Ring Indexer Breakage

PreviousPage 2 of 3Next

add: my ring broke as well...

I have 2 dillon 650 presses and they were very very dependable for all the years that I owned them, just normal parts whear that is until this year. I broke a ring indexer on one of my presses about 2 weeks ago and in about a week got the replacement, put the machine back together and about 200 rounds of 223 it blew up. Got another one in the mail yesterday and today that one blew up.

My other press is still doing fine I just hope the indexer on that one never brakes. The replacement parts that they are sending today are at best cheap. I am hoping that I do not have to replace the ring indexer every time I use the press. If that is the case it's good buy dillon.

When replacing this part, the best tool for re-attaching the indexing return spring is a dental tool.

I break one about every 5k cases, so once or twice a week when loading/ prepping brass.

This part is quite a joke. This last week I got two new ones, free for the ones I broke, they were made of a different material. They broke in 2k cycles.

I understand that it designed to break to avoid damage to other components, but it is a non user friendly design.

The same part can be made of billet aluminum, make it 2 pieces with a hinge and hook/camlock detent. This would allow it to snap open when resistance is met to the point of other parts being damaged. But instead of acting like a fuse and requiring entire press disassembly to replace, then realigningn everything, it would be a circuit breaker that you could snap back together to reset.
Would save on shipping parts out under lifetime warranty and making/shipping alignment tools to people. Littler more upfront would save thousands in the long run and customers would be much happier.

Would the longevity of this part be cartridge dependent? I've loaded about 10K .45 ACP with my 650 with no problems whatsoever. But I don't try to do 800 reloads per hour either.

Crap. My ring indexer just broke! I ordered a replacement, but sounds like I might need a few of them. I’ve had my 650 for a few months and loaded a few thousand rounds of various calibers. After reading the previous posts I am a little concerned this going to be a regular occurrence.

I have had a 650 since 1999 and have yet to break a index ring. How hard/fast are you guys manipulating the handle. Slow and consistent are key here. Slamming the handle like a raped ape is what usually causes most issues when reloading.

This thread was a bit surprising to find. At first it made me think I should order an extra indexing ring. But then realized I purchased the 650 in 1998 and have reloaded countless rounds with this machine and I have never experience this type of failure. Regular maintenance and steady paced operation has kept this machine running for the long haul. Now having said that I should probably order the part, just in case?

I have not yet broken an Indexing Ring but I have had them stick and not reset at the top of the press stroke. I am assuming something is dirty and not allowing the index ring to return when I clean it works fine for a while. A more powerful return spring may work but it may break the attachment point on the Ring. It seems to me the best way to fix these problems is to make a index ring out of some type of metal with a stronger return spring. I know I would pay for one.

Had one break today, actually Saturday night. It's going to be well into next week before I see one. No dealers in San Diego. Yes, I know, shocking! 🙂

I get the reason for Dillon using it as the weakest link, but could it be more inconveniently located? ¯_(ツ)_/¯
