Band saw problem.

My Grizzly 14" band saw is making a loud high pitched sound when I am sawing anything, no matter how large or small. I have on the saw now a brand new Timber Wolf blade. I have tried and tried to find where it's coming from but it's hard to tell without help. With the saw just running it runs very smooth. I hope someone has got an idea that will help.

Thanks.

Most likely a guide bearing.



I've had this happen and I put a little oil in the bearing and the noise when away. I eventually ended up replacing the bearings.

Remove the blade first

You need to isolate the source of the noise. If it still squeals when the blade is off, it's in the lower drive train, a wheel bearing possibly, or something rubbing on the wheel a chip of wood possibly.


With the blade back on, the same goes for the upper wheel, a bearing or something rubbing, like the blade guard against the tire. A blade guide may be rubbing on the blade because it's snugged up too tight.
If the blade gudes are ball bearings, one of the may be dried up.



It could also be a motor bearing if you can remove the drive belt.


That should give you all the possibilities.

The answer to your question will only be as detailed and specific as the question is detailed and specific. Good questions also include a sketch or a photo that illustrates your issue. (:< D)

Doctor I haven't thought of oil. I really thought the bearings were sealed. I will give it a try.

Thanks.

It only makes the noise when cutting wood. With the saw running and not cutting wood the blade doesn't touch the bearings so the bearings might need some oil.

When you cut wood you push against the thrust bearings that support the back of the blade. If those are ball bearings, that probably the source of the noise. Typically they are sealed and there's not a way to lubricate them. Oil is not the answer except short term. There will be a stamped number on the shields for replacement ordering.

Like these for a Jet:

Grizzly uses the side of a ball bearing for the rear guide. see the the right hand side of the pix...


it's adjustable. if it is set so the blade contacts the bearing at just the right spacing, friction can make the blade sing like a violin string. that will depend on thickness of blade, blade speed, etc.


try moving the rear guide a bit left/right and see if that helps.

I put some Kroil Penetrating oil and the noise quit. It looks like I need to replace the bearings. If you haven't used Kroil Penetrating oil you should try it. I think it's the best.
