Just taken my bike for new sprocket & chain, been called by mechanic saying he can't remove the sprocket carrier nut. I believe this is a common problem on theses !?!? Any usefull tips I can pass on to him ???
Did mine about 2 weeks ago. Got mate to sit on bike holding brakes on hard. Used battery impact gun and it shifted. Torqued back on but ensured plenty of anti-seize compound on thread before threading back on. Same process as above to replace. Bike was on ground too. Help to stop wheel turning If he's trying to do it alone he might struggle. I didn't put bike in gear as I think this just loads the gearbox/engine when trying to spin it off. Impact gun definitely easiest option.
Air gun was useless for I’ve got one too. Tried in past for wheel nut, hence above comment. Unless you have high rated compressor etc, you’ve likely no chance. I now have corded high torque and battery hi torque impact guns. Both 350/400nm capacity. He should manage but an assistant on bike and brakes will definitely help.
I've got a DeWalt DCF899N Impact Wrench, rated at 950 Nm, and it wasn't that easy to get the sprocket side nut off. It would definitely help having someone pushing down on the rear brake and the rear wheel.
Deffo need a rattle gun, I tried with an air wrench but no luck, thinking either the gun or the compressor are getting tired, had them nearly 20 years. I ended up having to borrow my sons snap on 18v jobbie. It was a piece of piss, all I had to do was hold the wheel and in a few seconds both the 55's were undone. A little clean and anti sieze on rebuild and torqued correctly.
Absolute key is someone sat on bike holding rear brake. Have seen truck air guns and two lads on a 2m scaffold bar fail until someone helps out as above, then; off in a jiffy.
Interestingly I'm now struggling to get my sprocket side 55mm off even though I had the hub etc out a couple of months back no worries. Well I had to use a breaker bar with an extra length of scaffold pole to remove them. But now the sprocket side just won't budge. Have to admit to not using anti seize on reassembly so when I get the bugger off this time I'll make sure I do that. I've tried a friends milwalkee impact gun but no joy although I don't think it's a high rated one. If anyone has a high rate one near Darlington I could borrow that would be great.
Thanks for the replies , guys. Passed the info on, so hopefully will get it off tomorrow with battery impact gun.
Owning a Duc necessitates having certain tools etc. An impact gun is so damn handy for other things too. There’s info on the forum about them. They’re not expensive. Type in a google search and you could have the tool necessary to do loads of stuff for less than £50.
If I could get one for £50 powerful enough that would be awesome. Dewalt etc are floating around £150 though which I wouldn't mind paying but I need to make sure it would do the job.
The high torque one DeWalt DCF899N steveb123 has is closer to £500 ?!?!? As you say, if going to spend the cash, then needs to do the job. Can't see a £50 one being good enough. If anyone has a decent one for sale, let me know. Ta.
Search Impact Wrench on the forum. Thread on this with good cost effective options. Edit. Here you go: https://www.ducatiforum.co.uk/threads/impact-wrench.73490/
Here’s my Clarke corded. More than adequate. Used on van, car, bike, timber framing. There’s one sometimes available from Lidl. Looks identical even down to spec list. Just different name and packaging. Think it was £38.!
I haven't had need to take my back wheel out yet. When I do, I have an 18 volt impact wrench to try but I will not be torquing up to the spec'd value again. It will go back up tight but not to the zillion footpounds recommended. The clip will stop it coming loose.
I use torque wrench. I had a Ktm 1290 in the past. Had puncture, got it fixed, put wheel on. Tight? Yeah, that’ll do or so I thought. Went out. Hour or so later thought I had another puncture. Got off, checked, no puncture but nut was loose only the clip kept the nut/wheel from coming off.! Takes a few minutes more but for my own piece of mind, always torqued.
I bought one of these to undo the wheel nut on my Monster 1200. https://www.ebay.co.uk/itm/Heavy-Du...=161945783962b56a88f592ee41c1afec9b7850564865 Took a while, bit it did the job. Can't say whether it would do the other side, but it might be worth a try. I can confirm a long breaker bar and a bit of scaffold works if you have someone to sit on the bike and hold the brake on...but only just.
Here’s link to a Clarke copy. They’re all likely made in the same bleedin’ factory! https://www.manomano.co.uk/p/heavy-...rive-and-4-sockets-450nm-torque-1010w-6630638
