Compressors and rattle guns.

[bananas]

What power compressor and size tank would be needed to change four wheels (4 off then 4 on) without sitting around waiting for enough pressure.
and what torque rating for the gun would be needed?

Dewalt 36V 1/2 impact wrench - 440NM

I have the smaller 18V 1/2 impact wrench and at 330 NM it certainly makes short work of a change of tyres - priceless as far as I'm concerned.

Might be cheaper, more convenient and take up less space than the tank and compressor - charge it on the move from an 12/240V inverter

Just a thought

Wurth 18V 1/2" impact wrench, 650Nm

8 cfm or there abouts.

Electric is the go, no hose, less noise.
I run both makita ones and am very happy with both. From memory they were $180 ea.

[bananas]

8cfm. Damn.
The problem with electric is how expensive they are. $300+ just for the wrench and a battery, maybe a charger. And it cant pump or reseat tyres.
How would a 4cfm compressor with a 40 litre tank go? Down time between waiting for it to recharge?

As long as the wheel nuts arent overly tight (properly tensioned, neva sieze on threads etc. 80-90lb/ft is about right for most M12 stuff) any cheap rattle gun would do the job, a more expensive one will do it better and longer.

As for capacity, rattle guns are usually alot less hungry for air than other air tools for example air ratchets, so if you have a big enough tank to reseat the beads on your tyres, you probably have enough to change the wheels over I reckon.

But having said that, if we do any long trips, I will be throwing in my 18V Repco rattle gun I use at work, it just makes things so much easier. That will easily change a set of wheels on one charge, hell its got enough grunt and capacity chargewise to pull as gearbox out of a LandCruiser on one charge lol.

Wurth 18V 1/2" impact wrench, 650Nm

You only have to undo them , not rip 'em off !! , that thing would just about suck em through the backing plate

I have a sidchrome air rattle gun ill sell. Used once.

If you go lithium ion Milwaukee is the way to go, better than Makita or the other brands commonly found at local tool stores. The initial outlay is more but they out perform most other brand power and quality wise.

It snapped the odd automotive grade bolt before I got the hang of it. But then it will also undo some big ass nuts/bolts on fine threads, think Jag front spindle bearing nut or RR wheel bearing nuts

It cost me $899 in a kit with their 18V 1/2" drill, charger and two batteries, best money I ever spent in the workshop, use both tools pretty much every day.

Quick question, how do you change four wheels on/off at once?

If you change one corner at a time, or even two at a time, by the time you remove a wheel, put another on, get nuts threaded on, how much air do you really need?

[hulsty]

I use a supercheap rattle gun on a 15L tank to ARB compressor, changing one wheel at a time I have plenty of air to do the job, normally crack them with the breaker bar then whip them off with the gun.

I was going to buy that Milwaukee impact gun. Ended up with a 3pc kit with a 1/4" impact. Its 160Nm of torque, but thats enough for wheel nuts and most other nuts on the car. Batterys last for ever and its half the size of the 1/2" impact.
Just need a 1/4 to 1/2" adpator and a 21mm socket. Works well for me.
I didnt think it would work. But seen a mate use his dewalt for the doing wheel changes.

Wurth are made by Milwaukee.

I got a cheap 18v Ryobi 1 from bunnings with a drill and 2 batteries for under $200, Works a treat i cant kill it and will happily change a set of tyres Both on and off with wheel spacers on and off and its still going strong. I wouldnt consider carrying a air rattle any more.

[Lepa]

i change mine with a panasonic 14.4v impact driver with a socket adaptor. i crack the nuts first, use the drive to get the wheel on and off and tighten with the bar. does me fine useless i'm hungover and don't tighten with the bar - then the ute ends up on a tow truck!!!!!!!

^^This.
Once you get comfortable with it, you can use it for heaps of stuff. I have the same kit plus other Wurth stuff. It is great.
