Dillon 650 Case Insert Slide

[Lefty2506]

Does anyone know of a company that offers a machined Case Insert Slide for a Dillon 650 (same as the 750 I think)? I don't load as much as I used to, but I still wear out the glass filled nylon OEM part every few years, which equates to every few thousand rounds. The cost of the plastic replacement part isn't bad, but I'm really tired of dealing with the headache it causes when it starts to have issues. It always happens as I'm at the tail end of a batch and I end up struggling with it for the last hundred rounds or so. I'd really like to upgrade to something machined from aluminum or printed out of metal depending on the cost.

Thanks,
Mark

For starters I'm really not sure which part you are talking about, but I've had my 650 since it first came out and the case feed system since they first came out. I've loaded well over 500,00 rounds on that loader and have not had to change any parts on the case feed system. Changed and upgraded lots of other things on it, but not the case feed system other than caliber changes. Seems to me like something may not be right on your machine if that part is wearing out that quickly. I'd like a little more information and maybe a picture or two.

See pics below. I bought mine in '97. Over time, the lower lips tend to flare out like a worn out slide on a 1911. Once that happens (at least on mine), it allows the entire assembly to tilt sideways while the ram is going up. At that point, things bind up and everything starts getting a lot worse real fast.

Now that you mention it, I have never seen an aftermarket replacement for this part.

I will also chime in that something sounds wrong with the idea that this part should wear or break that fast. I would have to replace it every few months at your rate. Something extraordinary is going on.

Maybe take a look at the mating surfaces to make sure there isn't a defect there and make sure you are lubricating the interface.

Failing to find the cause, Dillon spare parts kits are available and if that one isn't part of their standard kit, it should be trivial to keep two on hand.

I'll take another look at the area and see if I can see any damage or abnormal wear to the aluminum casting in that area. Remembering back, I don't think I had any issues for the first several years that I was using it, and I was shooting a lot more back then. Most of my issues have been in the last decade or so. I think its one of those things where once I had to replace it, it hasn't been quite right sense.

Out of curiosity, what kind of grease are you guys using? I can't recall what I've been using (label has been gone for a LONG time), but it just looks like translucent yellow grease. I just googled it and noticed that Dillon's youtube video uses a blue grease that I presume is wheel bearing grease. My assumption has always been that the grease type doesn't matter for this application since I'm not running it at thousands of cycles per minute, and I'm not washing it down with a hose.

Without making a research project out of what would be "the best" grease for that slide, I would just make sure the thing stays "wet" with grease and check it every session or 1000 rounds whichever comes first. If Dillon sells you a maintenance kit, why not try that first?

At some point I was called a tribologist (friction and wear scientist) and would say just about anything that keeps that interface wet with grease, is going to prevent damage from running it dry.

Most of the times with polymer against aluminum alloy, anything called a grease puts the friction coefficient in the 0.1 class or a little better. If the grease has additives like PTFE, or MoS2, all the better and you might see a 0.07, but we would be splitting hairs. The real trouble comes if you starve the interface and the coefficients get up above 0.2 or worse.

If you have a good quality synthetic gun grease, or a good quality synthetic chassis grease, I would run that before I would let it go dry.

If it’s worn out contact Dillon they will replace it.
I went in to buy a new small powder bar spacer because I misplaced it (totally my fault). Guy at the counter handed me a replacement.
Outstanding customer service and they have lifetime warranty impresses up to 750

That's not the part I'm talking about. I'm talking about the part that this would attach to.

Got it. I’ve cycled my press well over 100,000 times over the past 5 years and that part has not worn out for me. I do happen to have an upgraded bearing camming pin:

I have had a chance to get back to it (part of a tree fell on the garage), but I'm guessing that I have something else worn that is causing my problem. I'll tear it apart and see what's going on and then get the appropriate replacement parts. That said, I do LIKE that upgrade! I'd definitely be willing to drop $20 on it.
