Delta 34-670 motor pulley removal
Anyone ever remove the pulley from an old Delta 34-670 table saw motor. I have not figured it out yet. Need to pull to refurb & clean bearings (get into housing). The pulley has no set screw. Looking down into the gap (~1/16 inch) between pulley and housing, it appears the shaft is threaded…..if that’s any clue. pictures attached. If no clues, any suggestions on who may know?

Perhaps there is some info here.

Thanks, dated 1986, and still shows the retaining ring used on shaft end. I'm thinking the retaining ring rusted and fell off decades ago, and the pulley is simply fused (rusted) to the shaft.
I'm not familiar with it specifically, but with a big flat on the shaft, I don't see how it can be threaded. Could there be a set screw access hole somewhere among/between the cogs?
Typically, one would use a puller for that, but there doesn't appear to be much room between the cog and housing for one to grab onto. You might take it to a motor shop and ask if they can take it off.
The flat section of the shaft suggests there is a set screw some place. Clean off the gear and pully well so you may see how it is held together. Try some penetrating fluid where the gear and shaft meet and let it sit for a couple of days in a position that allows the penetrating fluid to seep down the shaft. After that use a propane torch on the gear, not the shaft, to expand it to see if you can get it off. Propane will get hot but not hot enough to melt anything.
