That was a pretty productive day.
Put the Rockshaft back on the TC. Then I got looking at the steering bolster. It was sitting there, altogether, wheels, axles, steering shaft etc...
What started out as removing some of the oily grime ended up I now the whole thing apart and cleaned up. Old paint still has to come off.
Looks like I'll be replacing a seal and a gasket or two, but looks fairly straight forward. All this little tractor so far is in pretty good shape.
