The Great White Pool Cleaner oscillator is key to having functioning cleaner, he creates an agitating action that promotes the movement and cleaning action of the cleaner.

Step by Step

Top

Step 1

Before disassembling your Sta Rite Great White Pool Cleaner be sure to disconnect the vacuum hose from the dedicated suction line of your pool. After hose is disconnected from the suction port then you may remove the Great White cleaner from the pool and remove the hose from the cleaner.

Step 2

With the Great White Pool Cleaner sitting upside down you should be seeing it from this vantage point. To access oscilator assembly you will need to remove these four screws to unseat the cleaner's drive and brush system.

Step 3

Using the two openings on either side of the lower body lift the lower portion of Great White Pool Cleaner out of the cleaner casing. Replacement Sta Rite Great White Cleaner Lower Body part #: 3290-11

Step 4

Turn the lower body over so you are looking at the gear assembly of the cleaner. Pop the oscilator chamber cover off the gear assembly, it is held in place by 2 latches on either side. Replacement Great White Pool Cleaner Oscillator Assembly Cap part #: 3290-06

Step 5

On the gear set not on oscillator's shaft there is a screw you must remove to extract the assembly. Once this screw is removed lift the gear assembly out of place. Replacement Sta Rite Great White Cleaner Gear Kit part #: 3290-08, 3 Leg Cam part #: 3290-07

Step 6

The gear set that was held in place by the screw can now be removed. Taking out this set will make it easier to extract the main gears of the Great White Pool Cleaner.

Step 7

While using the oscillator shaft as a grip, lift the assembly out of the lower body. At this point you can remove one of the rubber stoppers and slip off the gears and oscillatior itself.

Step 8

Before placing new oscillator onits shaft install the composite plastic half moon inserts in their grooves.

Step 9

The next few steps are mainly pictures to show you the order in which to place your new Great White Pool Cleaner gear set.

Step 10

First, place the oscillator onto the shaft.

Step 11

Then the pinwheel companion

Step 12

Place the gear spring onto the pinwheel support.

Step 13

The thick gear which chontrols the back and forth of the set goes on next.

Step 14

Then the skinnier gear.

Step 15

Finally the last gear with the support arms is installed. the support arms are what help stabilize the assembly while the Great White Pool Cleaner is in use.

Step 16

Place the new gear assembly into the lower bodyand reattach the cover.

Step 17

With the new Sta Rite Great White Pool Cleaner gear set body in place we can now secure the lower body with the 4 screws. Check for for any loose parts before resuming operation of your StaRite Great White Pool Cleaner.

Kent B - It sounds like the cleaner's suction is still too strong. I'd close the valve some more if you can. If that doesn't work, do through the replace procedure again step by step to see if you missed anything.

Prior to installing a new skirt on my GW9500, the unit worked like a charm, even with the old skirt in tatters and dragging behind the unit as it travelled the entire bottom and sides of pool without a hitch, Installed a new skirt which I found very intuitive, but the unit now doesn't move and gets hung up in certain spots. The oscillator seems to be working well, as well as the brush. Thought maybe the skimmer suction was too strong to allow it to move around, so closed the valve a notch and still no luck. Help!!!!

Anonymous (cleaner motion) - Check the gears shown in this guide to make sure the are not cracked or have teeth missing. Check the spring and other plastic parts for damage.

The cleaner tends to stay in the deep end
And not "roam" the pool. Any suggestions as to why .

FLIP - If the gears move when you move the oscillator, it sounds like the mechanism is working. Check that you have enough water flow in the suction tube to drive the cleaner.

I'VE REPLACED THE GEARS INCLUDING THE GEAR WITH ARMS. AND THE CLEANER IS NOT TURNING? IN MY HANDS WHEN I MANUALLY TURN THE GEARS (OSCILLATOR)IT TURNS AND ENGAGES THE BRUSH. BUT NOT IN THE POOL?

Great White - There is no fine tuning that I know of. Take the cover off and with the oscillator in place, work it back and forth to see if any of the gears are binding. Check your reassembly. Here's a link to its User's Guide for another explanation of disassembly and reassembly (pgs 16 &17). If you see no solution, call their customer service at 800-831-7133.

I used a great while from 2001 to 2012. Bought a new one now in use. After about three years it started to go "straight", (Oscillator not working). I replaced the three identical gears, the GW functioned fine for about 3 months, then started going straight again. I just put in a new set of 3 similar gears(the repair kit) and the the unit shortly there after started going straight again. This means the oscillator is not working? Is there s "fine tuning" tip, or those other gears that need replacing or the placement of the gear with the "arm" that moves the brush in and out?

enlarge picture - We are working at increasing the size of these smaller pictures, but until that happens, you can increase them somewhat by increasing the magnification of your computer display. This option varies with your computer but it is generally controlled by an icon in the upper right corner of your computer screen.

I wish I could have blown up the pictures a little. They are pretty small

One thing not mentioned: You need to remove the inlet fitting from the top of the unit first; it holds the lower assembly in place as well. It is a twist lock, simply grab the two tabs on the side and rotate it 90 degrees to unlock it and remove it.
