Rest the small Pozidrive screw to shutter the lubrication port. This screw will need to be removed to allow periodic lubrication of the spindle.
Check that the blades rotate smoothly on their axis to allow for proper feathering. The best method is to lift the propeller 45° above the horizontal, a position from which it must slowly lower without being stopped by the friction of the grease, to the step stop.
If the blade rotates under its own weight – it is in the right friction tolerance, and the assembly of the blade is now complete. Mount the other two blades in the same way. 11 If the blade rotates more difficultly, it does not react as it did during the factory test assembly, and it must be dismantled and the installation restarted. Push the pin in the OPPOSITE DIRECTION to the one of the installation. Clean the insertion groove of the O-ring and check for any residue or dirt that may be causing the jam. Repeat the assembly and testing procedure described above.
