question re: impeller installation

[EricS.]

Hello all, first post here. Great forum; I look forward to asking you many stupid questions!

I just installed a new impeller in my 2000 XP. I noticed that when reinstalling the cone on the back of the pump there was a little resistance, and I understand that there is a plate inside to keep tension on the impeller shaft. Naturally, my first instinct upon finishing the assembly of the pump was to try spinning the impeller (with pump still on the workbench). It spins smoothly, but not exactly how I would have thought. It won't just spin freely after I pull my hand away. Is this normal, due to that tensioning plate? I don't really remember how easily the old impeller spun prior to removal.
I want to take her out for a ride in the morning to see how the new impeller performs, but not if something isn't right......
Thanks in advance for the help!

Eric there is a spring inside the cone to keep the shaft from rattling in the cone. As long as you torqued the impeller to spec and did not pinch the thrust washer it should spin easily without much force.

it should spin freely, but due to the physics of friction and viscosity of the grease in the bearings it will not just sit there and keep spinning for ever (if even 20 seconds)
