Oiled holes in the assemble and all next to it. it helped but the galling sound persists. can I disassemble and clean ,polish?
 
	Will that help. Machine still runs excellent .
 
	NOTE: correction- arrow in picture pointed to wrong joint. the joint to the lower left is the noisy one.
 
	I have disassembled , cleaned and  reoiled, but slight noise still heard if run slow.
