Just bought a used MSR and working out the issues. I agree with woody's assessment as your video clearly shows a gap between the main shaft collar and the frame that increases with rpm. Push the main gear further up the mainshaft.
Looks like too much play on the main rotor shaft had same sort of problem on my msr. Found out that the main drive had moved down the shaft after a hard landing pushed it back up and it was fine.
