Thumping Noise From Harman P61a

[GMadd]

Welcome. One more thought. Oil the 2 bushings in the fines box as well. Maybe they are stiff and preventing full movement. Should be another bushing on the outside to the right to oil. Ive used wd40 but prefer 3n1 oil.

Also use the compressed air and blow up underneath the slide plate. Youll be amazed at the amount of dust that will come out from that.

These are things that I do every time when cleaning.

Can someone help me figure out how to find these two bushings and what they look like? I want to try this. Thanks!
