I had to use a cordless torque wrench to loosen my front sprocket, it wouldn’t budge with a long breaker bar.
As my bike is the spoked wheel version, I parked it with the front wheel against a wall and sat on it with the rear brake applied while my chum used the torque wrench. We started on the lowest setting on the wrench but it didn’t budge until we got to 3rd setting, only using 2 second bursts of the wrench until it broke free.
I had read about the need for locktite, but had none available so used only the lower torque setting (115nm if I remember correctly) as was recommended by Greywolf on a thread somewhere on this forum, and a new lockwasher.
My thinking on the need for locktite was that it must be a bit of overkill, as surely when the bike is being ridden the drive shaft is only ever going to tighten up the sprocket nut? Can anyone on the forum with more knowledge advise on this?
