I was thinking of putting this under Technical .......... but this will do ........
Gets flack for bad - mouthing Stuart Fillingham ........ you decide if he goes too far ....... Whatever , I don`t watch Fillingham that much ....... he tends to be one of those pious types , although his drone shots are nice ..........
Anyway , the point he makes about torque wrenches is nonsense , obviously ................. although you could argue one click is enough .............. ( clunk click every trip , as Jimmy Saville used to say ) ......but more than one will not continue to tighten the nut , as he claims .
I think Clem brought up the subject of torque wrenches , and the need to re - calibrate them , a little while ago .....
I have two ........ one a fairly recent purchase which reads up to 25 NM .... and another which I`ve had for ages ... ( a Norbar ) ... which reads up tp 150 NM .
The Norbar I have never had re - calibrated , although it must now be about 45 years old ......... probably a good idea to have done , but there doesn`t seem to be anywhere nearby who would do so ......... and it`s not really the sort of thing I would want to post off for someone to do .......
I would rather witness the re - calibration being done ....... rather than risk someone sending the thing straight back having not touched it ........ " Yes , it`s fine now ....... here`s the certificate ...... that`ll be fifty quid please ......... Thanks sucker " ..........
What I do with both is unwind them back to the lowest setting when not in use ..... to save putting strain on the spring for long periods of time .
As it mentions in this video , there are variables at play ( literally ) in any case ......... probably down to and including the way you hold the thing when using it ...... and whether the thread is dry or lubed ...... and ...... and ....... and ..............
One other thing I am wary of is following manufacturers torque settings to the letter on smaller fasteners in aluminium castings ......... tightening a rear axle nut to 150 NM may be all very well , but if the recommended setting is , say , 15 NM on a smaller , more fragile fastener , then I will aim for something like 12-13 , instead of the recommended 15 ....... in deference to those afore - mentioned variables ........ and especially so if it`s any older machine which has already seen more than it`s fair share of fastener action ..........
BTW ....... In a magazine article recently , where someone was prepping a R7 ......( the twin , not the homologation special ) ...... for race use , it was claimed that it is not unusual for new bikes fresh off the production line to have fasteners either tightened with the aid of a breaking bar ( apparently ) ....... or little more than finger tight .........
A slight exaggeration maybe , but not always fastened to the spec mentioned in the factory manual .......
This would apply to the motor and various chassis parts presumably ......... things like wheels and handlebars would have been put in place by the importer ........ and therefore be ok , you would hope ......... although I would still want to double check things like that , including brake calipers , before venturing too far ........
