Default I feel a new tool coming on

went to undo the drive shaft nuts on the Tourer I recently got, no chance with a ordinary socket set so I ordered a 3ft 4 inch breaker bar, just under £17. Felt the bar was going to snap, the nuts holding fast.

A neighbour lent me his 240v impact gun. It needed a few attempts but by god it did both nuts.

This is what he has, Clarke CEW1000 Electric Impact Wrench 240v,

450Nm of torque



Feel I wasted my money on the breaker bar but never expected the nuts to be that tight, I had un-peened them.





Generally it would be quite a faf to use, get extension lead, get impact gun where ordinary socket and extension bar normally will do but in times like this, it is worth the agro of getting the extension lead out.



May be a new toy for myself.. really impressed with it

3 foot breaker bar? I've had a 7 foot piece of scaffold that slips over my torque wrench for years - never let me down! Have taken hub nuts off with one finger and it only cost me a tenna!

I have one of those Clarke impact wrenches too. Great bit of kit that has never failed to undo anything
Not my most frequently used tool but, a god send when needed
A lot safer than bouncing around on the end of a scaffold pole too

I had wondered about using my big torque wrench for trying to undo the nuts but decided that it is a precision tool used for doing nuts and bolts up to a specific "tightness" and so decided not to use it for undo the nuts.

I'd already broken a socket wrench so did not try again with a spare.

I have two - one bought by my Grandfather in 1964 and one I bought on Amazon a few years ago. I use the former for precision and the latter for brute force with scaffold.

Yep I have one of those and they are a good bit of kit.

It has undone just about everything asked of it but failed miserably on the diesel crank pulley bolt.

5ft scaffold bar with me swinging on it soon had it loose.

Had to replace the hub on the wife's Stilo Abarth the other weekend. Mate of mine and ex-truck mechanic was giving me a hand as I didn't have a 36mm socket needed for the job.

He said I'd never get the drive shaft nut off and bought his big breaker bar with him. I'm probably about 6ft1 and at least 18 stone and wasn't getting anywhere with it. I bent my trusty go-to big levering stick on it too.

Anyway; father bought me a 240v electric impact gun for xmas so gave that a try. Mate wasn't convinced it'd have it off and was certain we'd have to get a longer lever for the wrench to undo it. Had it off in seconds. Couldn't believe how effortlessly it had it free.

It's a bit weird as it's not quite like a windy gun that rattles quite hard and fast. When it's trying to undo something hard it like winds itself up and gives it a hell of a thump every few seconds. Compared to my proper windy gun and compress it felt odd and I thought at first it was broken and not doing anything but it worked like a charm.

I have the Von Haus gun rated at 500Nm...

Compared to having my windy gun out it's much better; otherwise I have to drag out the extension lead, power up the compressor and let that build pressure, then run the hoses and oil up the windy gun. Then have to wait for the compressor to build every now and again. Much less hassle and generally a bit safer than hanging off off a wrench and snapping something.

I had one of the Clarke electric impact wrenches- I did not find it that good. It did not shift a crank pulley bolt, and also did not touch hub pinch bolts or some wheel bolts that had been over-tightened by garages. Then it packed up, so I have binned it. I tend to just use good penetrating spray (I always use WD40 fast release penetrant - usually works for me) and good sockets/breaker bars. Perhaps a bit of heat if something is really stubborn.
If you are going to get an electric wrench, spend decent money and get something like a Milwaukee one that pulls 1000 Nm or more. My local garage uses these, and I have borrowed one from them occasionally- they are seriously impressive.
