It is best to remove the propeller to
replace a damaged blade. Once removed:
1: Loosen the locking screw on the thrust ring (part H on the diagram) and back off
the thrust ring until you gain access to the flat-head socket screw (F) in the locking plate (part E )
2; Back that screw off about 3/8 of an inch. Do not completely remove the screw as
you may lose the locking plate.
3: Slide the locking plate away from the spindle (part d), thereby unlocking the blade.
4: Remove the blade.
5: Transfer any hardware missing from the replacement blade to the new blade and place
the new blade over the spindle.
6: Slide the locking plate toward the spindle until it engages the groove on the spindle.
Tighten the locking plate screw. Notice that the screw turns quite hard. This is to prevent the screw from backing off during
operation of the prop.
