Hey everybody. Gotta constant wistle from the fin. The longer the copy run the louder it gets. Removed all fin covers & lubed all bush. & bearings. Even some clutch & motors' bushings. Still wistles.
Also getting a heavy squeek when Mach stops but fin still putting out prints. Help with noise.
Thanks

What finisher model do you have? Most squeecks seem to be caused by the white plastic rollers that run with spring pressure. The shafts usually need cleaned/lubed.

Turns out it's not fin. It's drum blade on drum. So I moved it away half way to buy me time. Got 2 Mach with same problem.
750, I changed blade. Not oem. Noise came back fast. I came back with whole process unit & swapped blade ass'y but kept new blade. Same wistle. Manualy, almost impossible to turn. The other unit no problem turning manualy.
I swapped process units & done.
Is it something that deforms in clng unit or blade.
Ps. The unit today, had a very old burnt out blade so I don't think oem or none oem doesn't matter. I don't know.
