look at the photo where the brass piece is completely separate, no old rubber on it.
right of it, short chrome piece with notches to receive/retain the flange, and keep the brass piece from rotating after assembled.
the flange stays on. push the threaded end of the brass thru the short chrome piece. the flange and notches now mated.
put the short chrome piece into thew hole in the back of the pivot. verify no physical contact when arm is moved in all directions.
tighten set screw fixing short chrome piece.
slide the two layer grommet past the threads onto the brass piece, the smaller forward layer pressed into the short chrome piece, now invisible.
the second layer of the grommet is against the rear of the short chrome piece, visible, the part of the grommet that is always visible.
spin the entire rear counterweight assembly (it has internal threads) onto the threaded shaft of the brass piece.
rotate the assembly forward until it is snug to the rubber grommet.
tighten set screw.
assembly complete, entire rear assembly totally isolated from the front by the rubber grommet.
now, the balance and stylus force can be made using the movable weight collars.
