Default Gerotor Oil Pump Question

Hello all.
While disassembling a 1981 XLH motor, I noticed a slight friction while turning the top oil pump gear by hand with the oil pump installed.

Once the 4 bolts and pump were removed, the shaft spun easier.

After a disassembling and cleaning the oil pump and reassembling with new O-rings, the noticeable friction is still there when re-installed on the engine.

Is this normal and OK ?
No mention of it in the factory manual.
Thank you in advance for your help.

Yes it is normal due to that spring between the plates.
