Tightening chain

[Draper]

Do you really need a torque wrench for this?

And if so how do they actually work and how many snutts are we talking?

Chain is as baggy as anything atm

Also is it a rear stand jobbo as i have just bought one of those cheap cup ones, and i'm quite impressed at its stability

a thankyou

Not really, just rough guess at how tight the axle should be. Don't check tension on a stand, it's meant to be done on the sidestand.

+ 1, can't remember the last time I used a torque wrench on the axle of an SV.

True enough guys but we have to assume people reading are clueless as to the tension required. I don't use a torque wrench either but that's because I already know how tight it should feel before I start. Others may not.

If your not sure I'd do it as per the book until you have the experience. It's always good to have a torque wrench anyway. :wink: May as well use it to be on the safe side.

Yeah, the offical torque for the axle is 65Nm on the wrench. Having said that, my mate uses an adjustable spanner on his bike. He tightens up the axle with the spanner then knocks the spanner with a hammer a few times - done!

:cool:

Is it different on the curvy, the pointy is 100nm?

yep they are different.

Torque wrench is best, but just use a short ratchet and do it up to FT, unless you is a right beefcake or a right wimp, you won't be far off with FT 8)

FT solves so many of those tricky questions. :lol:

I have a really reliable torque wrench


It has a name...

...Dad

The SV axle is done up to "tight and a bit more tight"

So a pointy is done up "tight and a bit more tight, then a fair bit tighter"? :)

I'd advise someone new to get a cheap torque wrench (however inaccurate they might be). 65nm isn't really all that tight, with a long wrench it would be very very easy to over do it.

[Bibio]

if you are asking then (without me sounding rude) you have no idea of 'hand tightening torque' it takes a few goes to get to grips with.. so i would suggest getting a cheep torque wrench to begin with.. in time you will get to grips with how it should 'feel' when tightening things.

best of all is getting someone to show you how to adjust your chain.. ma bee ask if there are any local sv650.org members near you who would be willing to show you.. you never know you might end up with a nice new friend...

ok a couple of youtube vids for ya...

cheers for the help guys,

with tightest point in the middle and adjusted to correct slack, theres some other parts of the chain that are much slacker, ~35mm. Is there a way to get it all evenly tight or is the chain buggered?

[Biker Biggles]

That sounds OK.Chains do wear a bit unevenly so you get "tight spots".The clue that it is wearing out is that you have to adjust it much more often than normal.

You ride a curvy, so "tight and a bit more" for you/your dad is 65Nm.

Nope, not at all.

My method is to use a tyre iron to undo the axel, then use that to put it back again. Just at the point where it starts being fairly difficult, I stop. Out comes the torque wrench, set to the correct value, push down - it generally rotates about 1mm, and click, done.

So for me, it's "tight and a bit more" - but that's 100Nm. Maybe I'm stronger than Alpinestarhero's dad. :D

Haha "Nope, not at all".
Let's argue about how to describe approximations of tightness using the words bit, more, and tight! :)
"Gee you're right, I was way off" :)

If you're guesstimating, the length of your lever is a fairly huge factor, much more so than muscle. 100nm can feel pretty slack if you're at the end of a 3 foot bar- how easy would it be to overtighten without a torque wrench to check with?
Very.

Similarly just using a socket and your teeth will not give accurate results.
