Polaris Pool Sweep, Fails To Move, Free Repair

The customer had a Polaris pool sweep that needed a nudge to start moving and begin to clean the pool.  Upon taking the sweep apart and doing a close examination of the parts, I found that one of the drive wheels was flawed.  The nut that attaches the wheel to the unit was found to be loose.  This allowed the wheel to cycle around in other than the correct angle to the drive shaft.  As a result, the metal drive shaft, over time, wore out the wheel gear teeth as seen in the image below.

 

The easy solution was that there were three wheels all the same in that they could be interchanged.  I needed the two drive wheels to be perfect.  The third wheel was not driven and it’s teeth did not matter.  I just switched out the back wheel with the flawed one and the unit worked.  This repair cost the customer nothing for parts, just labor.

CAUTION:  The lesson here is to make sure that each wheel shaft screw is tight.
