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

[Der Bugmeister]

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.

[jabberwoki]

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.

[torqueman2002]

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.

[jabberwoki]

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

[Der Bugmeister]

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!

Oh boy, just when I thought fixing my old 16 gal. Craftsman ( cir. 1980) shop vac was going to be quick and just like shown on YouTube! 

Well, I did find an illustrated parts list on ereplacementparts so there is that. Parts are NA, no problem 'cause I was able to find the bearings (NTN 608 LB) several places.

I was able to get it apart with a bit of effort - mostly fighting rusty fasteners holding the lid and inner lid assemblies together. They had to be separated to remove the motor frame assembly, to get the armature assembly out, to get the lower bearing off the armature shaft, ...

I'll have the bearings on Tuesday 12/7/22. $18.50 shipped from Grainger, including tax. And yes, it cost more to ship than the 2 bearings cost.

More than once I thought to just stop and buy another shop vac for use in the basement, but other than the terrible noise, it did a fine job.

Here are some pics. to show what this model 113.178200 looks like.

1st shows the upper bearing with cooling fan on the armature.
2nd shows the fan that creates the vacuum attached to the lower armature. The inner lid has been removed.
3rd shows the fan removed from the armature shaft, revealing a plastic 'spacer'. The 4 motor frame assembly screws are now accessible.
4th shows the lower bearing and 'rubber' cushion that mounts with the bearing when assembled.

Did mine today now runs like a champ.

Yeah, sounds like the same process I had to go through to get at mine.  The Vac is probably over 20 years old by now, and no idea how old the Craftsman one is.  Metal canister at any rate.
It seems like a common bearing (22 mm OD, 8 mm ID, 7 or 8 mm thick) so there are a few places for me to check around here before lining the post office's pockets.

Both of mine almost got binned, but they both still work despite the caterwaulling.  I have a new ShopVac which is nice and clean and ideal for using in the house.  Fixing the other two means I can keep one in the shop and another in the garage so I don't have to chase all over hells half acre trying to remember where I left it last!

Great!

[torqueman2002]

Yup, the bearings on the way are:
OD  22mm
ID     8mm
W     7mm

Once I figured out I was looking at the numbers upside-down, it was easy to find cross-references on NTNs site.

I stopped by my local auto jobber today and picked one up.  "608 2RS".  Cost me a whopping $4.78 CDN, so like two bits USD :-D

So the question now is where to get a OEM quality air filter. The new ones at Lowe's are to short and the ones on amazon look like cheap china junk.

I'm having the same challenge for model 118.178200 - NA on Sears parts and ereplacementparts websites.

I do have the original, very dirty filter that I plan to clean, measure and search for something I can adapt, to make work.

I'll post a follow up.

[Uncle Buck]

Check with a vacuum cleaner repair shop.

[jabberwoki]

That's a good simple idea.

[ron350]

 The foam filter's that Lowes and Home Depot sell are 6 inches tall how tall is the Craftsman filter?

[jabberwoki]

Dis big

[ron350]

Wow that filter looks like it fits a large shop vac.

The shop vac I have looks like the one in the video but it uses the 6-inch tall foam filter. About every 10 years the foam filter falls apart and needs replacing.

[torqueman2002]

I have a 'newer' CM shop vacuum, model 113.177611.

It takes a 9-17186 'Red Stripe' filter.

Bottom OD, not including the filter material ~=6.50"
Height ~= 7.75"

Non-OEM replacements on Amazon from $15 and up.

=======================

BTW, I found a universal replacement for my old CM shop vac, model 113.178200 at Lowes.
 
Bottom OD ~=6.75"
Height ~= 9.25"

That is very close to the original filter. I should be able to try it out this weekend.

As i mentioned the amazon/chinese filters look super flimsy, i may be wrong . let me know if you guys have used them.

I thought the filter looked like one I bought for my 'newer' CM shop vac.

I checked the original package - 'shop-vac' 90585, Type R.

It is almost 6" tall, so it doesn't cover all of the CM filter.

Mine takes a red stripe too. Fortunately my local vac shop repair guy that works out of a local hdw store a few blocks away stocks that one.
