I have had this 113-298762 craftsman saw for a couple years and it has been doing well enough, but I decided to rebuild it this weekend. I had picked up new In-Line pulleys that were a third the cost and decided that I would install them and then decided to tear down the machine and clean it out. Job done and it is spic and span, lubricated and ready for work. I have never had the manual and never had need to adjust the trunion and just set it with a square now and again to keep it reasonably perpendicular to the table. I have subsequently found a dozen YouTube video's and pdf articles on setting the trunion square.
With the new pulleys and having removed the motor and motor mount I am struck by my brain fart and lack of concrete knowledge of how this is to be adjusted. I marked the two mounting rods prior to removing it and they were pushed in as far as they would go. There was no bolt that kept the motor from sliding left to right and it seemed to stay aligned by the belt relative to the pulley on the arbor. But now I have put a bolt in place and can assure the motor pulley and arbor pulley are in-line. I assume that the motor weight tensions the belt. But my question is the adjustment in length from the table that is possible and which changes the distance between the two pulleys by pulling the mount out or pushing it in. I can use judgment and be sure that it the top most raised position and lowest lowered position of the arbor there is always the full weight of the motor on the belt. But is there a "right" way to do this. I would think that there is a belt length that was spec'd for this saw and I can't find the manual on-line. I imagine this would make the optimal extension of the motor mount more obvious. Advise is welcome.
The other issue with the rebuild is finding the hex key, torx key, or what ever adjusts the set screws on the top of the table that limit the tilt of the arbor stop at 90 degrees and the furthermost setting. I have cleaned it out and maybe it is stripped but there is a set screw that is rounded out in the center and at the bottom looks like a torx of some size I don't possess or it is in fact a stripped out hex set screw. But without the manual I can't tell.
It is nice to have cleaned up this saw. It was a Craig's list special for $150 that has been working fine but now that it is totally cleaned up I have a couple questions I hope Y'all can help me with.
