impact gun for trailer tyres

f140

going to invest in an strong impact gun for opening nuts of silage trailer tyres and tractor tyres etc. sick of trailers with double tyres going low over winter and it takes an age to take them off with the sockets.


I have a 200l compressor at the moment with 1/2 inch hose.
scott was trying to sell me the biggest gun he had for that hose for €300 which he seemed to think would do but I had my doubts. he said it had 1500 torques or whatever the right name for it was


I was thinking of getting the 1 inch hose and a big 1 inch impact gun even if I have to spend a €1000 at the end.

Torque multiplier would be better to shift really stubborn nuts.
Put some stockholm tar on them before you refit them and they will come off easily after that.

Request a catalogue of these guys http://www.ted.ie/ might have some of the answers for you

For wheels not tyres..
Get an air tank of an old lorry and plumb it up to make your air tank bigger.

I have one of these for exactly this purpose:

Run off its own dedicated quick-connector off the 200l compressor through 1" hose, it has never yet been defeated.
I've shifted ancient wheel nuts on muckspreaders and slurry tankers, and silage trailer wheels that hadn't been touched since they were fitted at the factory several decades before.
It laughs in the face of things like tractor halfshaft locknuts, truck chassis/axle bolts, and all the other 'big' stuff that would normally see you going for the cutting torch or the consaw.

If you can supply it with enough air, I'd strongly recommend one.

The cheap torque multipliers don't last , know two lads that got them from different suppliers and both packed up after little use.

Probably not what your looking for. But ingersol rand make a 1/2" impact gun 18v cordless with 1200 newtons. I got milwaukee 18v impact and it gives 650 newtons. So far mine has been strong enough for my work. All got from usa on ebay. The ingersol is about $750. I would seriously consider that over an air operated one. They also do 1" and 3/4".

that's the sort of lad I want. it says it runs on the 1/2 air hose but are you running yours on the 1 inch. 1 inch would be the only job Id say alright

is this one too good to be true?

You need to choose carefully and use carefully!!!

Ideally you need either a 3/4" or 1" drive impact gun for LOOSENING the wheels. Torque multipliers are useful too, but cheap ones tend to fail just when you need them most. The size you need depends on the size of the stud you are opening. 1" guns routinely work on trucks / buses with 18-22mm stud diameters (30 - 33mm nuts sizes) whereas on at least some trailers the studs will be smaller than those. A squirt of good penerating oil helps.

The bigger the air hose the better the delivery of air to the gun, and the better it will perform. Many guns mention 1/2" hose but in reality you need a minimum of 3/4" and 1" is preferable. There's usually an outlet on the compressor tank where you can thread in a 2"BSP nipple and reduce it to suit the hose you want and a couple of PCL 100 series quick release couplings and you're sorted.

Clean the mating surfaces of the wheels and hubs and coat these and the threads with a light spray of light aluminium grease. (It's not done much in Ireland / Uk but this is normal practice in Germany). This prevents corrosion and makes it much easier to take the wheels off next time. Stockholm tar would not be recommended because it's too viscous.

You should find out the recommended tightening torques for your wheel studs and tighten using a torque wrench. But never use the big impact gun to tighten them. Overtightening can stretch the studs and be the cause of them loosening allowing the wheels to come off. Likewise undertightening obviously can cause the same problem. In past times with 3 tonish loads behind a 35 this might have been a manageable if still less than ideal situation, but with modern loads, speeds and roads it's a responsible job now.

Worth spending the right money to get a good gun. less than €1k but more than €100 I'd say. And whatever gun you get, drain the water form the compressor & keep the gun oilled. A 200 litre tank is more than adequate, its the ouput of the pump that will determine how fast you get the wheels off!

Do you have experience using Stockholm Tar? Most farms have it for dehorning and it works very well as an antiseizeing agent.
I have seen big bottle screws on lifts that were seized solid come apart when it was left to penetrate for a couple of months, this was after massive heat was applied and failed.
I do have use copperslip and other antiseize agents but as far as ready availability and low price goes you can't beat it.
Try it and you may be as amazed as I was!

ferryman35

I do. And I have lots of experience with wheel studs too.

some real good air tools recommended in that lot ,i'd just add if there is a garage,or commercial truck repair centre near you give them a shout ,or truck tyre centre roadside repair van operator and ask them for their recommendation,or worst experiece and name of supplier, certainly 1" air supply with big air reserve tank is a must, they should be drained daily,don't forget the air tool oil, steer clear of cheepies

We' ve a 200l compressor, 1" hose n 1" kuken air gun. The mobile tyre man bill was getting too high.
It has whipped off many a super single etc.
Handiest bit of kit we got was a tubeless plug kit off ebay for a tenner. 20 plugs n the needle for it- the last time the tyre van arrived it was e65 for one!

Spend your money an the 1 inch hose and inch gun.
Invested here a few years ago and yet have to see it fail, think it cost around 600 euro.
