The Original Shellplate Bearing Kit

These kits help you get the most from your Dillon reloading machine.

How the Shellplate Bearing works:

As the Shellplate bolt is tightened there is additional friction between the shellplate and the press. The shellplate bearing overcomes this friction. This stabilizes the shellplate and reduces run out. This will dampen the motion of the shellplate, reducing powder spills as it moves into position. You will also experience a better feel for each operation. Decapping, priming, and seating each have their unique feel. You'll know when a primer isn't right. With the reduced run out, case overall length will be more consistent. The result is a better operating press, consistent ammo, and increased run rates.

Lubricate the bearing with a little grease, don't pack it like a wheel bearing. If the grease is collecting gunpowder on your press that's too much. We use Mobil 1 or Slide-Glide.

We used to sell the oil-lite thrust washer kit. Feedback from our customers told us it wasn't a good value. The needle bearing has a far greater range of bearing preload making it much easier to tune precisely. We still have a pile of these oil-lite washers. If you want to try one send us a message before you order, we'll add it to your order for 25 cents (fits 550 or 650). Then you can decide.

How the Low Mass Detent Ball & Reduced Power Spring works:

Our Low Mass Detent Ball for the Dillon XL 650, SL 900, and RL/Super 1050 is tough as nails. This phenolic ball is super hard, smooth and lightweight. It's approximately 7 times lighter than the factory steel ball and every bit as tough. The low mass detent ball has less momentum when it locks up with the shellplate. The material also absorbs vibrations much better than the steel ball. This detent ball is highly abrasion resistant and will not be cut or scared by the shellplate. These are industrial grade and used when strength and abrasion resistance is required.

Both the low mass detent ball and reduced power spring are custom made to our specifications for this purpose. We didn't settle for off the shelf products that are close enough.

To install, remove the shellplate, pluck out the steel ball and OEM spring. Clean any debris out of the channel. Drop our Reduced Power Spring and Low Mass Detent Ball into place. Then reinstall the shellplate.

How the Camming Pin Bearing works:

The camming pin bearing replaces the camming pin on your XL 650 or SL 900. This is a sealed bearing, as such, no maintenance is required. It smoothly rides the case insert slide cam. You won't need to lubricate the cam to prevent wear, resulting in a cleaner press. To install remove the locknut with a 9/16" wrench, unscrew the original pin and screw in our camming pin bearing. Each half revolution of the camming pin bearing is .020" of adjustment. Before you tighten the locknut ensure the bearing rides square on the case insert slide cam. Use a 1/8" allen wrench in the hex at the end of the pin, to hold it steady and aligned when tightening the locknut.

We match the dimensions of the OEM pin. Our pin fully supports the casefeed arm, reducing vibrations and unnecessary wear. Reduced vibrations helps to keep cases correct side up when using a casefeeder. This is an exclusive feature of our pin, not available from any other manufacturer. We make this camming pin here in our shop, using tool steel.

Ultimate and Premium Kits:

Our Ultimate and Premium kits come with an assortment of screws, knobs and washers specific to your press.

Large knobs fit over the nut of the powder adjustment bolt. This makes adjusting the powder drop a snap. The included label indicates which way to turn for more powder and you won't need a wrench. It may take a day or two for the plastic to form to the nut, or you can warm the plastic a little before installation to speed up the process.

Thumbscrews are installed on the powder measure clamp. You will find not needing to reach for an allen wrench while adjusting the case bell makes the process go faster. Nylon washers are installed under this these thumbscrews. To stay tight they must sit flat on the powder measure clamp. These will need to be fitted, use sandpaper, a file, or grinder to create a small bevel on one side.

Depending on the kit ordered you may receive a primer alarm screw, Dillon recently changed the design of the primer alarm and it no longer accepts a machine screw. If this is the case, repurpose the screw. You will find that it fits as a tension screw on your Blade-Tech holster.

Thumbscrews are also provided for the case insert slide cam (650) and the die clamp screw (650 & 1050)

Additional Information:

No re-adjustment of dies is needed with any of our kits!
