I bought the Craftsman Radial Arm Saw model 315.220100 (RAS) from a guy off the internet and brought it home. Played with it for a few days and the control cut (carriage auto-retract) unit quit working. I could not make the carriage move without disconnecting the cable; so i did. I put the saw aside and worked on other things for about a year. I would like to restore the functionality to the RAS but don’t know how the unit is supposed to work. Inside the control cut head, the motor turns the shaft and turns the pulley that has the cable attached. The motor turns the shaft to the left, so when looking down on the RAS from above, the direction of rotation is clockwise. This is counterintuitive because when the wheel turns in this fashion, the rotation of the wheel pulls the cable away from it’s normal alignment, which goes thru an eyelet and parallels the rail. I have disassembled the control cut motor/gearbox assembly and there does not appear to be any malfunctions in the components – i.e., nothing appears to be broken. When reassembled, all parts still work – at least the motor turns, the shaft and the pulley then turns.

I think perhaps the clutch assembly (the pulley that has the cable attached to it) has failed and does not allow slip in the correct direction of rotation.

Sears says the part is obsolete and no longer available. Short of buying a junked saw and use the parts from it, i don’t know what else to do other than unhook the feature.

Any ideas?
