Topic tags/keywords: bandsaw band saw parts delta

I purchased a Jet JWBS-14CS off of craigslist and I’ve been trying to tune it up (which is hard because I’m new to band saws but here we are). I noticed that the lower wheel seemed to have some resistance when trying to spin, so I removed the belt and it still wouldn’t spin freely. I took out the the hex bolt and found a plastic washer with some ball bearings in it.

After removing that piece the wheel now spins drastically better. It’s not as smooth as the top wheel and you can hear a sound as it spins, but it’s much better. I checked the parts list and identified it as Part 52, the ball bearing, but the few places I’ve found online that look sell it show a picture that looks a lot different. Any ideas where I could find one that will work? Also, any ideas about the sound it’s making as it spins now? Is that normal or is there something I can do to fix that as well? Thanks!

I think you have been punked by a PO… the parts listing shows it the same as the Delta (which the Jet is a clone of), with just a standard washer. Sounds like you just need to replace your bearings (do the top ones also while you are at it) and get it back into OEM configuration (with a washer).

Cheers,
Brad

PS: Part #52 is a standard off the shelf 6204 bearing, and I bet yours are still in the machine – it is certainly not that thing you took off.

MrUnix I’m having trouble identifying the actual part. Do you know the bearing specs?

Sorry, just saw your edit. Thanks. Would you suppose the top bearings are the same as the bottom? They are listed as two different numbers.

Different numbers should be your clue :)

No, they are not the same… almost all of the cast iron 14” Delta clones I am aware of use 6202’s in the upper wheel, and 6204’s on the lower one. Although, the general advice is pull the ones you have now to make sure – there is no telling what a PO may have done in the past as you have already seen.

Cheers,
Brad

I’ve gotten super confused so I went back out the shop to look things over. The weird little “bearing” I took a picture of was located in the place of part 9. I believe a previous owner must have used it as a washer. The bearing itself is lodged in the frame as you said and seems to rotate fine. I got confused because I assumed the washer I had was correct which would have meant it had to be some type of bearing. The bearing is much larger though. And I verified the bearings are the correct ones.

The washer is WF083030. It’ll cost me $10 to have it shipped here. Is there a way to figure out the dimensions so I could just go and pick one up for Lowe’s? Would there be any harm in that?

OMG – you would have to be nuts to buy a washer for $10! There is absolutely nothing special about it at all, and you should be able to get one at your local hardware store or BORG for a few cents. Poking around for a cross reference, it looks like it’s just a plain M8 flat washer.

Brad

That makes perfect sense. One last question: were you able to watch the video I linked to in my first post, concerning the clicking sound? Should I attempt to remove the belt pulley to see if there’s an problem on the other side, or should things be fine the way they are? Should I try to get all that rust removed? I’m just trying to get this thing in as good of shape as possible before I start using it.

Edit Upon further inspection, the parts diagram shows that the washer doesn’t go between the wheel and the ball bearing, but rather the wheel and the bolt. Does that sound right?

That is correct, and it’s what holds the wheel onto the shaft. And I just looked at that video and realized the brain fart description I gave in my previous post (which I have removed). I only have Delta’s here at the moment, which are a bit different (use a nut instead of bolt) and was going on (bad) memory. Actually, it also looks like that is not the correct wheel as there should be a shoulder machined into the hub just below the hub face for the washer to sit on – and I don’t see one in your video. That may be the reason for that improvised washer the PO used. Can you take some better pictures of the wheel hub? Hopefully someone with the same machine can compare to what they have to verify.

Cheers,
Brad

I believe there is a hub on the wheel like you’re talking about. I took a few pictures earlier so I’ll just share that whole album. If you need more I can try and get some in the morning (don’t want to risk waking up the baby).

LOL – Ok, after looking at that video again, I believe you have the wheel on backwards :)
(The Sharpie “X” written on it should be on the back side)

Also, I’m not sure if you just had it removed for the picture or if it was like this, but the keyways should align and you should have a straight key (5mm X 20mm – another hardware store item for a few cents) between them to keep the wheel from spinning on the shaft:

I had indeed removed the keyways. What you’re saying makes perfect sense, as the bottom wheel was not coplanar with the top. I believe flipping it over will get it at least closer to being in line. However, I am curious what the purpose of this metal ring is for? It made sense to me to be on the side of the bearing if they were supposed to rub.

Do you think it’d be worth removing the belt pulley and inspected the shaft on the other side? I loosened the set screw last night but I couldn’t manage to move the pulley. Not sure if that’s by design so I’m hesitant to start using much force, especially if it’s not worth it. I do know, however, that the noise I showed in the video continues when I spin the shaft after I’ve taken the wheel off, so I know it isn’t due to how the wheel was set up.

Have your say...
