A word about Oregon spindles with sealed bearings and a grease fitting.
The ones we use, and we use a lot of em , have sealed bearings, that is, the bearing is sealed on both sides. So you can pump yer a$$ off and very little, if any grease is gonna make it to the innerds of the brngs!
I verified this by taking a new unit apart.
So if ya wanna grease em, ya might wanna pop the bearings out and remove the inner seals.
Now...back to the race!
It ain't rocket science!
'Course if yer house has more wheels than yer truck...
