It's exactly 19.5 inches across the centerline blade tip to blade tip. As far as the extra weight, I dont think it will be an issue, the belt tension dictates the force upon the bearing plus it's the water pump seal that goes bad, not usually the actual bearing.73challengerguy wrote:THANKS eddie....how wide is it again? tip to tip of the blades...thats the biggest problem is finding one thats not too wide and will rotate above my radiator...since i dont have a shroud...the ones i have found are so wide u couldnt even run a schoud, it would interfer......let me know....and do u think having the heavier,fan with the 7 blades, would be hard on the clutch bearing spinnin with the extrea weight of that fan?? anyone input here??
