Hoover WindTunnel Wheel Axle Repair

thingiverse

This is the second WindTunnel Hoover vacuum model I've seen with a recurring issue - the wheel axle passes through an unsupported plastic tube at its top. Over time and repeated stress from vacuuming on various surfaces, going up and down stairs, this plastic tube tends to crack, allowing the wheel to rub against the housing. This causes the vacuum to stop rolling. If you notice that pushing up on the wheel causes it to rub against the housing, this is likely your problem. The fix is straightforward: remove the c-clip holding the axle in place, pull off the wheel, and press the support piece into the opening as shown in the picture. To secure it in place, I used super-glue around the edges; ideally, it should fit tightly on its own. Reassemble everything, and you'll be back to normal operation. Since only one side was damaged, I added a support piece to both sides to prevent future issues. I've included an OpenSCAD file if you'd like to modify it for your specific needs or preferences. If you find ways to improve the design or if this solution saves your vacuum from further problems, please let me know!
