Loose pulley bearing

[calstar]

This is the intermediate pulley from my clausing 8530 mill, the top bearing(Farnir 201KDD) rides loose in the seat, I can wiggle it back and forth a little and it falls out if I turn the pulley over and tap it. Seems like I remember seeing some type of "paste" in a tube to sparingly apply into the seat to take up the play, anyone know what will work?

thanks, Brian

I've never dealt with a problem like this, but would it be possible to ID knurl the pulley to raise some material?

McMaster-Carr sells a Locktite product that will permanently repair a loose fitting bearing.

Check the bottom of the page for different compounds.

I agree.

Mcmaster carr runs expensive.
Shop around for the same locktite

The typical shade tree mechanic fix is to go around the ID with a center punch and a hammer. It will raise material to tighten up the bore.

Another option is to overbore the pulley and machine a sleeve that you can press in. Then set up the pulley and bore it for a slight press fit for the bearing. This was the standard fix in the shop I worked at years ago.

The bore and sleeve method would be the best practical choice, if you can do it. Loc-Tite will fill in small gaps, provided you have some means of keeping the bearing centered with the sheave while it sets. There are several types of epoxy based metal filled "putty" repair material that you simply knead together to mix. Some are a little stiff and it may be difficult to get an even, thin layer built up, but if you have a lathe, they are generally machinable and can be bored to a proper fit for the bearing.

I was at AutoZone this afternoon and saw some of the 2 part "putty" type, but I cannot remember the brand or exact name of it.

Download a bearing Catalogue. Identify the loose bearing INNER dimension or SHAFT size.

This is identified as lower case d in the first catalogue column.

Measure the outside bearing diameter and look in the second catalogue column which lists available bearings of a larger OUTER dimension identified as dimension
D upper case

From the catalogue, bearing 6301 ZZ is 5mm larger OUTSIDE diameter than your original bearing and the housing [hole in your pulley] is probably approaching that size so machining the pulley to accept the 6301 would seem to be the simplest solution.

I think this would be your best permanent fix. I just did the same thing on a rear main seal housing on an old Farmall Cub tractor.

The product is loctite 666, I have used it for years. It will take up to .020 clearance. Make sure everything is good and clean, smear on both surfaces and install bearing and shaft.
You leave it set for the time indicated or yo can warm it to 150 degrees to accelerate the set time.
