If you had the primer feed apart recently...
If you had the primer feed apart recently like I did, to change the feed tube and cup size from small to large or vice versa, then you probably already wiped the stage where the primer feed assembly bolts to the press. If so, the install of this ball bearing roller will be greatly simplified. Just loosen the two screws with the Allen wrench and push out the blued steel primer track plate from left to right using the tip of the new track plate. Slip the new one in and check the clearance at the ram. If it is not rubbing the ram you can proceed. Set all the way left and attach the ball bearing roller. Check for alignment and snug the bolts. Test the stroke and adjust to center the cup in the shellplate. See if the bearing roller is turned by the stroke. If not, loosen bolts very slightly to correct center alignment and assure the roller is turned by the stroke of the primer feed bar. Re-tighten. Done. If you have not had the primer assembly off for a while then remove it and clean before installing the new primer track plate and roller. Great fit and finish. Fast install too.Verified purchase: YesCondition: New

It worked for me after a little bit of revision.
My older 550b frame has the over cut in the bed area. So the support roller would not contact the primer slide. I considered the brass shim but after experiencing difficulty holding the bearing assembly in the slot while manipulating the parts, decided to deepen the slot and just allow the PSBTP lay against frame. SUGGESTION WIDEN PSBTP AND HAVE AN ELOGATED HOLE TO CAPTURE THE BEARING ASSEMBLY. I dropped the bearing assembly several times, etc. it’s just difficult to manipulate the parts. Its fine but complicates the set ups I recommend this accessory after you tried replacing the control rod and setting up per Dillon. And still didn’t get satisfactory primer drop.Verified purchase: YesCondition: New

Smooth Operator
The primer system on my Dillon RL550B has been giving me issues for some time. I've loaded many thousands of rounds and periodical cleaning would typically resolve issues with the primer slide mechanism. After many years and many many thousands or rounds loaded, the cleaning would no longer resolve the problems. A slight nudge of the bar was required to get it to go fully forward. This Primer Track Bearing Kit fixed the issue. I've since loaded several thousand more rounds since installing the kit. The primer system is now functioning as it did originally, smoothly and independent of a manual nudge. For under $30, the investment was well worth the expense. The folks at Dillon tell me that the culprit is a slight bulge in the aluminum slide bar that occurs over time. If you send it back to Dillon, they'll repair the issue or replace the slide bar component. Or you can install this nifty invention yourself and be reloading again without the hassle of returning the primer assembly to Dillon. Dillon is awesome. They always step up and honor their No BS warranty. But this kit avoids that necessity and actually improves an already impressively well engineered piece of equipment.Verified purchase: YesCondition: New

Physics
I felt the price was high initially until I realized that it not only solved several wear issues it reduced primer misfeeds. The design of the Dillon RL550B that I have (I am not sure of the C model changes) uses a primer feed design that does not balance the primer bar loading well. The die cast guide shoe will see lateral wear due to use, mine already had wear. This product solves that unbalanced high stress lateral loading, the primer bar extended support also aids in smooth motion. After recieving and installing this product, the quality is exceptional, the fit and function was great, well worth the cost.Verified purchase: YesCondition: New

All owners of a Dillion 550 press need to purchase this item.
The track plate installed quite easily and functioned perfectly. The provided instructions are easy to follow and provided additional information to enhance and ensure proper operation of the overall primer bar function. If anyone has a Dillon 550 Press I highly recommend the purchase of this upgrade, you will never regret the purchase. Immediately after installing the track bearing plate I loaded 3000 rounds of 9mm and never had a primer bar feeding issue. Before the tracking plate install I would have 10-20+ primer bar hang ups out of 3000 rounds which is very frustrating and time consuming. Very happy with the overall operation of my Dillion since the install of the primer tracking plate.Verified purchase: YesCondition: New

Little thing that makes a difference.
This little addition to my RL450....yes it fits the RL450....RL550.......makes my machine a bit smoother. So far I have had no primer feed problems after 5,000 reloads. That is a lot different from my previous experience....every 150-200 rounds I end up with a primer that did not feed correctly even though I cleaned my machine after every 1500 rounds. This device makes the primer feed a lot smoother and a lot more precise as it supports the bottom of the primer feed bar quite a bit better than the factory set up. The roller bearing keeps the bar in position so that primer feed failure is pretty much a thing of the past. I highly recommend this product if you have a Dillon 450 or a Dillon 550. Another little device to add to your reloading machine that makes it run so much better!Verified purchase: YesCondition: New

Do not hesitate , buy that , a REAL improvement for the 550
I usually do not give much credit to the claims of people selling "improvements" to the Dillon 550 reloading press. This one truly is an improvement to the primer feed mechanism. After reading the comments from buyers that have used this article and carefully reading the description I decided that this one just might be a real improvement to the primer feed . I took a chance bought and one . The worn pate was replaced with the new assembly . Careful adjustment is critical ! The press runs noticeable smoother ! Best of all not a single primer feed problem after loading several hundred rounds of .45 ACP ammo with the new set up. I will buy one more for my other 550 press in the future .Verified purchase: YesCondition: New

Reduces down time caused by primer jams.
This is an improvement on the existing mechanism, and it's worth the price. I run two Dillon 550s, one for large primer, the other for small primer. I installed the improved unit on my small primer 550 since that was the one I use for my high volume efforts, and the small primers get jammed more frequently than the large ones. The improvement eliminated most of the jams, and cut my downtime to almost zero. The motion areas have to be kept clean, but primer misalignment has been reduced to an occasional flip, or edge presentation. The smoothness in the travel of the primer bar is apparent immediately. I feel this to have been a good addition to my high volume machine. I have fewer issues with my large primer 550 due to being more deliberate in operating it, and loading much higher capacity cases on that machine. The improvement does need to be adjusted properly, but it's not difficult to get it just right.Verified purchase: YesCondition: New

Top engineered add on
Very well made and has a lot of thought given to the development of this item. The best of all it comes with the best set of directions to give optimum results of installation. Lots of hidden anomalies with the press over time contributed to the reduced operation of the press. The add on brought the press back to better than new life!!!! Thank You for a SUPER product!!! The instructions are worth the price alone! I bought another one for my other Dillon Press which is still working OK - Love It! Thanks Again!! MiltVerified purchase: YesCondition: New
