If your Hayward Navigator Pool Cleaner stops moving, one of the parts to look at is the Navigator's A-Frame. The A-Frame rides on top of the Main Turbine with a toggling motion that translates to the pods and four shoes. Over time, the four wheels on the A-Frame wear, begin to freeze up and need to be replaced. This guide shows you how to extract and replace the Navigator's A-Frame Assembly
TOOLS YOU WILL NEED -
1) Phillips screwdrivers small and medium.
2) Flat headed screwdriver.
3) Thin walled socket fitting
4) A work area where you can spread out. TIP: It is very important that you are careful when taking this apart. Have two or three containers to put the parts in to keep track of them.
SEPARATE MIDDLE BODY AND LOWER BODY - Pull the two sections apart. Once apart, they will look like this; the Middle Body on the left; and the Lower Body on the right. As you separate the two section, note how the wheels on the A-Frame in the Lower Body ride on the Main Turbine of the Middle Body.
REMOVE A-FRAME SECTIONS - One end of each A-Frame Section lays in the slot of the blue-green bearing. To remove the A-Frame, first lift the end of the A-Frame shaft up out of the slot, then pull the other end of the shaft out of the blue-green collar towards the center of the body. Repeat for the other A-Frame Section.
SCREW ON OLD PODS - Push each of the Pod onto the ends of the A-Frame shafts and secure them with the screws. Snug the screw in but don't over torque it or you will strip the treads. Also, check that the Pods are attached to the correct sides. There is a right Pod and a left Pod (as labeled on the wings). The "right side" is on the right when the screen end of the cleaner )back side) is next to you.
