15HP 152BA Woodruff Key

Attached pic of the broken key. The part is no longer available and I have ordered some 1/8 x 3/4 ones.
Used a caliper to measure and seems pretty close.

There is a delay in getting these so I made one today. Correct me if i am wrong but this key is only used to align the shaft and flywheel.
The bore and shaft mating is the real key.

The manual I have indicates torque the nut to 45 +/- 5 ftlbs but this seems low. Is the 45 correct?

Thanks for any advice!

The tapers drive the flywheel if they fit properly and are clean and dry.---No 45 ft-lbs is not low for that motor.
