Does anyone use a cordless impact driver /wrench to undo stuck bolts - if so which one do you have and would you recommend Thanks
What bolts are you talking about ? I’d need to find the tool reference but I use an 18v DeWalt 1/4” drive impact wrench on bolts. Andy
i have a milwaukee fuel 3/8 drive for the car but would be very overkill for the bike but depends on intended use... cannot think of that many fastenings that would require a power tool other than bolts for engine casings etc but then id use a 1/4 drive if any at all
Hmmmm, you need to be careful not to go in too heavy on a bike. For cars and trucks maybe but I'd be wary on a bike. Bit of plus-gas and going tighter before loosening often does the trick for me, or a bit of gentle heat on the job and a gentle touch...
I got this one as I had the batteries and charger for my drill - but I'm sure it was only £145 when I bought it earlier this year Highly recommended. https://www.screwfix.com/p/makita-dtw450z-18v-li-ion-lxt-cordless-impact-wrench-bare/5445j
On this occasion it's for the gear mechanism attached to the gear selector. The bolt should only be tightened to 23Nm with a bit of threadlocker but even with quite a lot of force it's not moving. I'm hoping that the 'impact' from an impact driver will break the seal without any damage to the hex. Have just ordered an 18v Hitachi - on the basis that I have a Li-ion battery that'll slot in which saves half the price
Try sympathetically tightening it first. Otherwise get a bit of load on the ratchet and then tap the bolt. Single hex spanner or socket only btw. Don’t use an impact ratchet IMO.
23Nm is not a lot... It’s probably the Loctite that’s holding it. I’ve just rebuilt the bevel drive on my old BMW, try getting this bugger loose....200Nm and BMW’s special nevergonnabudgeagain Loctite".. I needed heat, lots of it, to melt the Loctite...you’ll probably find if you give it a decent warm with a gas gun you won’t need an impact wrench. Give it a go...good luck Poucher
Bought one from machine mart. I only use it for getting nut and bolts removed, not for refastening...One of their own makes (Clarke i think) works fine. Handy for removing the rear wheel nut...
I bought a Ryobi 3 speed impact wrench for stripping down an old yamaha engine that had stood for 10 years. I already have other Ryobi tools so have the compatible batteries. It made the job a breeze especially on crank and clutch bolts, I was surprised how convenient it was, no damage to fasteners. I did not have to use my large breaker bar once. I have only used it for the bigger tighter botls, but helped even with the smaller stuff. It made light work of crudded up bashed phillips head bolts in the clutch, so I would say that any are worth it especially for tricky stuff. Mine cost about £100 without the battery.
