Topic tags/keywords: question

So i had a tire come off a 17” grizzly on friday. Installed new grizzly urethane tires today, and blade flutters when I turn off the saw and it begins to slow down. Basically, tracks ok and probably useable when up to speed, but no matter how i adjust the tension or tracking at some point it gets a bit squirrely. Any thoughts? And no, i haven’t called grizzly tonight…Thanks..

I can’t imagine any reason for blade flutter other than loose blade tension.

So i’ve tried two sets of new tires ( grizzly’s suggestion) still can’t get the vibration out of the saw/blade…Replaced the belt with a link belt , just for kicks …No luck.Blades track good, but definetly some vibration going on. Blade looks and sounds fuzzy when up to speed and gets pretty squirrely after i hit the off button..Grizzly only talks of the tires. Any thoughts on what to look at next ? thanks

Did you glue the tires on? Pretty much anything over 14” should be or you get weird behaviour.

Cheers,
Brad

Sounds to me like you may have a kink or problem with your blade IF it is tensioned properly. Have you tried another blade? I have that 17” Grizz and glued the original tires on after it threw a tire after I did something stupid.

I appreciate the response gfadvm. I have tried 2- 1/2” wood slicers Checked both with a straight edge @ the weld and thought they looked good….Again , it tracks good. But the saw sounds and feels a bit rough..I feel mabye i screwed something up when the original wheel came off..I am definitely no wiz but have had the saw for about 5 years and think i understand tensioning, but i will continue to fiddle i guess..

Do you have any vibration running the saw without the blade? That would be a bearing/belt/pulley issue. And it takes the upper wheel out of the equation. You should be able to diagnose this problem in a step by step process of elimination. The next step after no blade would be to back all the guides completely off, track the blade by hand, and turn it on to check for vibration. Keep us posted.

My little Ridgid vibrates a lot but doesn’t affect it’s performance (just irritating).

Seems pretty smooth with no blade installed, penny stays on edge while running, so maybe i should focus on the upper wheel…Bearings and guides have been backed off the whole time.. Thanks for the feedback..

Don’t glue urethane tires, right?

Yeah, sounds like you need to focus on the upper wheel assembly and the blade. Do you have a different blade you can try?

You absolutely can glue urethane tires… might not be necessary for 14” or smaller though (although I know of several people who had to due to slippage). But once you start getting larger, they can (and do) slip, bunch and can even be thrown off completely if not glued in place. The larger the wheel, the more it becomes a problem.

Cheers,
Brad

Thanks Brad, this is where things get confusing, Grizzly say’s no glue, A second tire company i bought a third(orange) set from say’s, no glue..Not doubting you Brad…Imstarting to think i threw something off when the original tire came off…

ok -since you still have the issue .loosen the motor belt tension so it slips slightly when you turn it on .just try this . i may not understand totally the problem but if this fixes the problem it is an easy fix .
