Topic tags/keywords: bandsaw

I have a 14” Jet JWBS-14X bandsaw (not the DXPRO) with a crooked upper wheel. Does anybody know if the wheels that you purchase from the online vendors include the bearing, or is that separate? Jet says that my saw is the same as the JWBS-14DX and the part number listed in my owner’s manual is 100186. I don’t seen the bearing listed separately and can’t get an answer from the sellers, so I was wondering if anybody here knew the answer. What I am looking at is this:

I just want to make certain this is all that I need before I order it. I was also wondering if the upper wheel from a JWBS-14CS would fit as they seem to be more current and cheaper.

Can’t be certain, but I doubt they include the bearings (or the internal retaining c-clips) – and I’ve never seen a vendor sell a wheel with them already installed without deliberately letting you know that they are. Use the c-clips from your original wheel and either re-use the old bearings if they are in good shape, or splurge the ~$10 for a set of new ones to be sure they are good.

Cheers,
Brad

Thanks MrUnix. How do I get the old bearing out? Is it press fit? Or just held in with the c-clips?

There should be two bearings… and you can just tap them out from the opposite side with a wood dowel or similar (against the inner race). Once you get one out, the other is easy.

Thanks again, I will go ahead and order the wheel. The seller said that it had been this way since new and had never been a problem, but I don’t know how he used it like this, or what could have happened to cause it.The blade has a fairly significant front-to-rear wobble. Of course he did have a 1/8” blade which probably minimized the effect of this movement. Actually I didn’t think it was that bad until I put on a 3/8” blade, then the wobble was quite obvious.

I received the new wheel today and it looks straight, but now I need a set of tires. What do people here recommend? It currently as orange tires that mostly look good, but I don’t expect I can reuse the one from the old wheel, correct? I would think that trying to remove it will ruin it. I see quite a range of prices when doing a search, anywhere from about $15 to over $50 (cheaper ones are orange urethane, more expensive ones are blue). Does anybody have a recommended type and source?

FWIW – I have successfully removed and reinstalled orange urethane tires before?

If the urethane tire on old wheel is not glued down with adhesive (can you slide something under it?), and not excessively worn; might be able to reuse it?
Put the old wheel in oven @ 200F for 10-15 minutes, and while wearing gloves, slide two flat blade screwdrivers under the tire, and ‘walk’ it off the old rim.
Check for any unusual thick spots or damage; if OK reuse it.
If you warm the tire in boiling water, can stretch the urethane enough to reverse the process.

Best Luck.

They should be pretty easy to get in and certainly are not a tight press fit – should be more of an interference fit which, if you get it just right, can be pushed in by hand. A suitable sized socket or pipe and a wooden mallet or similar works fine. Just make sure you tap on the outer race and keep the hub well supported while doing so. Might even get them seated by just tapping with a plastic/rubber faced hammer.

Cheers,
Brad

To make it easier to press the bearings, put the wheel in a 200 degree oven, and the bearings in a baggie in your freezer. The bearing recesses will expand, and the bearings will contract, giving you a tad more clearance.
