Hey everyone,
Long time lurker, first time thread starter. I have a second hand Ridgid BS14002 that I have been pretty happy with until the upper wheel shaft hinge decided to self destruct. I replaced it with the Grizzly version and that was an adventure unto itself. Once I got it running again, it seemed like it vibrated more than it used to. I had it out of commission for about 4 or 5 months, so it could be my imagination. When I first got it, I had to drill out a lot of each of the wheels in order to get them closed to balanced, then, finally, added some turns of copper wire around a couple of spokes in order to get the lower wheel balanced.
Now, after fixing the shaft hinge, I took the time to tune up the saw (adjust the thrust bearings, polishing the table, making sure the wheels are co-planer, and the saw just wasn’t very smooth. I opened the upper wheel cover and let it run for a little bit. I then noticed that the bearings were not in the dead center of the wheel, or at least did not look like it. I went out and bought a dial indicator to see if my eyes were lying to me, and it turns out that the upper wheel has about 0.055” of run-out. Is this acceptable? If not, are after market wheels available? I don’t want to shell out a ton of money, so, if it fits, I would probably get the wheel from Grizzly.
Thanks for taking a look at this

It seems like a lot of run out. Was that taken on the metal part of the wheel and not the rubber tire? If you indicated the tire, it may be worn in spots and deteriorated and stretched more in one place than another. If the metal part of the wheel is good and the tire is out, replace the tires,. But if the wheel is out check to see if the bearing is shot. That may give you a lot of vibration if the bearings have dried out and marked the race. I cannot see how the wheel it self would be out that much unless it was hit with something. I’d bet on the bearing or the tires. . With the blade off roll over the wheel to see if the bearings are rough. The bearings are a lot cheaper than a new wheel and they can be pressed out and new ones pressed in if you find that to be the problem.

I think Rigid has a life time guarantee on their tools. When you find out what is making the run out, it might be worth giving Rigid a call on the warranty.

Good luck!!............Jim

I would say that is not acceptable. This is going to sound nuts, but I actually remedied an issue similar to yours with duct tape. I was using a very old homemade bandsaw at the time and the tires had worn unevenly because the blade was left tensioned for years and years. This basically resulted in the wheels being ovals. To temporarily help fix the problem, I just layered duct tape on the skinnier parts of the tire to get it back closer to round. It didn’t eliminate the vibration, but I would say it fixed 80% of it. Just a quick fix if you need to do it. Obviously that isn’t a long term remedy, but I thought I would share it because I was surprised when it worked.

Thanks for the quick replies. To make sure that I was not measuring flat spots on the tires, I ran the point of the dial on the inside rim of the wheel (the point was aimed away from the center of the wheel). What makes me think that there is a manufacturing flaw is the fact that the recesses for the bearings are not centered in the thickened central part of the wheel. I have not measured it, but it is easy to see with the naked eye. I know that Ridgid has a lifetime warranty, but I think that they only honor it to the original owner, and only if you register the tool soon after buying. I might send them a note on their facebook page.

Ridgid has a lifetime “service agreement” on some of its tools, not a “lifetime warranty”. Two very different things. It is just a marketing trick; apparently one that works pretty well, based on the number of people who call it a warranty.

The bearing may or may not be centered in the thickest part of the hub and the inside surface of the outer rim may or may not have a lot of run-out. These are surfaces and geometries that don’t matter to the manufacturer. The only thing they check is the run-out of the outer surface of the rim when the wheel is rotated on it’s bearing. The off center hub and the off center outer rim’s inner surface only affect the balance of the wheel. Balance can be adjusted with lightening holes or weights, as you have already stated.

You can get the wheel here,

I would check the bearing and if it’s ok, then change the tires.

To find if the wheel truly is out of round you need to take the tire off, clean the wheel surface thoroughly where the tire runs and check the runout on that surface. That is the only surface that needs to be true. The rim of the wheel next to the tire does not need to be perfectly round and because of that may not have been machined fully. It costs to machine every surface and companies anymore will cut costs wherever they can.
The bearing need to be centered in the wheel in relation to the tire surface. If you can see that the bearing does not seem to be centered in the hub casting you may have a balance problem not so much a runout. While .055 is quite a bit of runout I am not sure the naked eye can see that much in an offcenter bearing.

You could take the wheel to a machine shop and get machined true

Even if the wheel is out by .055”, the rubber tire will compensate for it to an extent. Is the tire glued on or is it loose? A tire that is not glued, can shift and “bunch-up” in one place causing the wheel to appear out-of-round. If the tire is loose, remove it; clean it well and put back with (rubber cement). If the tires are rubber and have cracks in them, get rid of them and replace with new polyurethane tires.

I remeasured on the outer surface of the wheel and the run out was much out. It looks like more searching for the wobble is in my future. Next stop – link belt

Mike, I too am a secondhand ridgid bandsaw owner, although my saw has not had a broken part such as yours. I was having severe vibration issues like you are, was at the point of putting a quarter with the machine and pitching it to feel like i was losing something,until I found an older forum named ( Ridgid Band Saw BS1400 No Longer Avail. from Home Depot ? Did I get the last one ?) Tried to copy the link for you do not know if it worked. ( )
There were two posts from fellow L.J.ers David Grimes and Ferstler, i used info from them both which made my machine run smooth as silk.Namely the thicker base and new belt.
Hope there is some help in there or may cause you to find the solution good luck.

A fellow woodworker neighbor bought a new HF band saw, and had the same problem. The top wheel was out of round. Took it back after a couple of weeks and exchanged it for another one. We put it together and this one had a vibration also, but it was the tires.
