Topic tags/keywords: tablesaw repair question

I received my new arbor from Sears and the bearing nearest the blade mount is loose.

I tought it was supposed to be a press fit or am I wrong?

I would imagine that a loose bearing is as bad as a bad bearing. maybe your old bearing froze and wore out the shaft.

Ewww, do you really want to get into that? The latest saws are so nice and affordable. At the same time, a man that cherishes his grandfather’s tools understands the emotional attachment.

I can’t speak for your saw, but I just refurb’d an old Craftsman belt/disc sander with the same deal. I could push them onto the shaft with my hand. This was with the original bearings or the new ones, and I checked different unused spots along the axle to see if it had lost any diameter in the bearing area and it hadn’t, so the slip fit must have been like that since it was born.

Per recommendations, I ended up going with some loctite “retaining compound”. I used the 680, but I believe the 609 would have been the appropriate one for you and I.

Good luck on it!

PS- It would be funny if it’s from the same stock. This thing’s supposed to be for a 1/2” inside bore, but the shaft is a few thou too small.

How loose is loose? Is it just that you can slide it on? Or can you feel some play in it? Are the other bearings on the arbor the same size?

I believe the bearing became loose from being in the freezer overnight!
I had the arbor shaft/bearing in the freezer with the trunnion in the sun so everything would go together without any “banging” on the parts.
That worked like a charm, the trunion was almost too hot to handle, and the pieces went together with very little effort

I put the old bad arbor shafts in the freezer to see if the bearing would become loose and it did!

Everything is now back together I just need to install the belt pulleys, belt, and belt cover.

This was not a job for someone with RA and just too old to be a mechanic because steel and iron are not as hand friendly as wood!

Are you seeing/measuring any radial play or is all of the undesirable movement axial?

bigblockyeti, nope!
Got it all put back together late this afternoon and everything is working fine!
A beautiful sound of blade through wood and no bearing noise!

I have turned steel bearing to go along with my link belt and I had a little problem with the Woodruff key when trying to mount the bearing which was due to the slot in the new shaft was .006” shallow compared to the old shaft.
