Has your craftsman vacuum cleaner got a screaming bearing

[jabberwoki]

A feller on GJ responded to my query about fixing this problem.

[goodfellow]

The manufacturer (Shop VAC) probably used the bushing in the consumer grade units, and the bearing in the more expensive commercial units. It's a great fix -- thanks for posting Jabber.

I guess that in a pinch if a bearing size wasn't available, you could also machine down a sintered oil impregnated bushing to fit a motor shaft.

I picked up 2 bearings yesterday for $13

I have a couple "screamers"...gonna have to see if this will work for them.

[torqueman2002]

Thanks for the tip. I have a very old CM shop vac that just screams. I'll see if this will work on it.

Thanks for posting Jabber.

I've got a larger CMan shop vac with more than a few years on it so I may need one in the future.

So as you can see the bearing is not a snug fit . The outer race is a bit sloppy when you drop it in the bearing bracket so there's a possibility that the whole bearing will spin.
 There's too much gap for a thin glue like loctite i was thinking jb weld but that would be a bitch to replace in the future if necessary.
Constriction Sicka adhesive maybee? at least you could cut it out as it`s doesn't set up hard , but would it grip the metal surface of the bearing?
Maybe give the bearing surface some tooth before applying?

[torqueman2002]

Perhaps shim stock and/or one of these Loctite compounds for bearing retention.

I second torqueman2002 on the shim stock. That or aluminum or copper tape.

And it so happens I have some Al and Cu tape if you need. The Cu is about 0.003 and the Al about 0.004.

Thanks JAFE!   

I have some aluminum HVAC tape (not DUCT/DUCK tape). Not sure of the thickness, but I might give that a go, if I need to.

So touqueman we are the dark side eh?

Oh boy, have I done it now? What if Ryan follows me here? Think I'll get banned too?

[Uncle Buck]

Who is this Ryan you speak of and why would he care what anyone over here thinks about anything.

As for securing the bearing I would drill and thread a hole into the side of the metal cradle the bearing sets in then use a pointed set screw to secure the bearing from spinning. If necessary to center the bearing in the cradle repeat and use 2-3 set screws and holes to ensure the bearing is centered in its housing.

May be tricky as it`s a very thin pot metal piece.

I have to see if I can find a bearing locally.  Online purchase, the bearing is $2.16 and the postage is $10.35.  Stupid!

It seems to be a common size, even used in skateboards (but sold in packs of .

This is my Shop Vac, I also have an old Craftsman (I think) with the same issue.  It's a nice change to open something up and find what was shown on a youtube video!
