Head + Rocker cover torques...
Bryanj:
Havent got time to look it up for you but try looking for wheel torque and detached wheels on HGV. They usually discuss oiled or not
Laverda Dave:
Interesting point you've raised Nigel. I always brush copperslip grease on all threads (although not big end bolts) to make it easier to remove the bolts should I have to. I do this through bitter experience stripping threads trying to remove bolts that have siezed through steel/aluminium reaction. I didn't know this affects torque figures and will work to this in future. Thanks for the information.
Lobo:
... the stuff you learn on this forum... so many clever folk here.
Question Nige.. will the threads maintain integrity if never torqued beyond the book figure... or will repetitive torquing eventually take its toll?
If the former, must we assume that over-torquing regularly occurs?
And as Harold asked.. is it good - or poor - practice to slacken any nut / bolt slightly before re-torquing it?
Cheers.
Simon
Bryanj:
As a time served engineer on big stuff to guarantee correct torque you should work in stages and on the last stage DO NOT STOP between starting to move and attaining required torque as the friction between nut and washer/head frequently takes more "torque" to get movement than the static fastner is at.
On the re-use of studs/nuts/bolts as long as you stay within the "elastic" limits of the metal involved you can use them till the thread wears out, this is why on most modern car/truck engines bolts have to be changed every time as they are not "torqued" but tightened through a set angle after initial seating which takes them very close to the "elastic limit point". Old Triumph motorcycles used to specify a "stretch" amount on big end bolts rather than a torque.
Are you now all suitably confused?--------- Good cos Swansea just sent me a letter telling me my licence is to be retuned to me in another letter so when it arrives i can go back to work!!!!!
Nurse Julie:
Great news on returning back to work Bryan.....keep healthy now x
