My 113. TS beagn making some funky noise about a week ago. The blade was nicking the zero-clearance insert, especially during start-up and shut-down. I tried a different blade with the same result. I checked the belt for wear, then removed the belt and checked the arbor/bearings for any obvious sign of degradation.
As I spun the blade I could hear a very faint clicking sound. The noise was nearly inaudible, but the saw is 20 years old, and as far as I know, the bearings have never been changed out. At this point, I’m thinking the bearings are shot, but I also checked the arbor for run-out and ran the motor under no load- just to rule them out. Both checked OK.
So case closed, bearings must be the issue. Couldn’t possibly be anything else. So I found some bearings on Ebay. Four 6202ZZ bearings for $12 shipped. Four bearings was only a couple bucks more than ordering just two. And I figured it would be good to have extra in case I futzed one of them up during installation.
Barely two days later I realized that in my haste, I ordered the wrong bearings. I needed 6202ZZ-10 (10 denoting 5/8” bore). So I ordered four more from the same ebay seller. I didn’t bother asking the seller for a return, due to the fact that my stupidity caused the problem. Not to mention it would cost me more than it was worth to mail the package back to the seller. And today, both envelopes arrived in the mail.
I immediately went to work. Unplugged the saw, removed the blade, and removed the motor. I then decided to brush out some of the dust from the saw’s interior before I went to work removing the trunion assembly. When I went to clean the area around the arbor pulley, the pulley almost fell off!!! Apparently, some bonehead left the set screw loose when they aligned the motor and arbor pulleys a few weeks ago. DOHH!!
So I tightend the set screw and put everything back together. The saw runs perfectly.
