Torque Settings - Engine Mount Bolts

How long is your lever? Plenty of wheel nuts are torqued to twice 80nm so I would not get nervous. You WILL need to lean on a stubby wrench!

 

Having just removed the front lower engine mount bolt to remove crash bar, I read the bolt should be tightened to 40Nm. I haven't yet a torque wrench for that setting, so I have had a guess and feel that should be good as the bolt is supporting a shear load. 80Nm seems massive to to me and could put undue strain on the frame lugs and the engine mount which is only a cast alloy.

 

As recommended in another thread about the Street Triple weld failures on the frame and recommendation to check bolt tightness, I want to check my Speed Triple's bolts

I have not used my torque wrench for many a month and know would not be accurate
Is it possible to rectify this myself?
Also, how should they be stored for long term - wound down completely or just enough so there is some tension?

 

A special tool called an acutorque is used to calibrate a torque wrench. False economy for us DIY people. It seems to me you need buy a new torque wrench, even the cheapest ones come with a calibrating certificate.
Storage is NOT under load and kept in its case.

 

Just found this in YouTube - answers my question

 

The old fashioned way is to make up something that you can tighten whilst held in a vice or frame and hang known weight a measured distance when the wrench is horizontal and calculate the moment. You can vary the distance and weight for different settings and adjust the wrench if necessary, or apply a correction if you don't want to mess with it.
