Do not loose the ball bearing centering spacer between the couplers.
You may have to re-use the snap ring that secures the old fan if the replacement does not have one. Make sure it is in the correct position on the shaft as to not interfere with the lift linkage.
Also a good time to replace the spirol pins if they appear worn as well as the rag joints if they are hard, brittle and distorted.
Be sure to use spirol pins and NOT regular roll pins
Be sure to support the driveshaft with something solid when driving out the spirol pins using a 1/4" pin punch with the centering tit on the end.
Good luck!

If I may add,
make sure the fan is put on correctly so it cools the hydro and the curved blades are facing correctly or it will not have the airfoil effect.
I have seen a few on wrong.
