Yesterday I tackled a bit with the starter. Not that it really needed obvious attention, just if it`s out I thought I look into it.
Came apart easily. No need to replace anything, after some cleaning and regreasing everything can go back together.
Transmission gears run on needle bearings. Pretty thoughtful.
This is kind of odd, grease seems to be migrated from the gears while sitting during the 11 year long nap..
After a bit of cleaning:
Planetary gears regreased:
A 24 mm socket helps holding the brushes during reassembly.
Done.
