outside a/c unit, replacing fan and motor

We are replacing the fan and motor and capacitor on our old outside unit. They were replaced by brother 2 years ago and are not sure it was done properly then. Fan wallowed out and made terrible racket. We cannot go by the direction that the fan was mounted before. We are ok with the wiring et al. Question: Does it matter if the set screw are oriented up toward the motor or pointing down? Does the weight looking thing need to be put on the shaft nearest the motor or vice versa. This motor can be reversed...advice needed!

Welcome to the forums.

Normally the set screws go towards the motor. As far as rotation..... the air should blow straight up. If it doesn't.....it's turning the wrong direction.
