Hi guys,

I'm sorting out my bike before I bring it back out in the fresh air within the next two weeks. Next thing to do is, put on the R&G engine covers, and for that the instructions say I need to tighten the bolts to the correct torque.

Had a look at this manual for a 2010 R6 [url =https://www.manualslib.com/manual/893275/Yamaha-2010-Yzf-R6.html?page=69#manual] Link[/url] but I'm guessing its roughly the same for the 2017 model.

Thing is, I'm not sure with torque wrench to buy and what the torque number correspond to on a torque wrench (as its nm on a wrench right)?

Sorry for the ignorant question but I am trying to learn.

Everyone does some time, don't worry smile

Looking at the values in that table, 5Nm and 2Nm are right on the limit of what you can really read with a torque wrench. I'd just do it by hand and gently nip them up.

If you really want to buy a tool for it have a look at torque wrenches for pushbikes - some of them will go that low.

I just bought this one the other day.

Seems very well engineered, and better than I could buy in a shop locally.

I purchased this one last year and have been using it for various bikes bit and its been perfect. For the price you can't knock it.

Man, I feel like they're really hard to use and feel like I don't know what I'm doing, I may just go to the garage or just use a standard ratchet: finger tighten, then 1 and 1/16th turn with the ratchet?

How can they be hard to use? Turn it until it clicks.

Like how do I know the correct setting?

What setting did you use for your engine covers?

Just do them up gently enough so you think they'll stay.

1) Too hard and you'll break things (expensive, difficult)
2) Too soft and you'll need to buy a new bolt (easy)

Some things really do need the proper torque, others like that just need a little sympathy.
Remember how tight they were to undo? Tighten them up a bit less than that.

If you can use a ratchet, you can use a torque wrench.

  • Set the torque
  • Tighten until it clicks, beeps or the light goes red
  • Loosen off torque wrench if it is mechanical

1. Read the manual, look up online the torque you need.
2. Read manual on torque wrench.
3. Set torque wrench to that setting.
4. See other post.

As long as you don't buy some horrifically expensive, crazy one, they are fairly idiot proof. Think of it like a ratchet with a tightness indicator on it. The click etc. just tells you when to stop turning.

If you are still unsure Youtube on how to use one.

^This.
I bought a Halfords one a couple of years back for £50. It came with a calibration certificate & pretty good instructions & is nicely finished.
Cheap = false economy applies to most tools.

I would only add that Draper's mid-level torque wrenches (£30ish) are OK - my 3/8" one is still bang on the calibration (had it tested at a local place) and still nice enough quality being all-metal.

p.s. Am I alone thinking that if you can't work out an analogue torque wrench with it in-hand you shouldn't be using it?

Agreed. For very low values just tighten a bit more than hand tight. And buy a decent wrench not with a huge range, as they tend to not be very well calibrated at the low end.

I have the Halfords 3/8 one as well. Not cheap but good quality. Very simple to use. I only use it for critical fasteners...

Funny, I bought R&G engine covers for my gsxr1000r and then I bought a torque wrench (need 10nm). The hope is I do the work myself and money saved on a shop doing it for me will pay off the wrench. :-)

And when using a torque wrench apply the force slowly and evenly as it nears the desired torque.
The amount of muppets that do it like they're on the clock just shows how clueless they are, often going straight through the click for the setting and beyond (tyre fitters all the time)
And being smooth ensures consistent results.

I have a Gedore (decent one) for 2-25Nm as those settings are more difficult to achieve, and a Draper Expert (average low) I bought probably 30 years ago for 30-140.

The narrower the adjustment range the more accurate the wrench is likely to be for a given manufacturer.

Usually 8Nm for the 6mm case bolts into aluminium.
And 10% lower torque as a rule on oiled or greased threads

Thanks!
R&G wrote 10nm, but I wonder what the official figure is.
So, you suggest 7nm?
