Craftsman Table Saw Problem-

Older table Saw: Mod 315228390

The shaft controlling the bevel angle of the blade unscrewed and came out. I can screw it back into the "Knuckle" (nomenclature from the Parts list in the Owner's Manual) and it will move the blade past the 90 degree position, but it will not pull it back to less than 900 further more to 45 degrees where is where I want it.... It appears as though there should be a retaining ring or something on the end of the shaft but there does not appear to be a groove to hold a retaining ring and the shaft does not appear to have been sheared at the end.

Does anyone know what holds the shaft into the "Knuckle"

Thanks,

I am going from memory here, it is a while since I have worked on one of those saws.
Check where the shaft goes through the frame on the side, the bearing there may be loose or worn and is allowing the shaft to move in or out instead of pushing on the knuckle to move the blade assembly.

I had been looking for a retainer ring at the inside end of the rod but no luck. At about 2 this morning, I thought what you mentioned. When I got up - no, not at two - I went to my shop and checked. No, there is nothing there and no signs of there having been something there to hold the rod...We are bot wrong....:-(

thanks for the idea though

There is a ball on the adjustment rod that rides against an indented bracket (item 23 in the parts view). The ball probably came loose from the rod.

No, the ball is an integral part of the rod and that - and the bracket - is what it pushes against to tilt the saw blade in one direction, but going the other way, there is nothing to "push" against and the rod just comes out....:-(

According to the measurements on the Craftsman website, the rod is 113.7" long. Measuring mine, it is only 12.8" long. It does not look as though it has bee broken on the end but it must have been. I have ordered a new one to check against the one I have - I can always return it if it is not the problem....We will see ...as soon as I get the part...

Thanks for the suggestion/idea

Rgds,

Larry

There has to be a flange on each side of the ball on the shaft to hold the ball in one place so it either pushes or pulls the blade mechanism.

113" is wrong - the saw is only 20" wide. The ball is captured between 2 indents (dimples). It's retained by the bracket on the inside of the cabinet and by a matching indent in the cabinet itself. If the rod can come out then either the saw was assembled wrong or the dimple in the cabinet is badly worn.

Unhappy Ooooops

13.7"....got an extra "1" there - my error...

Yes, there is an indent on the side of the cabinet that catches the bal for when it is pulling that way. No, there is not bracket to hold it from the other way. I have had the saw since it was new and haven't had any problem - until now. I admit, I do not remember seeing what was holding the rod for the other "psuh" direction but there is no bracket on the outside that holds the ball....

Since you have ordered a new rod, I assume you've been to sears parts direct dot com. In the "blade" parts list, item 22 is the rod and 23 is the bracket. The ball on the rod is captive between the bracket (on the inside) and the cabinet (on the outside).

According to the parts drawing, it appears as though the bracket is on the inside of the ball...reinforcement for the cabinet to hold the ball.....Examining the cabinet, there are no holes/bolts/or other indications that there ever has been a bracket on the outside of the cabinet....;-(,,,, Not home right now - gone for weekend - will check it Monday,,,
