Topic tags/keywords: question bandsaw

Hey LJ’s,

I’m back with another head scratcher for me
.

Bought a 17 inch Grizzly Bandsaw 2 HP with steel wheels instead of aluminum two years ago. I replaced my GO555 as I needed more HP for ripping logs and making veneers.

Needing to cleanup my spaulting/rotting logs and decided to put the 3/4 blade on the machine.

After adjusting all the guides and cleaning the wheels I put the big blade on. Significant rubbing metal noise. Checked everywhere to localize the sound. Removed the blade and ran the motor without…no noise.

Put a 1/2 inch blade on and the noise was less???

Varied blade tension and less tension…less noise.

I’m guessing my problem is in the pulley or bearings?

An inquiring mind needs some direction?

Thanks for helping!

Hi Tom
I agree with you,I think the 1st suspect would be bearings. Do you take pressure off the blade when not in use?

Does it have the ball-bearing style blade guides? They make a lot of noise when they’re worn.

Loosen all the bandsaw guide bearings so nothing is touching the blade. Try that. As Ellen said bearings going bad will make a lot of noise.

Have you closely checked the areas of the blade guard where the blades exits the housing of the top wheel.?
When I put my 3/4 blade on my bandsaw it made a similar noise as you are describing. I needed to do a bit of adjusting from the blade guard from where it was set for a 1/2” blade.
A 3/4 resaw blade requires greater tension and after adjusting the blade guard I spin the wheel by hand to locate any metal-on metal noises.
This solved the noise problem for my bandsaw with the wider blade. Mine is a 14” Powermatic with a riser block for increases capacity..

Does it have a foot brake.
My saw has a foot brake and it will make a scraping noise debris get stuck somewhere.

Good Luck

Thinking of it was a bearing it would have walked in squealing, just quieter, as time went along they up the volume, figuring they didn’t get your attention.

If it happened all at once, I’d check the complete path, but especially around the guides for a sliver of wood. Or just wait till the blade makes it a small enough sliver to fall out on it’s own.

Ellen, Noise is in lower part of saw, but it might be worth checking.

Greg,

Did it with the 1/2 inch blade as I put the 1/2 inch back on. Adjusted tension from lighter to heavier. Will look for subtleties. Hoping it’s not the bearings.

therealSteveN,

no squeal, hope it’s just something I missed when I cleaned the saw and set up the blades.

Did you buy the saw new or was it used? Even if you got it new, Grizzly is notorious for shipping tools with cheap ass bearings that can fail rather quick – I’ve seen them go bad in under a year on some machines. Keep in mind, bearing failure does not always produce a squeal – there are many ways they can fail. But you need to isolate the noise first, so do the suggested troubleshooting stuff mentioned and figure out where it’s coming from. Just replacing stuff hoping it fixes the problem is not the way do it!

If it does turn out to be a bearing – replace ALL of them. If one is failing, the others will not be too far behind.

Cheers,
Brad

Brad,

I like my 14 inch go555 better Was pristine when I sold it. The guy walked in turned it on and bought it. LOL!

This saw was new. It has more power and cuts better. Ive owned it for a couple years. I’ve heard the bearings on the Grizz are not the best, but????

Step by step and trouble shoot.

Bought a used Grizzly 17” BS last year with aluminum wheels. Used it couple times and it started making noise and needed bearings. Machine was only 7 years old, bearings failed a bit early for light use tool? Found cheap Chinese bearings inside everything, including motor.

The wheel bearings are super easy to change. One bolt removes the wheel. Pulls off with sharp tug. Snap rings retain the bearings and once removed, used large metric socket on bench to push them out. Did not need a bearing press. Installation was just as easy. To make it easier, place the bearings in freezer for couple hours before assembly. Grease them up, and they drop right in finger pressure. Uses a standard size sealed bearing.

Had to use bearing puller to remove the motor bearings. It took me longer to remove/install motor, then it did to swap the bearings. Used 1” PVC pipe to drive the bearings onto shaft.

easy peasy lemon squeezy

YMMV.
