If your Hayward Navigator Pool Cleaner stops turning and gets hung up in a corner, you will want to check the Navigator's Gear Box Assembly inside the Navigator Cleaner. The Gear Box is one of the principle elements used in controlling the path of the Navigator. Occassionally you might get a small piece of hard debris in the Gear Box that clogs up the gears and keeps the Navigator from shifting left and right. This guide shows you how to access and replace the Hayward Navigator Pool Cleaner Gear Box.
TOOLS YOU WILL NEED -
1) Phillips screwdrivers- small and medium.
2) A work area where you can spread out. TIP: It is very important that you are careful when taking this apart. If you lay all the pieces out in a row as you remove them, it will be easier to put back together.
3) Three small Tupperware or paper bowls to put parts and small pieces in. Label them #1 – #3 with a magic marker.
INSPECT LOWER MIDDLE BODY - When you turn the Lower Middle Body over it should look like this. Sometimes the little red 3/4 circle show here (the Spinner) and the Main Turbine fall off their mountings and end up in the other section. Remember this when you are putting the two sections back together. Carefully lift out the red Spinner and the white washer that's behind it and put them in container #3.
TEST GEAR BOX ASSEMBLY - Blow into the little square hole on the angled end. The gears should make a high spinning sound. If not, or it sounds off, carefully remove the top and see if there is any debris inside of it. If you do open this, be careful that the gears don’t spill out. (I once found a small copper wire in one). If any of the gears are damaged, you will have to purchase a new Gear Box Assembly.
COMBINE MIDDLE BODY - Put the Middle Body back together by placing the Upper Middle Body on top of the Lower Middle Body. This can get a little tricky because the Rear Screen HAS TO slip into little grooves. Be sure to place the Upper Middle Body on top of the Lower Middle Body to keep the Spinner from falling off its post.
TEST GEARS - Turn the Cleaner upright and with the top of the cone gear protruding from the top of the vacuum, pull up on it and turn it. You should hear a nice slow spinning sound coming from the Navigator. If you hear any kind of crunchy sounds or the mechanism doesn’t sound right, then you did something wrong and will have to take it apart (that’s how I leaned!). However, before doing so, put it in your pool and see how it works.SHARE THIS ARTICLE:
