Default Milwaukee 2629-20 blade comes off

I have a milwaukee 2629-20 bandsaw that the blade keeps popping off. I tried a new blade, but it still does it. Any ideas?

How old is it?

Could a wheel bearing be worn?

Someone suggested worn bushings? Is that possible?

I'd think you can feel if there is much play on the bearings themselves and it would take quite a bit of wear on the bearings before the blade would slip off. The tires are more likely to be the wear part, it's just friction that makes the blade go around. They might not even be worn, just glazed.

This could turn out badly but I wonder what would happen if you applied a little automotive belt dressing to the tires, might buy you a little time.

A proper crown on at least one pulley is essential to a stable self- centering operation.
This can be from a crown on the pulley itself or a thick center on the belt, or a combination.

The tires are less than $3 a piece so after 5 years in service $6 in repair parts is nothing to invest.

Most common is worn tire. the other item is the roller guide that is second most common wear part.

you may have to get one of the construction square to check the wheels to make sure they are line up properly too sometime but not always but the frame can get little bent too if dropped often.

so just check it out after ya pop in the new tires then it should be good to go.

I had a bearing go bad on my Milkw. electric bandsaw very prematurely a while back, that was why I mentioned that first . It was easy to see with just a quick look.

Only time I've had to swap one out.

It is normally just the tires.

Are you putting the blade correctly between the 2 roller bearings? There are 4 of them, 2 on each side of the cutout opening.

THose bearings will fail after time, usually the saw starts making really sloppy cuts when that happens.

Yep, doing that. Everything seems tight. It bugs me...probably a simple thing, but I'm not finding it.

If the tires didn't fix it then worn bearings is the next likely cause.

It didn't take a really hard fall at some point did it?
