I have an arbor tool from Pelican that I have used before to install the main seal, but for the life of me I cannot figure out how to use it this time. There are 4 pieces: the threaded mandrel that bolts to the crankshaft, ring, the part that is pushed with the nut that threads down the mandrel. It seems like something is missing with the tool or you don't use all the pieces.

Update: I it figured out. I forgot the extra piece the ring) that comes with the arbor is only for protecting the edge of the tool when not in use. Now I need to know who supplies the best seals or is there any difference. I don't want to be doing this again.
