The trouble is, if you exert forces greater than the torque wrench is calibrated for while undoing a bolt, then you will throw the torque wrench out of calibration.

Very true that's why we had a specialist company calibrate all our measuring equipment

I'm afraid you are incorrect there Dave (as are Dorset Bob, Mike Noc, ricardo65, Rogue & YorkshireGOC who "thanked" you). Out of curiosity I paid for Norbar to check my torque wrench immediately after doing this suspension job. It had not been "put out of calibration". I have been using it the same way for over 25 years.

I have never said that I do this or suggested that others do so.

On the contrary Bob, my tools are all in excellent condition thank you. As for my cars, they are lovingly maintained and repaired with extreme care using carefully selected components of the highest quality. My 75 has just celebrated its 22nd birthday and my SD1 is still on the road after 36 years so I think that shows that your accusation that I "abuse" my cars is completely without foundation.

Try a bit of free, creative thinking Bob instead of just following what other people tell you to do.

Rather than following what others tell me to do, I follow proven procedures and seek, and take on board, information from people who have the expertise and experience.

I do understand your feelings though.
As a young engineer (who thought he knew more than he did ), I remember having a conversation with an old boy at work on the subject of hydrogen embrittlement.
He was a very accomplished metallurgist and chemist and I was clearly out of my depth.
He gave me some wise words, that sometimes you just have to accept that things happen.
Use the skills of others who have the knowledge, and you will move on to develop your own expertise that others can draw on, in other areas.
About 10 minutes later, I realised that I had been given the most polite rollocking ever.

However, those wise words, more than 40 years ago, have stood me in good stead for my working life.

Good luck with your maintenance Simon and I will go away and lick my leopard's spots.

What you say must be applicable to just about any type of special ( Precision. ) equipment being used in the world.

For years I used total station EDM electronic measuring equipment and laser levelling equipment too.--All had to have specialist checking and calibrating.

All rather obvious really.---

Exactly so.---We are all always learning something new if we have active minds.---Personally I really enjoy learning new things.---I'm still trying hard every day to learn to speak and understand French.

Very true and equally applicable to just about anything you use outside of the design spec.

Linking spanners together is a good example of using something outside of the original design spec.---

We all do it at times don't we ???---

Simon all I can say to you is that if I had seen you using one of our torque wrenches as a breaker bar in my workshop then you would not be working there for long as we had very good quality tools and the did go out of calibration which is why minimum. standards set by mg rover said they must be checked every year

Whilst you lot have been debating the finer points of torque wrenches two things have happened:

1. Most poignantly I broke my torque wrench. I've never really used it as a torque wrench - more a breaker bar as I picked it up in a lightening sale on amazon for a pretty penny and have my Dad's 60 year old one I use for when it matters. It's on the highest setting but with 5 foot of box steel over the end trying to undo these wishbone bolts from the subframe the ring spanner held up (despite looking like a bend it like Beckham) and then the wrench went WHACK! and the innards fell out in pieces. Don't make em like they used to eh?

2. I bought a hexagonal socket for the rear bolt and after two days of penetrating oil gave it a good tug with the torque wrench, swivel head and shorter length of box steel for leverage. I could swear I felt it shift and was so convinced it moved I took the box steel off as I thought I was about to just unwind it but alas the socket had slipped

3. When the socket slipped it damaged the bolt head - only slightly and nothing to worry about just yet but I checked my extractor set just in case and I only have 17 and 19mm

I've got a breaker bar coming tomorrow on Prime and am running out of options. Any issues me getting the blow torch on these suckers??? Can't think of anything else to free them - I don't think the bush would be affected but my new wishbone has a new one anyways
