OK so i have really messed up again :'( :'( :'( :'( :'( :'( :'(
Snapped a front mud guard bolt and i really am annoyed - was using a torque wrench to get it to 7NM but it just span round and round then snapped....WTF can i do about this!
yes i can ride without a fender but want to fix it....OMG

get drilling!
-
i am thinking left had drill bits might be best here after what i learned when the exhaust studs snapped.....
-
get drilling!
As the man said.
That's one bolt I would never have thought of using a torque wrench on. Maybe something to be said for "Feels about right".
-
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?
-
so yes wrench was in NM ( other scale is inch-pounds..)
and i was using copper grease...
I really am perplexed as to why it happened, but we all know its usally operator error....so i cannot figure out what i did wrong!

-
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
-
This was put on a previous topic on here and may be of interest http://benmlee.com/4runner/threads/threads.htm (http://benmlee.com/4runner/threads/threads.htm)
But for those bolts I always go by feel anyway.
-
hmmm i think i may be spending my weekend cleaning some bolts and re-doing them without the copper grease.... :lol

I will say again, personally i think Copper Grease is great stuff BUT these thoughts also make sense too, so for lighter torque settings use the "nip up" technique, but for heavier stuff use oil.
I handle film cameras on a daily basis so i nip up tiny screws that if you blink you could drop them and never ever see them again, so i've never been heavy handed anyway.
-
thanks, i think for the high torque bolts i will clean them and torque them dry.....i.e. suspension clamps and axels etc...
other bolts i will just get used to nipping up...
-
OK so just cleaned some bolts and reset them, i actually used no torque wrench for the first tighten and went by feel on the Upper and Lower yokes for the forks, and the axel and pinch bolt, turns out by feel it usually pretty close to the suggested torques.....so happy with that...

Use engine oil rather than dry, something's better than nothing, and it won't affect torque settings at all.

If grease affects it I'd say oil or any other lube would have the same affect. Is it affect or effect I can never remember :lol

Looks like, you are in Aus to long, its affecting your brain :lol
-
:lol

to affect (vb)
an effect (n)
or is it the other way round :rolleyes

ah that explains it (if it's right :lol). thanks I'll be able to sleep tonight
