker bar locally today. nor a length of tube up to the job. The compressor valve is stuck from when I last did spray paint so can't open the valve up. [sigh]...there's a jaaaaaag specialist down the road I'll pop on to see him after work and slip him a drink for loosening it off on henry_b's suggestion

The good thing though, not one stuck or sheared bolt anywhere, when I did the brakes everything was copper greased so once breaking the torque everything came apart smooth as silk. so once that damn hub nut torque is broken, it will be about 15min to strip down.

Just the hub nut.
 
There's a new development of houses going up just down the road in what used to be a paddock. after getting everything done back up doing the weekly food shop the mrs suggested we talk a walk down to have a look at them. it's a building site with a show home. along the perimeter fencing are... 2m lengths of scaffold lying in the grass. 'I'm coming back for one of those tonight', says I. no you are bloody not says the boss. Go buy on, not steal one. she has a point. I'll pop up in the next few days to see if I can offer the site foreman a couple of quid for one.. you know.. for next time a hub nut needs doing.

The problem is you buy a 3/4 bar and then it is a whole new lot of sockets. For the hub nut and maybe a crank bolt? How many times is that coming off? I think the hammer action of the air gun is a bit kinder too. Less likely for things to shear. But then my Indy is 5 minutes away and ccouldn't be nicer.

A 3/4 to 1/2 reducer solves that problem but yes I agree on the impact driver. I'll have to service the compressor as it hasn't been used and I turned the reg down for spray paint which isn't enough to give the pressure for the impact gun. joys of only having a narrow window to do car work as back to the office tomorrow. luckily my new job is 2 miles away rather than the 47 I was doing before. I'll let the wife use the cayenne tomorrow and I'll take the RR and stop in at an indi on the way home all it needs is to be backed off some. it's the OEM hub so probably just needs that impact to break the seal.

Think you'll find the reducer will shear off in an instant.
 
Fair point.. compressor now on the list of things to sort

I'd so love to have a plumbed in air system in the garage but the wife will probably freak if I suggest it. my compressor I was given its not your typical home portable one I think the pump is Ingersoll Rand with two air tanks

Who's wearing the trousers?!
 
For these jobs I use an 18v Makita impact gun. Never failed yet. I don't use it for tightening it's ruined more threads than I care to mention. Anything delicates out it just snaps them off!

Latest generation 18V BRUSHLESS XR Li-Ion High Torque Wrench featuring XR 5.0Ah Li-Ion battery technology

Powerful fan cooled motor delivers up to 950Nm of torque and 2400 impacts per minute for heavy duty fastening applications

Up to 1625Nm of "breakaway" torque ensures removal of the tighest bolts
 
We had one of those at my last place - it was pretty awesome - I not sure it is stuck hub nut awesome, if a 1m breaker bar giving it large won't shift it!

Remember Torque is (very basically) force x length

1N is 0.981 kg....

Average Male is 85kg or so, so that is 833.85N over a 1m length or 834Nm - static, bonuce on it and you are adding in acceleration which will increase the force applied (F=ma etc etc)
