Pictures correspond to the written instructions that are numbered. DO NOT attempt to install your propeller without reading the written instructions FIRST! Please note that the new Apex series hub is not pictured here but the process for assembly is exactly the same.

1. Set the bottom half of the hub on the table with the cavities facing up.

2. Place the blades in the hub, labels up.

3. Place the top half of the hub on and put in the bolts.

4. Tighten the bolts evenly. The blades must still be able to turn in the hubs.

5. Turn and pull hard to seat the blades outward.

6. Mount and tighten the center bolts. Make sure the blades still turn.

7. It's easier if you work in the same position with every blade.

8. Put the pin in the little hole.

9. Combine the proper feelers to make .095".

10. Place the feelers in the gap between the pin and the window edge. See the written instructions for which side of the pin to place the feelers. Turn the blade firmly to squeeze the feelers.

11. Holding turning pressure, tighten the two outside bolts by going back and forth in 1/4 turns until the blade can no longer turn.

12. Tighten the inside bolts fairly snug. Criss-cross as you go so the bolts go down evenly.

13. Apply torque evenly to all bolts by going 1/4 turn on each bolt until you reach 175 inch pounds on every bolt.

14. Time to do a runup and see how you did.
