Grease Level Indicators?
I see the spring, and the pretty blue and red plastic racing stripes, and I see a hole. It looks like the plunger is cup shaped, so that as grease is added, the main spring compresses and the rim of that cup raises so as to be visible through the sight hole in the red/blue plastic ... is that correct? If not, how does the 'at a glance' grease level indicator work? Thanks!
