 Seal
This shows the v-ring seal and the method we use to grease and install it.
To keep grease off the shaft during installation of the v-ring shaft seal I found this dental pick at the pharmacy. The curved shape allows me to get into tight spots with accuracy. Lay down a nice bead of grease in the seal race. This is a standard axle grease. I made this simple tool to install the seal. It's a piece of round stock with a 0.65 inch hole bored through it. A piece of wood with a hole drilled in it would also work.

Slowly press the seal installer all the way down to the hub. The depth of the seal race provides the proper lip compression of the seal. Simply push it down and it's installed perfectly. This is the installed v-ring. This should be kept greased to ensure a long seal life.
