If your Pentair Kreepy Krauly Sand Shark slows down and you have noticeable wear on the scrubbing teeth of your Pentair Kreepy Krauly Sand Shark Pad, you may have to replace the pad with a new one. This guide shows you how to replace the Pentair Kreepy Krauly Sand Shark Pad. Unfortunately the pad only comes mounted on the Pentair Kreepy Krauly Sand Shark Chassis, so you will also have to replace the chassis to replace the pad.

Step by Step

Top

Step 1

ORDER PARTS - The first step is to order the parts you will need. The only part required is the Pentair Kreepy Krauly Sand Shark CHASSIS AND PAD.

Step 2

PULL OFF VACUUM PAD - Carefully peel off the rubber Vacuum Pad over the lip of the Outer Housing. You might need to start with a screwdriver.

Step 3

LIFT OUTER HOUSING - After the Vacuum Pad is completely off, you should be able to lift the Outer Housing straight up off the Chassis and Pad. The balance of this guide involves stripping the Pentair Kreepy Krauly Sand Shark control assemblies off of the Chassis to get down to the basic Chassis (and Pad).

Step 4

REMOVE SEAL FLAPS - Gently pull the Seal Flaps out of their grooves.

Step 5

RELEASE DRIVE SHAFT - There are two Sprocket Clips. Squeeze and pull out the Drive Shaft Sprocket Clip and shaft (as shown) to release the Drive Shaft Assembly.

Step 6

RELEASE CENTER SPROCKET - Squeeze and pull out the other Sprocket Clip to release the Center Sprocket.

Step 7

PULL OUT OSCILLATOR - Turn the chassis over and pull the Oscillator straight out from the bottom of the Outer Housing. The Oscillator is clamped onto an inner Oscillator Sleeve so you may have to pry it off gently with a screwdriver. The 4 Sliding Seals are loosely attached to this Oscillator and may fall out when it is removed. Keep track of them and see how they are positioned before they fall off.

Step 8

PULL OFF SWIVEL HOUSING - The Swivel Housing is attached to the top of the Chassis. Gently pry the four corners out of their slots with a narrow blade like a chisel.

Step 9

LlFT COG WHEEL - Once the Swivel Housing is off, you will be able to lift out the small Cog Wheel that was directly under the Swivel Housing.

Step 10

REMOVE STAINLESS STEEL SHAFT - Remove the Shaft Plug by the Large Steering Dive Wheel. Pull out the Stainless Steel Shaft connected to the Shaft Plug. Pull out the other Shaft Plug on the other side of the Chassis.

Step 11

REMOVE STEERING DRIVE - Pull the Large Steering Drive Assembly straight up away from the Chassis. You might have to push it away from the Chassis a little as you pull it up to have it clear part of the Chassis.

Step 12

REMOVE OSCILLATOR SLEEVE - Remove the Oscillator Sleeve from the Chassis. This is a tight fit so you have to play with it a little.

Step 13

REMOVE CLUTCH ASSEMBLY - When the Oscillator Sleeve is out, you will be able to lift out the Clutch Assembly. Once this assembly is removed, you will be down to the basic Chassis and Pad.

Step 14

REPLACE OLD CHASSIS AND PAD - Replace the old Chassis and Pad with the new Chassis and Pad. Check to make sure all the assembly parts are off of the old Chassis.

Step 15

REINSTALL OSCILLATOR SLEEVE - Replace the Oscillator Sleeve into Large Steering gear side of the Chassis. Again this is a tight angle so you may have to force it a little.

Step 16

REINSTALL CLUTCH ASSEMBLY - Before the Oscillator Sleeve pokes through to the other side of the Chassis, drop in the Clutch Assembly so that attaches to the end of the Oscillator Sleeve.

Step 17

POSITION LARGE STEERING DRIVE - In preparation for installing the Large Steering Drive, position it so that the notch in the center disk is down. This notch will engage with a vertical ridge on the side of the Chassis.

Step 18

REINSTALL LARGE STEERING DRIVE - Drop the Large Steering Drive over the end of the Oscillator Sleeve. Line up the notch with the vertical ridge just under the Oscillator Sleeve. Angle the Large Steering Drive away for the Chassis initially to clear the end of the Oscillator Sleeve.

Step 19

REINSTALL STAINLESS STEEL SHAFT - Reinsert the Stainless Steel Shaft into the Oscillator Sleeve.

Step 20

REPLACE 2 SHAFT PLUGS - Replace the two shaft plugs on either end of the Stainless Steel Shaft.

Step 21

REPLACE COG WHEEL - Drop the small white Cog Wheel in its place on top of the Chassis.

Step 22

REATTACH SWIVEL HOUSING - With the Swivel inserted in the Swivel Housing, place the Swivel Housing on top of the Chassis. The four tabs on the bottom of the Housing should be over the four slots in the Chassis and the Clutch Clip should be over the Clutch Assembly Wheel. Press down on the Swivel Housing until it clicks. Check that all 4 tabs are engaged.

Step 23

POSITION OSCILLATOR SLEEVE -Turn the Chassis over on its back. The Oscillator will snap onto the Oscillator Sleeve installed above. Position the oscillator sleeve so that its smooth side is up by rotating the Large Drive Wheel.

Step 24

REINSTALL SLIDING SEALS - Place the 4 Sliding Seals into the Oscillator. The little notches on each Sliding Seal should be place down when slid into the Oscillator.

Step 25

REINSERT OSCILLATOR - Push the groove on the bottom of the Oscillator onto the Oscillator Sleeve. The flush side of the groove should be on the Chassis side across from the Large Drive Wheel.

Step 26

REINSTALL DRIVE SHAFT ASSEMBLY - Replace the Drive Shaft Assembly and secure it with the Sprocket Clip with the longer shaft.

Step 27

REINSTALL CENTER SPROCKET - Replace the Center Sprocket above the other end of the Drive Shaft and secure it with the other Sprocket Clip (short shaft).

Step 28

REPLACE SEAL FLAPS - Press the Seal Flaps into their respective grooves.

Step 29

PLACE OUTER HOUSING ON VACUUM PAD - Position the Outer Housing over the Chassis and on the top of the Vacuum Pad.

Step 30

ATTACH PAD ONTO OUTER HOUSING - Work the edge of the Vacuum Pad over the lip of the Outer Housing.

Step 31

CLEANER IS READY - Check that you do not have any extra pieces that weren't installed. If not, your Cleaner is ready to go.

You guys are phenomenal!!!! Only thing I would add is I had to remove screws in step 10 and replace them in step 20. INYO Pools is awesome!

Such great detail in the photos. Wonderful description. This gave me the confidence to check the damage after a Texas hail storm. The only replacement that I learned I needed was the flaps! It was a little tricky gently prying the many white button plugs style chassis away (w/ a flat head screw driver) without damaging it. Great success from your detailed descriptions. Keep up the great work!
