Well did it by hand and then checked with torque wrench out of curiosity, all exactly the same at 30 N/Mn, so happy with my ability to feel metal has not left me!

It’s an odd sort of self-confidence that refuses to use a torque wrench. We can all (!!!???) tighten by touch but why is it supposed to be a ‘failure’ to use the correct tool for the job? It’s the same mentality that leaves the mains current on when fitting a new socket in the wall!

‘Tighten by feel’ is a well-tried and tested method on engines with the tolerances of a static steam-engine!

Hi all this assumes our torque wrenches are accurate,,the one I bought some year's ago I had it checked for accuracy on a calibrated test rig in the company I worked for , it was only accurate in the middle range ,being low on the lower settings,and high on the top end settings,the other thing to think about,if you only use it now and again,you should first do a few torque retorque trial runs on a suitable bolt/ nut as again the results could be different ,because of infrequent use

Would that be referring to someone like Geoff Capes or Larry Grayson?

Don't try that with the camshaft clamps on a pre 2nd World War MG 1600cc engine. Torque wrench obligatory.

Yeah, working on old Reliant engines put me off torque wrenches - head bolts end up popping

Off topic now! 700 years ago, I worked for a Reliant main dealer. I remember a guy walking in and saying have you got an 850 engine. I went to the shelf and carried one over to the counter. Can’t imagine doing that with many engines....it’s was far lighter than my CB500T engine.

Torque wrenches are for people who really should not be tightening nuts. Oh dear Ive had this conversation many many times. Try working on outboard motors.

RR say don't over tight--if it leaks you can tighten some more.

Buy a packet of nuts and bolts from the hardware store and toque them to destruction in a vice. you will soon feel the bit where it stops tightening and goes soft and then breaks. If you get to that bit you are too late anyway.

[windmill john]

Rather than nuts and bolts, maybe tap a few holes in a block of aluminium. 3 to 4 different sizes, then pop bolts in and torque or tighten till they go, to get a feeling for buggering them in a real situation.

So how come RR issue a 10 page document listing a torque figure for virtually every fastener on the car?
