Dillon 550 question...

Set screw in the bottom of the ram holds the transverse pin in place.

If you remove the plate on top of the ram, it should be re-aligned with the dies. Dillon makes a simple tool for this.

The oldest ones had e-clips holding the swing arms on, the newer ones have nylock nuts. The very oldest ones from the 80s didnt even have oil holes. The upper pins in the swing arms disassemble inwards in only one sequence.

Check for cracks in the knuckle and wear in the swing arm pivot pin holes.
