I have found a nice replacement crank arm (I o it needed the left hand arm) it should arrive in the next few days. I will keep you updated as to how the installation goes.
Oh and I don't have a torque tench so I'll just do it up as tight as I can and then keep checking it as I ride, unless any one has any tricks to figure out how tight it should be?
Many thanks.
Not enough is very bad. Too much is very bad.
It's easy to get enough torque without a torque wrench. Just use a cheater bar. But since you can't tell the difference between enough and too much, you risk damaging the arm.
Buy or borrow a torque wrench.
