I was wonder if anyone else has had this issue or if it was just me. The sheave on the bottom of the mast for the main halyard hasn't been spinning correctly when raising or lowering my main. I replaced it 3 or 4 months ago because the halyard had cut into it and created a flat spot so it wouldn't spin. I just noticed lest time I was out that if was doing it again. The sheave spins freely when it's not under any load but something keeps it from spinning long enough to make a flat spot and it gets bad real quick from there.
Is this something that needs to be replaced frequently or is there something wrong that I'm doing? I have a feeling that it's the later...
