Is is possible to adjust the lash on the hook gear set on this machine?

I did adjust the foot lift (using the wingnut at the back of machine). It does not seem to make any difference. But I don't think it's that since it makes the exact noise with needle unthreaded, foot in the up position.

I have run the machine unthreaded with the presser foot up, it makes the exact same noise. After purchasing the machine, I cleaned it and thoroughly oiled directly every part reachable that moves against another part , plus all the oil holes. I've physically moved every linkage in the head and everything is tight with no play. Same with the walking foot linkages at the back of the machine. The only part that really has any play in it is the presser foot linkages at the back of the machine that go to the knee lifter, but I've held on to those while running the machine to dampen any possible vibration and it's not coming from there. I've subsequently examined the bottom of the machine more thouroughly and everything is very tight except for one thing: I noticed the gear that is attached to the hook shaft has just a tiny bit of play or backlash. I can just barely detect some rotational movement of the hook (the actual hook not the bobbin case) but it's really a tiny amount, like you can't really see it but you can feel it. I'm not sure if there is supposed to be zero backlash at that gear. If so I don't see how to take out the backlast. the gear is tight to the hook.

Hopefully this works

Hmm, could you try it again? I'm not super familiar with facebook, the link works for me but maybe only I was able to see it. I pressed the "share button" so maybe it will work now. I tried to post the vido here but even though it is only like 16 seconds long the file size was too long.

Hello, I recently aquired a Juki LU 562. It is sewing great but at higher speeds makes an irritating higher pitch vibrating/chattering noise as if something is loose. It's hard to tell but it appears like the noise is coming from the head area, maybe where the walking foot mechanism is at the back. I've gone over the machine and can not find anything loose. It's hard to describe the sound so I've attached a link to a video. I don't think this noise is normal. Does anyone have any suggestions on what to check? Thanks! It also makes the same noise when not sewing anything with the presser foot up. https://www.facebook.com/61560928232099/videos/513472158205034
