Hi Joe There are a number of different ways the side guide rollers attach to the guide bracket. At least one of them is mounted on an?eccentric spindle. Better quality saws have only one eccentric, on the outside?of the loop of the blade, with a concentric mount inside of the loop.? Lesser quality?saws have both guide roller bearings on eccentrics.?? The eccentric?spindle can be either:?? 1. A hollow tophat-like washer with a thru-bolt hole drilled eccentrically through it. The bolt screws into a thread in the bracket, or may pass all the way through with a nut on the back side.?? 2. The other type has a bolt that passes through the guide bracket with an eccentric (or concentric) spindle on the head of the bolt. Bearings are retained with??the bolt + a washer through the top-hat , or a circlip or even a separate small screw+washer into the stud. No big deal to replace the bearings which are normally a slide fit on the eccentric (or concentric) spindle or washer.? ?? #2 is better as you don't upset the clearance between the blade and the rollers when changing the bearings, the other requires the guideroller-to-blade clearance to be re-set?after replacement.? If this does not conform to what is on your saw, pls post a picture - jv On Sun, Feb 20, 2022 at 2:44 AM Joe Widmayer via <widmayers=[email protected]> wrote: Hello, |
