Time

Tools Used
Screwdriver, Socket set, Wrench Set, , Patience
1. Remove front screw from base to allow it to swing away
2. Remove guard. It has a retainer ring to pop loose, then it slips off with some persuasion
3. Remove the 'big bolt' on the front of the saw which exposes the nut to remove to get the spiral worm gear out
4. Behind the guard, remove the four allen screw to remove the other worm gear. It was easier to remove this first, since it so worn. that more openly exposes the spiral gear which can be pried forward to remove.
I cleaned everything at this point, to get all the ground up bits of the old gear out of the saw to help the new ones last longer.
Replacement.
1. Install the spindle first with the big gear/bearing/seal/gasket, and replace the allen screws. I was sure I had the wrong spindle because I took this out first, and thought I should put it in last. It only came out easily because it was worn. My bad.
2. Look down the hole in the front of the saw to see that it's centered correctly. I tapped the shaft lightly to move it a bit. Not sure its really important or if it will center itself
3. Put the spiral gear back in through the front. The new spindle where the blade mounts is now squared off so you can hold that with a wrench to make tightening easier. My old 77 was round with a keyway, which is different
4. Replace the cap in front, the blade guard, and fill with oil.
5. I will have to grind away the tabs on the blade-retaining washer to fit the square off spindle, but my 77 is from around 1980 so yours may not have this issue.
I'm sure I missed something, but sequencing the reassembly was my biggest issue. You can use the parts diagram to figure out most everything else.
