Having just removed the original fan (TR4) for a water pump and timing chain replacement, I'm wondering just how important and/or effective the original over enginerred balance weight setup is. I suspect the position of the weights as someone else has be there befor me but I marked them befor removing, I'm tempted to just omit them when I go back together and see what happens. Would appreciate hearing from anyone with any experience with the original fan balance setup. Thanks: KSD
