My 550B is hard to operate. The shell plate, primer feed and powder slide all work just fine. It's the ram that is very stiff. It has been lubed with 30 wt oil as well as all the oil holes on the pivot points. I just called Dillon but of coarse they are closed for the holiday. Anyone else had this problem?

Take one of the pivoting arms off at a time. Clean and lube, replace. Do to both sides and report back.

How long has it sat since you last used it and where does it abide?

Yes. You'll probably need to disassemble and clean all the linkage for the ram. There are also little holes at each end of the toggle links. I use a needle grease fitting (like the ones used on chain saw bar tips) to inject grease in these holes.
 
Check the set screw under the shell plate on the ram body and make sure it is not protruding. Don't ask how I know this...
 
I like Dillon, but have to ask, if I have a Lee does that mean they will be available anytime I need help? 24/7, 365 days a year! I doubt that, so guess I will stick with a REAL reloading press.....in other words, Dillon!
 
Mine got real stiff at one point, too...it is 24 years old and spends winters in an unheated garage. Old grease on the inside of the ram assembly had turned to shellac. I had to soak it to get it clean. I am a 550B fan and have put a lot of miles on mine.
 
Dillon won me over in the early days by going that extra distance when I really needed it. LEE lost me around that time with all the stupid little parts breakage and time lost by mailing parts back & forth.
 
I had a swing arm gall on my RL550. Mine was the era before they put the lube holes in the swing arms. Next time I have mine apart, I am going to drill and tap them for a grease zerk.

If you call Dillon they will send you for no charge a locator pin that is used to align the shellplate platform to the main shaft. I got one, but wound up not needing to use it.

It is fairly easy to disassemble and it's a good time to clean and lube everything.
 
Well after some disassembly and cleaning we are back up and running strong! Quinn, you were right, the crank pivot pin was the culprit. It was stiff as hell and a PITA to remove. But after cleaning and greasing all pivot pins it's smoother than ever!
This machine is 19 years old and has never given me any problems. I,ve rolled tens of thousands of rounds when it was new. Feeding myself and my 2brother in-laws as long as they would pay for the components. It sits in the basement were its warm and dry, but I'll admit it's been idle for years. I would do just a couple of hundred rounds a year. I caught the bug about 6 months ago when I found a nice 586 I just had to have. Since then I been buying bullets in bulk again. Thanks for the input folks!

Even Dillon is not open that much. Take a joke and get off your high horse.

Well, I own a 550B, but would have no problem with a Lee Classic Turret, it's a fine press. I have friends who own them and are quite content.
 
The 550 I used was fairly old and very well used. I wonder if the issues I had with it were that it was in need of a little love. Maybe I would favor them more if I tried a new one or one that had been shown a little more care over the years. Everything seemed so loose fit and allowed a lot of wobble in the press I used. It was in the Nevada desert in a garage so maybe the dust had taken its toll over the years. I was thinking of maybe buying another LNL AP for not having to swap the priming out (which is really pretty easy but yes I'm that lazy) and maybe I should try a 550 of my own. Or at least a SDB since it would be for .40 SW only.
