Not me, but I’m jointly culpable.
Ive been helping my neighbour rebuild his TVR Griffith. It’s been a long job, but end is in sight. Body back on the chassis, engine running. Just needed to do up the stub axle bolts at the rear.
c.300Nm. Mate whips out the monster Sealey torque wrench. Asks me to do up the nuts (I’m younger, fitter *ahem* than he). I start at the Offside hub, RH thread, properly lean on the torque wrench 300Nm isnt fannying about. Get a click. All good.
Go and do the NS axle. Flick the reversible switch on the torque wrench, do up the LH threaded nut CCW, lean on it. No click yet, lean again, nut keeps on tightening, keeps on rotating, until it doesnt get tighter, it gets looser. That’d be stripped threads. We assumed that the old stub axle threads were ropey. He tracks down a replacement and without me around, does it all again. Stripped threads. We then test the wrench in the vice and sure enough, the torque measurement only works CW, not CCW.
So would you assume that a reversible ratchet torque wrench could measure torque in both directions or just CW? Obviously not many people come across LH threads, but at home bike assemblers like most of us will have in the context of pedals and BB cups at least.
We feel like a right pair of chumps, and poor matey is down a fair few quid buying up all the spare NS TVR stub axles in the country.
