  1. ive got a fairly basic Stanley compressor in the garage and was looking into getting an impact wrench for taking of car wheels and many for removing the rear wheel from my multi as will be easier to clean the wheel and the back end of the bike after cleaning the chain.

    Are there any issues with using an impact wrench for this purpose. I'm not techniqually minded and certainly am not mechanic so any advice welcome. I'll be looking at getting a decent socket as well rather than Oberon from what I've read on here and have got a torque wrench in the garage for ensuring real wheel is put back on right.

  3. The compressor needs an air delivery that will make the impact wrench work as it should. I have a large compressor that delivers 14 cfm and that will only just about work a moderate impact wrench.

    If your compressor is not up to the job then it will not allow the impact wrench to do it's job properly.

    I have the largest compressor you can use to run off 240 volt single phase electricity supply and as above it will work for an impact wrench for only a few minutes but consumes a lot of air and then loses all power.

  4. As Red says you need to check the CFM rating on your compressor and on the impact wrench. I've got a 12 CFM rated compressor in the garage which will power a few tools but won't touch the impact wrench I have. Getting yourself an electric Sealey impact wrench from Machine Mart is the best option.

  5. As an alternative, Dewalt do an 18V, 320Nm battery powered impact wrench. Does the car, the Multistrada and Diavel. I DO NOT however under any circumstances use it to do anything up with. Andy

  7. Whichever one you go for and especially if using for the rear hub, try to get one with a 3/4" drive. If you use it frequently, a half inch drive will sheer off. Had 2 sheer off now.

  9. Would someone mind having a look at the link and advising if my compressor is up to the task and if not provide a few electric impact wrenches that would suit my need sub hundred.

    Thanks

  10. Your compressor pumps out 180 litres per minute (according to the spec) which is about 6 CFM (according to google) so given the above, I suspect it won't be up to the job...?

  11. Thanks in that case would anyone be so kind as to spec up a breaker bar and socket for both rear wheel nut and sprocket nuts please. IdeAlly in 1/2 as just remembered I've got a 1/2 torque wrench in the garage which torques up to 210

  12. You might need a 1/2" female to 3/4" male adaptor then. Unless you have a half inch drive socket...

  13. Thanks have no sockets that size at all in bi-hex so adapter would be good idea for the torque wrench

  14. someone may correct me, but I'm sure the rear wheel nut has to be at 230 Nm and from my recent search this can only be done with a 3/4 drive

  15. I undid my rear wheel nut with a 3/4 breaker bar and an extension tube, which mad it about 4ft long. I did it up with a Teng torque wrench which cost about £130 (I think) Usually when buying tools I go for good quality, but with a 3/4" torque wrench its unlikely to be used very often.

    One tip i picked up, probably on here was to get the socket turned down so it wasn't as long, this has two benefits, it gets rid of the bevelled or chamfered leading edge and puts the turning or axis much closer to the nut, which makes the effort applied far more efficient making loosening the nut easier and less likely to spoil the nut.

    Having read a number of other threads (no pun intended) on this subject I was feeling fairly pessimistic when I had to remove mine the first time. Truth is I did it on my own in about a minute.

    Well prepared or lucky, id like to think the former but equally could be either.

    Good luck

  16. Thanks mate. Been reading around on Ducati forums and think I'm going to get a Clarkes electric Impact driver which is a 1/2 but get a 3/4 draper socket and a set of adapters for 1/2 to 3/4 amongst others.

    I'll use the Impact wrench to remove and use my current torque wrench to re fit both with the adapter and 3/4 socket. My torque wrench is only 210 but should be ok. Shouldn't it? Ha

  17. Incidentally does the exhaust need to be removed to take of the wheel and is there any requirement for someone to sit on the bike and press the rear brake/front brake

  18. No need for any assistance when using impact gun, an added bonus for me.

  19. What about exhaust removal?

  20. Personally I would spend the money on getting the right torque wrench
