Shock – Horror

[Blue_SV650S]

Fitted my ZX636 shock (and short dogbones) to my curvy trackbike today. I was a bit concerned with the side to side play in the ‘fork’ bit of the shock where it joins the linkage and how there is literally a piece of papers width of clearance between my nut/thread end and my dogbones!! :shock:

It is not wear in the linkage, or slop between the fork and the metal tube bit (I did put a washer in there as the fork width is a mm or so wider than the stock one). Also I cut a bolt so was no longer that was the minimum necessary to fit my nylock on, so it is not like I have a mile of thread sticking out. And it is still a nats away!!! I can see no other way of doing things, but it does seem awfully close and with the sideways ‘slop’ I can see that at a minimum the nut might rub the inside of the dogbone, at worse ‘catch’ if it ever clears the dogbone when the suspension moves? :-k :smt104

The stockshock didn’t require a nut as the fork was threaded so there was never a problem … but with the ZX6 shock requiring a nut, have others found it to be a little tight??

She's a tight fit mate but it works. You may have to take an angle grider to the outside of the offending nut to just make that extra couple of mm clearance for peace of mind.

That's what I did with the Gixxer shock that I fitted. Just ground it down by a mil or two just for reassurance.

Does shound like it is tight one .... at least I am not the only one!! :?

To be fair the thread isn’t really protruding at all … if I took any thing worth talking about off the nut it would be the nylock part … and that would be defeating the object …

I’ll run it, but just keep an eye on rubbing/wear. Does the suspension ever travel enough that the nut could get trapped under the dogbone (and hence catch and edge)??? Or is my worst case here just a bit of rubbing?

Can you turn it around so that the bolt head is where the nut is now, and then grind it down a bit instead?

Say what now?? :lol:

If I was to put the bolt in the other way round, then I get the same problem, but the other side … the head of a bolt is thinner than the nut, especially as I need to be using a retaining nut (nylock).

The shock is not dead center between the dog bones, there is more space on one side than the other. I did not have to cut any bolt when i fitted mine.

Also do you need to use a nyloc nut. Would an ordinary nut with Loctite thread lock not be as good with a lot less space used.

I didn't know Sean Connery was on this forum!!!! :lol:

Sounds like a good idea - Zx636 shock on the SV ... mmm ...

... my mates got a zx636 :twisted: :wink:

I used a couple of washers to space out the dog bone on the side where the nut is. Did the trick for me.

[Blue_SV650S]

TSM – Which side is you nut? I found the whole fork bit could slide side-to side, therefore if I slid to the left I would get more clearance, but that isn’t the point. So basically I am not sure the side the nut goes on makes any difference??? Either way, which side is your nut?

Timwilky – that is an alternative, but bearing in mind how crucial it is that this bolt stays in place, I am not sure I’d put my faith in threadlock.

Black Rider … was a slurring me words again?!?! :lol:

From your pic you seem to have a pointy, the ZX shocks are not what you want for your bike, I think it is the GSXR shocks that fit yours (do a search ion here, someone has a compatibility list).

Jase22 – I did consider that, I actually put some spacers in, but I think they were too thick as I couldn’t do the nuts up … some penny washers might be a better idea … I think of all the options so far, this is the one I would feel most happy with (unless putting the bolt the other way does indeed give more clearance??)

[Jase22]

My washers were probably about 1mm thick if that helps. Don't know which size they were, just "borrowed" them from my dad's stock of nuts n bolts n stuff he has in little boxes in the back of his garage, aren't dads great? :D :D

I did the same as Jase. One washer inside on each end of the right-hand dogbone, shock lower bolt cut to exact length with the nut to the right. I used a normal nut with threadlock because the original one was chewed up at the time of removal....oops!

Standard M12 washers are about 1.5mm. :thumbsup:

Cool, I'll get down the DIY shop and get some M12 Penny washers :)
