There was a recent thread on this and rather than repeat all that was said there, just read it. http://shopsmith.net/forums/showthread. ... on+bearing

Be advised the usual cause is inadequate lubrication of the upper sheave. Plan on doing a tear down and cleaning and oiling everything before trying to operate. Also check the pork chop and do Bill's repair, which is discussed in the link you will find in the above thread.

The tension pin goes in a hole in a button in a bearing at the end of the control sheave. The u shaped piece(with spring like 'roller') goes in the ends of the tension pin. The spacing of the ends of the u shaped piece should be close to the length of the tension pin(if too much greater, squeeze them back).

Now as to the cause of them coming out.

Lack of lubrication, and/or turning the speed dial with the pulleys stationary(not rotating).

Add Lubrication of the control sheave(and the floating sheave[on the motor shaft]) to your cleaning(and reassembling) task.


So another journey begins.:cool:;):)

No, either movable sheave can cause this. The loop should NEVER be pulled by the porkchop assuming the sheaves are adequately lubed and the control knob operated correctly(slowly towards slow).

Good info in that thread, but do not choke on it!:D
