I don't know about any of you, but this wheel has broken before.
I ordered a new one, which are only about $13.00. But it takes me a few days to get a new one, which are a few days I wouldn't have a vacuum working. Also, I when I have the new one, I will now still have a spare.
I used this product to FUSE, or "weld" the plastic together. It is called "Tenax 7R". Available in hobby stores. (I have NO affiliation with this company. Just good stuff I've used)
Just remove one Phillips head screw to remove the cover, and and two more to remove the wheel.
Then use a Q-tip to lightly coat all the mating surfaces. Don't go crazy, as it will just take a while to "dry". You just want both sides tacky to use HEAVY hand pressure to fuse them back together.
While holding it TIGHTLY together, I rub the joint with the compound to make it look finished, and a complete-through-plastic-weld.
This Tenax 7r will work on any part of that white plastic.
WAIT 8 HOURS...
Ready to re-install!
