This kit includes everything you need toconvert your Powder Bar to a Micrometer Powder Bar.This conversion kit is compatible with all Dillon PowderBars (Extra Small, Small, Large, Magnum, BeltedMagnum* plus the SL 900 Shot Bar*).* The Belted Magnum powder bar and SL900 Shot Bar require minormodification. See Note in Step 4 of instructions.Before beginning installation, it is recommended thatyou read these instructions completely at least twice. Itis also recommended that you review the factoryinstructions and exploded parts diagram for your DillonPrecision Auto Powder Measure. If you do not havethe instruction manual for your press, manuals areavailable for download at the Dillon Precision web site.(www.dillonprecision.com)* Dillon Precision does not authorize the Micrometer Powder Bar Kit™for use on any of its reloading presses and its use may voidmanufacturer or dealer warrantees.If you have any questions about installation, operation or experience any problem with your micrometer, please callme first. I can often resolve the problem over the phone (480-216-2041 cell). – LeeStep 1: Place an Index Mark on Powder BarThe Auto Powder Measure is oriented differently on each Dillon press. Beforeremoving the powder bar, decide from which side you will want to view themicrometer when adjusting the powder charge. As you are facing the press, you willtypically adjust the micrometer from the side shown below.• Square Deal B – Left Side • XL 650 – Left Side • Super 1050 – Left Side• RL 550B – Right Side • SL 900 – Right Side • AT 500 – Right SideMark a line on that side of the powder bar, near the adjustment screw, with a pencil,white crayon or other marker that is easily visible but removable. This line will beused later to orient the micrometer index mark for easy reading. On the XL 650 andSquare Deal B you will notice that the micrometer numbers will be upside-down. Butthis orientation will be much easier to see during adjustment than if it was orientedon the opposite side of the powder bar as with the other presses.Step 2: Remove Powder BarRemove the Powder Bar from the Powder Measure. (Refer to Auto Powder Measure instruction manual for details.)Step 3: Disassemble the Powder BarNOTE: Before disassembly, look closely at the Powder Bar and note that Powder Bar Inserts (Ex-Small, Small andLarge) and some Powder Bars (Small and Large) have a flat side and a side with a cavity. The cavities must alwaysbe on the bottom side of the Powder Bar.a. Remove the Powder Bar Post. Press the bolt head against ahard surface to compress the spring washer while pulling outthe Powder Bar Post. The Belted Magnum powder bar andSL900 Shot Bar have a 3/8” set screw instead of a powder barpost. Remove the set screw using a 3/16” hex key.b. Remove the Powder Bar Adjustment Screw.c. Set aside the Powder Bar Adjustment Screw, spring washerand flat washer. They will no longer be used.Step 4: Prepare the Powder Bar for Installation **The Teflon coating must be completely removed from the hole in the end of the powder bar where the adjustmentscrew was removed. Use a round file or rolled up sandpaper to scrape away the Teflon coating, leaving a fresh baremetal surface for the LocTite to achieve a good bond. Clean the hole with rubbing alcohol to remove any residue.Note: If you happen to have a 7mm thread tap, it does a quick job of cutting through the Teflon coating and exposing clean bare metal for theLoctite to achieve a solid bond. Only a 7mm tap is the correct size. Do not substitute any other size metric or SAE tap.** The Belted Magnum powder bar and SL900 Shot Bar adjustment screw hole is smaller than on the other powder bars and must beenlarged using a 17/64” drill bit before installing the micrometer. Some older Small and Large powder bars may also require enlarging.Applying index mark (XL-650 shown) |
