I should be putting the case back together tomorrow. I’ll have to look at the engine schematics some more but I believe the only things that belong "IN" the bottom end is a crank shaft, and a clutch shaft. Don’t remember anything else I pulled out of it. Ill also be adding a grease nipple to the clutch shaft portion of the case like so
This will aid in me applying new grease directly to the clutch shaft. To go with the grease nipple on one end ill have a relief screw on the other so
1. I can keep adding grease without pressuring the case.
2. As the new grease goes in one end the old grease will eventually migrate out the other ensuring that the grease is "changed".
The idea here is that in this engines entire life span I’ll never have to open the crank case again, it’s rather time consuming.
