2) Now remove the two screws holding the coil plate to the crankcase. Unplug the four wires going into the back side of the fan housing, and pop out the grommet. Feed the wires through the hole as you remove the coil plate.
3) Here is the seal. It probably doesn't look quite like this one, as this is the new seal already installed. The old seal is likely to be ripped and have pieces hanging out of it.
4) Carefully drill a small hole through the seal and screw a small sheet metal screw into the hole as shown. Be careful not to go too deep when drilling. Just drill through the seal and stop as soon as your drill bit drops through. You do not want to hit the bearing under the seal. There is a space between the seal and bearing, just don't be bearing down so hard you fall through into the bearing. Grab the head of the screw with visegrips or a small prybar and pop the seal out.
5) Clean everything up and inspect the bearing. It should look something like this. Squirt a little oil on the bearing to prelube it, put oil or vaseline on the sealing lips of your new seal. Tap the seal in place until it looks like the seal in the third image. Reassemble in reverse order. Torque the flywheel nut to 53 ft-lbs.

Not sure how this got missed.

No it's not the same job. The G1 engine is a 2 stroke, And the G16A you have is a 4 stroke engine

Good Information

I know this post is a bit old. But I used this info to get to the seals in my friends g1. His seals and bearings were shot so I had to split the cases. But anyway. I recently bought a g1 for use while camping. It had been sitting for 10 yrs so I disassembled to inspect/replace the seals as a preventative measure. However the seals look great. But.... the fan side seal seems to be set in a lot more then both this write up and my friends seals. His cart Is a 1983 and mine is a 1982 however from what I have found the 82 lower end and block are the same as other g1.

I just did mine and the lip for the seal is wider than seal. I just set mine so it was fush with the out side of the case. My flywheel was pain to get off had to heat with a torch several times.

Both flywheel on mine and his cart came roght off with the puller. Havnt had to much that was a pain on either cart. Just wanted to see if anyone else had the something with there seal as the last cart didn't have this lip.
