Doing further research, I see that I need to install the rest of the assemblies, including the pump with no o-ring for ease of removal. Then measure total endplay with my Starret dial indicator. If I fall within specs, then I'm good to go. I've installed the intermediate of the three thrust washers first.

Endplay comes to .030 with the intermediate of the three washers installed. I'm searching through all my publications to find out if this is within spec. If anyone has specs around please post so that I can confirm.
