14/1 is a CV joint element in the exploded sub-diagram; it is not the output flange shown in the your posted image. Why are you removing the output flange? To replace the shaft seal? It is not necessary to remove this output flange to drop the engine/transmission. To remove the output flange put a couple of inexpensive 8.8 strength class M10 screws in two of the tapped holes in the perimeter and place a bar through them. Use this set up to react the torque required to loosen the center bolt These center bolts have standard right hand threads; they loosen in the usual counterclockwise direction when looking straight at them. Once the screw is removed. The output flange then pulls out, followed by some transmission gear oil if you haven't drained it. When reinstalling the screw (yes it can be reused) tighten to 20 ft-lbs if it came with a washer under it - a 1973 915 should have this washer. Use the two M10 screws in the flange to react this re-tightening torque.
