Table Saw Pulley Slipping

Sam,
I have the same saw and I did have one of the pulleys, on the arbor side, come lose. I meant to put a little dab of Loctite (I think the blue is not the permanent one) but didn’t do it yet. This got me into the habit to always check the TS before I start it up. As for the binding issue just make sure when you raise the blade (all the way up) the pulley does not touch the undertable. If it does it needs to go in a little more. To check, rise the blade all the way up and then try turning the blade by hand (of course unplug the saw before you do it). I am using the original belt too, and I tried to align the pulleys as good as I could. It passed the coin test, so I’m happy. I hope this helps.

It is not unusual for pulleys to get loose. Tighten the set screw—after you make sure the 2 pulleys are still aligned. Make sure the key is there if it accepts one. You probably should also change the belt if there is wear or cracking. I prefer the cast iron hub and sheave type pulleys to the cheap ones that come on many cheaper saws. They lock down much better and run smoother. The bad news is, they are not cheap, but I think they are well worth it.

I really don’t think the pulleys will fly off. I’ve had a bunch come loose, but never lost one.

If the sheaves come off they won’t come at you. I had one on a band saw rub hole in the belt guard though. Machines steel sheaves are the best and that is what I would look for. Those cost me about $15 each. A new belt would be a good invenstment. I use a good quality regular belt. I have never used a link belt with but they are supposed to be good. I see no need if I use good sheaves and the saw is smooth. I am sure many will disagree. A set screw called a “Bulldog” set screw can be bought for a few cents. These bite in and don’t easily come out.

Thanks for the advice and comments. I have a PALs kit, A-line it system and new pulleys and linkbelt on order. My timeline of getting to it this weekend is not going to happen, since I have yet to recieve my shipment. In the meantime, I will try to adjust the saw to get it operable.

thanks,

something else to think about , i sometimes remove the allen set screw and sharpen it to a point so it bites into the shaft or tighten the screw and add another screw behind it sort of like double nutting a bolt.

I think the bulldog screw has an end that prevents the loosening. They don’t like to come out so get it right the first time.
