I'm about to change my rear sprocket on my multi Dvt, it looks like the big nut on the sprocket side has to be removed, could someone tell me what size it is & also would a normal common hex socket do the job ? Many thanks Steve
55mm double hex , the one I have is a 3/4 inch drive and I have a 3/4 inch drive 3ft breaker bar so no flex ... just cracks em off . Bare in mind when you purchase the socket that you have the breaker bar to fit the socket drive . Hear lots of folk struggling to get them un done ..... right tools for the job makes it loads easier
Well what's a standard socket ?, a single hex will not go on a double hex , bought mine off eBay ... just get a quality one not some cheap chocolate type
Ditto what Lee said. I've tried using a 1/2" drive with a 3 foot breaker bar and there is too much flex to do it effectively. Just out of curiosity, what are you changing your sprocket to and for what purpose?
I see your nuts and sprocket nuts are also discoloured too - mine is normally used in dry - cleaned every trip and I spray everything with Silicone as part of the cleaning - but has gone like yours. There are special sockets also available- as well as the normal Bi Hex sockets - these are all 1/2" drive - these normally have a spigot that goes through the hub so you have better guiding and centralisation - I bought mine from Moto MFG in USA - but are available in Europe They then cut a socket in the middle for the front axle nut which I think is 30mm on Multi but 28mm (odd size) on the scrambler. If you use 3/4" drive to break it - you probably need a 1/2" version for torque driving it back up - unless you have a 3/4" torque wrench. If you buy the special sockets - make sure you buy the steel version not the aluminium.
Changing my sprocket to a 42 tooth I went to Riders Ducati earlier , as I was too impatient to order from eBay & wait for delivery, very helpful chap at riders sold me an Oberon socket, bit pricey at £35, but hey ho, I'm itching to get the job done Steve
BTW sprocket side came off easy on mine, wheel side...totally different story. Grab an impact gun if you can
I'm not worried in the slightest about longevity, I won't be removing the nuts that often at all. Steve
A lot of impact guns won't touch that amount of torque. When I replaced my rear tyre I had to take it to a dealer who had to get a T-Bar with a 4ft extension on either side and had two blokes do it. They also had a nightmare re-torqueing it.
I managed to get both wheel nuts undone, with quite a bit of difficulty ! There was no one available to put a foot on the rear brake for me, so I cut a small piece of ply wood, and wedged it between the rear brake pedal & the pedal stop, that wasn't applying quite enough pressure, so I used feeler gauges to take up the little bit of slack, while I used my hand to push the brake down as far as I could I then straddled the bike backwards & pushed my foot down as hard as I could on a long breaker socket bar, the nuts were stupidly tight!! I then tightened them up to what my strength would allow, I didn't torque them up, they are flat bearings, so in my opinion just need to be bloody tight, a good strong arm will suffice The spring clips will stop the nuts coming undone.
So you started out not knowing how to measure across the flats of a nut, and now you know more about required torque settings than the very clever people who designed the rear wheel retaining mechanism. Best stay alert for any signs that the back end feels a tad vague, and pull in pronto:flushed:
Are you one of those people who picks holes in people !? I notice you didn't offer any assistance before ! That's my opinion above, if you don't like it or agree with it, that's your perogative, no need to TRY & be a smart arse.
Just stating the facts, along with a helpful tip I avoided offering further advice as you clearly know best A bit like the info from those who offered advice on why not to buy an aluminium socket, which you ignored with a wave of your (hopefully powerful) hand And by the way, plenty of cases of nuts backing off despite the spring clip, but you knew that didnt you?
Bit harsh. Race paddocks are full of bikes with rear nuts fitted without torque wrenches. I have never hear of a ducati rear wheel losing its clip and coming undone, after 15 yrs around them. Quite the opposite, they always seem to tighten on. Twin sided however, seen a d had that loads of times
Regarding the socket, I was grateful for the advice I gained, as I always am on here, and if you took the time to read what I posted, I pointed out that the alloy socket didn't cause me concern, as it will have very little use. If it puts a grin on your face, yes I knew that, & what ever else you want to throw at me Your obviously 'one of those people', every forum has at least one.
I would suggest not "plenty" but exceedingly rare. Unless you have references to 55mm nuts with properly installed clip coming loose
