Paddock Stand Bobbins Mk2 650
« on: August 11, 2017, 12:17:30 AM »
Hello all,

First post and hope you can help please, I am trying to find out the bolt size for paddock stand bobbins. I bought 8mm and 10mm ones, the 8s were too small so must be the 10s I thought. The 10s screwed in a turn or two by hand, albeit a bit stiff. Got allen key and turned them in another turn or two. The bolts got tighter too early to screw all the way home. Removed and threads on the swing arm side appeared shiny and slightly chewed up. Can anyone confirm correct size and thread pattern. The ones I have don't say what the thread pattern info is. Anyone know how many threads there should be on the correct bolt maybe? Have searched here and elsewhere and cant find definitive answer.

2012 Versys 650, a Mk2 I believe.

Thanks,Creasey.

 I can't answer your question directly, but I do know that those threads on the swing arm get plugged up with dirt and other misc. crud pretty quickly. I always give mine a shot of WD40 before turning in the bolts that I use to support the rear end. There have been occasions when I have had to turn in the bolt by hand until it sticks then take it out again, blast the hole with more WD40, turn in a little further etc. Do this until you can feel the end of the bolt with your finger, coming through on the other side. Those bobbin holders are a bit flimsy imo.

 I'm pretty sure you're right about 10 mm bolts for the Mk2 but I don't remember the pitch.
 Worst case scenario you might have to tap the threads if they are chewed up, but that's not desirable as they are alumin(i)um and wear easily.

It is not a standard M10 with a 1.5 pitch, which i guess you have.
You will need M10 with a 1.25 pitch.
I hereby state that Kawdog is a fantastic person to have on your motorcycle forum.
His comments are (usually) equally as valid as all other available comments and each is (usually) perfectly reasonable. I applaud (almost) all of his opinions!!

Hello Uralrob and Stewie,

Thanks for the replies. I cleaned the swing arm threads and same problem but good suggestion all the same. I hopefully will get 1.25 pitch ones tomorrow, go home, fit them and get rear wheel off and then get back to shop to get tyre replaced.

With regards to bolts, if a bolt says M10 with no further info you can assume it is the standard 1.50 pitch, aka coarse. It will only specify pitch if it is not the standard 1.50. M10's come in standard, fine 1.25 and superfine 1.0. Well thats what my research threw up.

I went to many hardware shops trying to find a fine or superfine M10 bolt to verify which bobbin I needed but they are generally not to be found here in Ireland. I intend leaving the bobbins in full time with the help of some thread lock. Also aluminium is prone to warping a little if you were to regularly tighten bobbin bolts, this might cause another problem down the road.

Oxford bobbins look a good bet Creasey, if you can find a stockist. They list M10 fine (1.25mm pitch) and normal M10 (1.5mm). A lot of online just list M10, like the R&Gs.

It's an odd one this because i had to contact Stevie Mann ( the Bike-Jack bloke, good bloke) about the supplied threaded pins. I received M8 and M10 but my MkII has
M10 fine like yours, Stevie's has M10  :033:
