The factory may have assembled the shaft, the gear, and the bearing carrier sleeve and pressed them in.
If there is no bearing carrier sleeve then they may have done it some other way
But like I said, you can rotate the gear into an advantageous position then use some short lengths of metal rod
slightly smaller than the pin and a small C-clamp or Channelock pliers as a squeezer to nudge the pin out little by little.
Use several pieces starting with a short one like 1/8"
It works

Oh well, in that case you can make a new shaft from mild steel pretty much from measurements of the saw:
If you have both blade wheels then you would have to match the bore of the driving wheel,
then pick a bearing size (use bearings sealed on both sides). Select a shaft length based on the position
of the worm gear and the desired position of the driving wheel from the back section of the saw body.
Lastly, you would match the inner diameter of the bronze worm gear (worm wheel)
The Grizzly parts list might have the bearing size listed
You could also buy the shaft from Grizzly I suppose, but making it yourself would guarantee the fit

Some saws use a carrier sleeve (like a short piece of pipe) which carries the bearings and shaft; it's pressed into the saw
body from the back. Mine is like that, it's 1978 vintage
Other designs I believe have the bearings press directly into the saw body- newer ones I think are like that, to save cost.
