i am thinking left had drill bits might be best here after what i learned when the exhaust studs snapped.....
it was a cyclo-torque wrench specifically for low torque - and the service manual does state 7NM....so i figured i would do it right :\
7nm new, as above "feels tight enough" is what id use for this.
Relief.....manged to grab the tinest piece of it and it came out with ease with a pair of neddle nose pliers!!!!
WOHOOOO!
I might just get this back together - eventually!
Are you sure the torque wrench was set to 7Nm and not set to 7lbf.
Were you using copper grease?
More people are born because of alcohol than will ever die from it.
lucky then!
maybe it was a worn bolt
damn lucky - the tinest bit of thread left - i would like to know what happened - it felt like the bolt was twisting when i realised what happened.....exactly the same as the exhaust stud feeling thats what i thought oh no.....and stopped.....but it was too late - literally pinged off....
it may have been done it too tight before and you just helped it finish itself off.
yes i like that idea - it was like that when i got there - that will do nicely for this one :b
7NM would be for a dry bolt if you put grease on then 7NM on the torque wrench would be greater due to the lower friction due to the grease if that makes sense.
Need to reduce the dry torque setting by 20% or more for greased bolt but can vary a lot depending on grease and materials. Sometimes a low torque setting is given then an angular measurement given to avoid the problem so you tighten to 3nm say and then tighten another 30 degrees
Jules-C/Andy FZS - understood about the need to consider the effect of grease.....never considered it!
How would you reliably figure it out - is there a chart that shows how certain greases affect the fixings?
So can i ask - on bolts such as the suspension clamps, if they are greased - is that advisable or not, i am going to be doing a once over soon before the MOT, not sure wether i should copper grease all threads or not?
Sorry I can't really advise on % of torque if greased. I often put grease etc on bolts and seldom use a torque wrench. I tend to just nip things up until they're tight dependant on size. Not really helpful I'm afraid.
nah its ok m8 don't expect it, i have copper greased the threads on the yoke bolts and tightened them to recommended torque, will re-consider
