Attempting to swap a new stand but ran out of time due to this bolt.

Front bolt turns with a lot of effort but does not come out. I had assumed a simple threaded hole but it is moving like there is a rotating nut on the other end.
The second bolt is out, m10x40 ish, nothing special it was also tight.

They bolt onto protruding boss'es from the end of the gearbox. If the first was going all the way with a nut then it would be a bloody long bolt. Any ideas?

It wouldn't be unknown but unlikely for a sidestand mount. If it's a through bolt then there will be a place where it protrudes the other side of the engine, plus there will usually be a tell-tale bulge in the casing full width. Have a look directly opposite and if there's a nut, put a ring spanner on it. Turn the bolt and see if the spanner moves.

Taking a stab at the year, but there's no really long bolt on the sidestand.

Just been downstairs to have a look at Mrs Stinkwheels CBR600FV (not injection but I think it's the model immediately before yours and has the same alloy frame).

I'm presuming you are meaning the frontmost of the two bolts that hold the sidestand bracket to the bike rather than the bolt that holds the stand to the bracket.

Looks like it's a huge long bolt that also holds the bottom casting (rear cushion) for the monoshock assembly to the engine. If so, it goes right the way through to the other side of the bike and has a locking nut on the other side.

I'd have the bike on the mainstand and chock under the swingarm/rear wheel to stop the whole lot dropping and pivoting out of place before you remove the bolt. There are two spacers in the middle too so keep an eye on where those go. I could see this lot being a total sod to fiddle into alignment to get the bolt back in again. A lot of podgering and risk of trapped fingertips.

If it was me, I'd chock the back end so it can't drop. Then I'd remove the nut and drive the bolt all the way through from the right side of the bike with a long 10mm bolt or bit of bar so the bit of bar replaces the original bolt and keeps everything aligned. Then I'd change the stand and drive the bar back through the other way with the original bolt. Nut back on, job jobbed. Lots of copper grease on the bolt.

If you're struggling to see which nut, get an assistant to turn the bolt while you look to see which nut is turning.

Bolt number 15 on this diagram.

Thanks for that, Im going to leave it well alone, itll probably be seized to a steel spacer and have to be cut off or something silly. Ill try to torque it back up just incase it loosened.

I will attempt the pivot bolt instead.

If it's turning the nut, It can't be particularly seized. If it was going to seize anywhere, it would be where it goes through the alloy in my experience of such things.

Really easy to check. Undo the nut a few turns and give it a tap with a hammer (it's a flange nut so you can use a socket and extension bar to get on it). See if it moves. If it does, it's all but out, with a potential for having to spray the middle with penetrating oil and tap it back and forth a few times.

Or, as you say, just change out the stand itself, although if you're chainging it due to wear, the bracket part of the pivot will be just as worn as the stand part. Wear safety glasses when you put the spring back on.

Makes you wonder why they put the bolt in from the stand side. If you do get it out, put it back in the other way so all you'll have to do in future is remove the nut to get the stand off.

They do a lot of that kind of shit. I think honda do it on purpose to put people off working on their own bikes. On the CBR, one of the shock linkage bolts can't be removed from the left side either until you've freed off the whole linkage and ytou'd have to pre-assemble the linkage with that one in place first to reassemble it the same way. It slides in freely from the right.

I had a similar thing on the VFR750. One of the shock bolts through the swingarm cannot be removed without first removing the mainstand but if it was in from the other side, it could. So first time you take the swingarm out, you have to find a way to prop the bike up without the mainstand. Neutral It's not really obvious so you'd generally have removed the rear wheel and most of the shock linkage -as I did- before you realise this is the case. I was not amused.

I suppose it's a good way to check the veracity of a seller claiming to have serviced the bearings.

The FJR is also similar, in that you cannot remove the centre stand without cutting bolts that Yamaha put in the reverse way. And again it’s possible to see if the swing arm has been serviced as new bolts are then replaced in the centre stand the other way round.
If you get my drift!
