Delta Bandsaw Repair

Hey All,

I have a second-hand Delta Bandsaw (28-206). I need a hand smoothing it out. When it runs, there is a shake to it. I've tried to narrow it down by spinning the wheels without the blade to turning the wheels while under tension. The rub/click/noise occurs only when the blade is under tension. Seems to come from the top wheel, and occurs in several times during the wheel rotation. I am guessing a bad bearing. However I would expect to feel it when the blade is out of tension.

Any help, advice, or approach would be appreciated.

Thanks and have a great weekend.

Greg

A ticking sound .....

That kind of sound is typically from a weld that's not smoothed down on the sides or in the rear. It may also be a crack forming near the weld. It may be as you say, a dry bearing. Those have numeral codes like 6200 followed by letters that indicate the type of shielding to keep out the dust.

Several choices on this page:

I think I'll pull it apart to see if there are any rough/cracked welds. Will the part number be on the bearing? I have a Delta part number from the manual (920-04-010-7272), but not a lot of those available. Can I just pull the old, measure it up, and buy a couple stock bearings?

Thanks again,

Greg

Delta doesn't make bearings ...

You don't need their brand. The numbers I referred to are generic and are the same across all makers brands.

For instance:
https://pgnbearings.com/products/620...hoCmrsQAvD_BwE


OR these:
https://www.amazon.com/s?k=6200+series+bearings


The numbers to search for are stamped on the shields and when you take them out, you'll see.

Can you give me a little insight on how to remove the top wheel? I removed the nut and washer, and a set screw in the top wheel, but the wheel does no seem to budge. Tried a wheel puller, but do not want to torque too much and bend/damage the wheel.

Once again, any insight would be appreciated.

Get the wheel off. Bit of WD-40, hammer tap, and wheel puller. Now, what is the easiest way to get the bearings out?

Thanks,

Greg

one bearing or two?

If there's one bearing it's pressed into a lip. Find a socket that's smaller than the lip opening and tap it out with a dead blow mallet. You can press the bearing out using the socket and yuor drill press if you can apply enough force ... I donno?


If the bearing is bad and makes ticking noises, don't worry about preserving it. Just hammer on it using the socket between the hammer and the bearing race. Take a close up photo of the numbers and post it here.

Two bearings (one on each side), so I am not sure I can push them both through. I tried tapping them with a wood dowel, but no movement. Thinking I may need an inner bearing puller. I really hate to start banging away at it and damage the hub. The inner bearing does have a bit of a tick to it, so I will be replacing them.

Creative use of sockets and a bolt .....

You need a socket larger than the opening and a bolt long enough to run through both bears, a washer and a nut. When you tighten the nut it will force the bearing into the larger socket. A small length of 2" or 3" PVC with a plate with a hole for the bolt or large washer would work. I'm thinkin a 1/2" bolt would fit through a 1/2" socket..... ?
MacGiver this until you get it done!

Got em out. Glad I took the set screw out. Looks like it was holding a bushing inside the wheel. Attached are a couple pictures. I believe the bearings say 6202RS. Thanks a whole lot for walking me through this. Putting the new bearings in, once I have them should be a whole lot easier.

Hey Guys,

Replaced the upper wheel bearings, and did a couple other vibration isolation improvements, and the saw runs lie a dream. Thanks a lot for all the help!

This will happen if you include a link that was "third hand" or a very large image. it's happened to me several times. I don't have a cure for you, except just leave out the link.
