Patching and gluing doors.
Took my shop vac apart again. After I replaced the switch earlier this year, it started making bad noises. Motor shaft bushing wear is common on these, from what I found on YouTube.
The yoke that holds the bushing is an assembly, not meant to be disassembled. There is a bit of oil soaked felt hiding under a tension ring, and the whole mess is staked in place. YouTube shows several versions of hacking this apart.
I chose the carbide burr in a die grinder. Remove the staked portion of the yoke, and the old bits fall out.
Sealed bearings, a cheap 10 pack from Amazon. They fit, but with a bit of play on both ID and OD. Some YouTube repairs ignore the sloppy fit and it seems to work. One guy used “bearing stick” to take up the slop, seemed like a good idea, so I did that.
Reassembled and left the bearing stick to cure. Will test tomorrow to see how the bearing works.
Cleaning up, pulled the die grinder off the air hose, and got a whoosh of air from the chuck.
Tear down of Milton “V” air chuck. Put hex end in vice, unscrew the top with channel locks. Don’t let the balls escape.
A trip to the hardware store netted me two new O rings. $2.
The larger ring goes in the body, seals the male plug when inserted. The smaller ring goes in the threaded end, seals the chuck when there isn’t a tool connected. The smaller one is the one that failed.
Reassembled and reinstalled on the hose.
