This morning I was making a cut and needed to angle the blade on my Unisaw, at about 20 degrees it has a slight bind, I took the motor cover off and peered around underneath and can’t find anything stuck or binding anywhere. I noticed this a week ago as well but I couldn’t get it to happen again, now it happens every time I tilt the blade if its 1.5” or more. I did recently install a new 4hp motor but everything around the motor is clear. I used a very bright flashlight and looked at everything I can see from the bottom while my daughter tilted the blade and i cant find anything. I really dont want to have to pull the top off the saw. Have any of you ever experienced this?

This may sound like a stupid question, are you using the standard table insert? Have had the occasion where blade was rubbing on the table insert.

And the other thing would be the alignment of the motor pulley or the loosening/slipping out of correct position of the motor pulley on the motor shaft..

This is fairly typical on even the better saws.
Unfortunately, it requires perhaps shimming the trunion mounts to correct. Somewhat easier on cabinet saws “table removed”, more of a job on contractors saws.
If its out alot, it is a dangerous condition, that should be fixed.

Before you do anything crazy, make sure you raise the blade before tilting it. My Unisaw will not tilt without the motor hitting stuff unless the blade is raised.

Thanks for the help guys! I think I found the trouble. I took the top off this morning and found a little bracket on the end of the tilt gear (for lack of the proper name) was shifted out of place, it’s an aluminum piece that bolts up against the end, here’s a pic after I corrected it, it’s the part I’m pointing at.

It looks like it could be worn but I can’t tell exactly what it does. I also found the there is about 3/16th” of play between the collar on the angle adjusting shaft,

I was hoping to slide the collar over but it and the gear on the other end of the shaft are held in place with roll pins, is there any way to adjust this? It’s doesn’t seem to be a problem other than having about 1/4 turn of play when I crank the hand wheel. Should I be concerned about this?
I blew of all the saw dust and cleaned all the gears with some carb cleaner while I have the top off, now I’m looking for some lube that won’t let to much saw dust stick. Thanks for any suggestions!
