Super 1050 Indexing Adjustments

Sep 29th, 2016

If your Super 1050 is not indexing properly perform the following checks:

  • Loosen the 4 cap screws on the shellplate lock ring, and spin the lock ring up.
  • Lift the shellplate up. (no need to remove the toolhead, just guide the plate over the toolhead pins). Now you can see the top of the index lever and pawl.
  • Visually inspect the pawl for damage.

It could be that the primer arm/cam assembly is not low enough, where it is clamped around the black steel primer shield. Follow these steps to properly adjust it:

  • Pull the handle down on the machine, and manually manipulate the primer slide so the alignment pin goes into the hole.
  • Now, loosen the clamp screw on the primer arm/cam assembly, and slide it down until it bottoms out in the track that the primer slide is in.
  • Now back it up only .010", the thickness of a business card, and snug the clamp screw.

Depending on the age of your 1050, you either have a brass roller on the rear of the primer slide, or a roll pin with a rubber sleeve over it.

  • If you have a roll pin and no rubber sleeve, it has torn off.
    • Go to your local auto parts store, and buy six inches of 1/8" automotive vacuum hose.
    • Press it over the exposed roll pin, and slice off the rest.
    • Absence of the rubber sleeve can cause slide movement problems.
The base of the primer feed body has a vertical notch in it.
  • This notch must face rearward.
  • The primer feed will bolt on facing either direction. Be sure this is oriented correctly.

Be sure to lightly grease the underside of the shellplate lock ring, where it contacts the top of the shellplate.  This makes it much easier to set the proper tension on the lock ring.

Check the bushing which guides the swage rod is inserted up into the underside of the frame.

  • The top of this bushing should not protrude above the surface of the frame where the shellplate rotates.
  • You must remove the shellplate to inspect for this.
    • If too high, use a large-diameter brass punch and a light hammer tap to move it down to flush.
    • This bushing is held in by green Loctite.  If you hit it too hard and knock it out, just clean the bushing and hole with solvent, apply more green Loctite and tap it back into position using a brass punch.
