Eric,
Will do. I’m slow , you know that, but I’ll keep posting updates.
I’m very much of the mind set, I don’t care if the engine ain’t great, just needs to do summer. The trans probably needs refresh soon. Maybe it’s going to be subie and freshened trans over the winter.
I need to cash in my work credits to pay :-)

If not damaged or worn leave it. If replacing use a bearing heater to heat it enough that it doesn't need to be pressed over the hub. Be sure to use the correct o ring on the crank.

>>> For the flywheel seal there is a bit of a design flaw here. For the oil outside of the bearing to return to the case there are two small channels, one above and one below the bearing. Maybe the goal was to keep oil there to reduce the wear of the thrust shoulder? Sloppy rebuilds will sometimes have these channels block with sealant and overtime they will collect carbon and get blocked. I've seen them blocked enough for the seals to get quickly pushed out. My fix? Look at a type 1 engine case. You will see a hole, at about 8 o'clock, 5/32" drilled at an angle for the oil to return. Drill one. I go down a bit lower to make sure I clear the case stud bores. Drill a little at a time and blow out the chips until just breaking through. A few won’t hurt anything. The perpetual flywheel leak will be no more.
>>>
>>> For the trans input shaft, rarely is the leak due to the seal. Overfilling, overheating, worn shaft or pilot bearing, or the slinger in the bell housing is loose-damaged. With the seal out check the bushing you can see. If it moves it t needs to be repaired.
>>>
>>> While it is out, grab the input shaft and push-pull it very hard. If it moves find out why. Usually this is due to the main ball bearing moving in the gear carrier housing. If while driving in 3rd gear gently push the shifter forward and work the throttle. If the shifter is moving with the throttle this is the cause. At some point this will grow to popping out of gear especially 4th or if bad enough other damage.
