Bolts can shear off... Mad

Damn torque wrench never 'popped'.

Lower triple tree...both of them snapped at the same time, ABS sensor side...got one out with a pair of vice grips. Not enough of the other protruding to do the same...

And on Friday of the start of Memorial day weekend just isn't a good time for this to happen. Luckily, my agent at the stealership went up to the shop, and retrieved two hardened M8x1.25 bolts for me, and didn't even charge me.

Whoo hoo!

So now I'm off to Autozone for a drill and tap set to remove that one...and a new torque wrench.

I usually start torque settings at about half and work my way up.

I have, on one or two occasions, forgotten to reset the audio visual pin in my tension wrench - embarrassing, it is Embarassed

I've been wrenching my own vehicles since age 18 and have very little use for torque wrenches. Gut feel works best IMO. On a K, the only place they're really needed is the clutch nut and pivot bearings. Just my .02.

U SNAPPED 2 BOLT ON THE SAME SETTING OMFG.....

just busting ur balls...

Here is the rule of the thumb ... start at the lowest setting and work up.. most of the cheap china click torque wrenches are not caliabrated at all .. the best ones to buy are the BEAM style.. you can see how much is being applied. my dad worked on and flew the OH 58 ( MASH style) Bell helio's during the Korean war. He also taught the new WRENCHES proper procedures when working on the aircraft.

Also SIZE dose matter do not use a 1/2 inch when all you need is 3/8.. you will over stress the threads before you ever get the wrench to pop..

MR. Duck NO disrespect here but Gut Check style wrenching is really inappropate here. How about you ask the "WRENCH" that installed that aircraft engine on the Aircraft you just boarded ... YO.. did you GUT check that engines' mount bolts and the main hub lock nut for the landing gear tire assembly.

I've never had any issues and I've been wrenching that way for 150,000 miles or so on bikes and Dog knows how many automotive miles.

On the K75 I'm building from scratch I will use a torque wrench three times:

Frame bolts.
Clutch nut.
Swing arm pivot.

I am VERY confident that the bike will not drop out of the sky.

Once I've got a few miles on it I'll check the valves. Since the cover bolts are easily stripped I'll use a torque wrench on those too.

I wasn't necessarily promoting it. If you guys want to torque every bolt on your bikes that's cool with me.

By the way, my undergrad degree is in Civil Engineering so I understand materials science, metals, friction, stress, strain, shear, Mohr's circle, blah, blah, blah.... Precisely torquing every bolt isn't really necessary IMO.

Torque wrench, schmork wrench. Laughing

Just my .02.

Anyone know the torque setting for the left side fairing mounting screws? Mr. Green

15 FDs. FD is a Foot Duck, ie 1 FD is the weight of one duck at 1 foot.

If the duck is flying at the time (FFD) you need to double it, ie 1 FFD = 0.5 FDs.

Don't get this confused with the other measurement an FF which is a state of not caring, commonly used in statements like "I couldn't give a FF".For reference, 1 FF is a variable, could be anywhere between 0.1 FDs and 1000 FDs depending on how many beers you have had. Using FFs for fairing screws if fine, just don't use it for clutch nuts or your own nuts for that matter.

Ah Shogs, you are too kind, alas the tyranny of distance will forever keep us apart, oh I nearly forgot, my uncurable misogeny won't help either...... Very Happy

FD, doesn't really matter for K11's but I have it on good authority that NASA only use Austrian Wood ducks fed on a diet of Venzualen Beaver cheese between the hours of midnight and 4AM. The British can't do this as they are always fresh out of Venezualan Baever cheese, apparently the cat ate it.

Seriously though, I agree, mechanics of planes had better be using a whiz bang you beaut digital totally accurate TW of some sort or I won't get on the plane. Not sure that applies to home mechanics on road vehicles though. I subscribe to FDs theory, except for mission critical areas, and on top of what is mentioned above, I'd add anything that has bearings, ie big ends, head bolts, cam shaft etc etc.

But for general exterior stuff like fairing mounts, nah, do it till it feels right. But maybe that's a learned skill. 20+ years of fiddling with VWs have taught me when to not overload a bolt especially in the engine. They are very unforgiving!

This was some funny chit! Laughing

Good on every one for sharing.

If your using a torque wrench, make certain it's calibrated correctly. Otherwise your just as well not using it.

I was a tool & die-setter for some 8 years, been wrenching stuff for longer than that. I have an 81 R100RS with 133,000 miles on it, yes most all of the miles are by me. I have a feel for what's tight enough. Not everyone does. That's OK, we are all differant.
There are some fasteners that just must be torqued properly, there are many more where if you have the " feel " it's not really a requisite to get the job done.
Use your best judgement, it's your ride, you should know your skill level both riding and wrenching.

I like my duck grilled, over charcoal please. But not the Drake. Wink

Nah, you're all full of duck***t (similar to bovine effluvia). As Jim (I think) said, I know the figure but if I told you, I'd have to kill you. One thing, though. I can assure you the figure is NOT 2 grunts and a fart!

There used to be a humor video out there somewhere. A guy in his shop looks up the torque spec for a lug nut, puts the tire iron on lug nut and then pounds it with his foot it 42 times. Laughing
