The blade set

for my 16” BMY is out of whack. At least one, if not more, of the fingers appear pushed back so the blades hang back. One was severely out of clock and I was able to bring it more in line but not sure how to pull things forward.

I would put the blade on the fan then grasp the blade you want to bend fore or aft with your broad palm and pull or push.  Just be sure to put even pressure over as much of the blade as you are able to.   The brass on the blade is much softer than the shaft on the motor so no risk of bending the motor shaft.  After you bend fore and aft to line up the wings check the "clock" again and adjust if needed, etc.

Thanks Steve. What is the likelihood that the finger to the blade most out of clock, pitch, etc is bent. It kind of looks a bit like it’s twisted slightly on the hub. Maybe just adjusting the wing is all that can be done?  Thanks again.

I don't think the hub fingers are that hard to bend but I may not have adjusted a GE blade hub finger.   Anything is possible on bent blades from out of clock to fingers bent fore or back or twisted.  It can be time consuming to get all lined up correctly.

And let's not forget that GE purposely whacked some blades out of clock to balance them rather than weighing the wings and removing material. 

So it's possible to adjust clock to perfect and make it unbalanced. But generally that wasn't the case.

Thanks Lane.  I’d read about that. A little GE fine-tuning!
