This is a case of "Once you've done it it is really easy". To get to the links that you wan't to lubricate you need to drop the ram out of the press. Easier than it sounds but if you have not done it it takes a little doing.
First, if you decide not to let Dillon do it for $47.50 including return shipping then commit your self to a couple of hours of time you will not get back. Do yourself a favor and take the priming system, spent primer cup, operating rod etc. off. Likewise pull your toolhead out and set it aside. Take the shell plate and baseplate off (including detent ball) and set to one side. Second unbolt the press from your strong mount or bench and lay the puppy on its side. On the very bottom of ram is a link pin which connects the two arms and on the bottom of this is a "set screw" similar in size and purpose to the one you use when you change shell plates up on top. Remove that set screw and set it aside. Now you are ready to drive the bottom pin out (easy once the set screw is out) and remove the ram.
You are now ready to call Dillon help line and tell them where you are in the process - and they can and will talk you thru everything- including any kinks along the way. I stripped and lubed two older presses just last month when it was so cold and Dillon helped me every step of the way. You will need a couple of punches or a 16 penny nail with the point filed off and Dillon will tell you what to look for on the pins. They even helped me to a couple of creative solutions getting the pins back in. Oh! you will need some grease, like a small tub of axle or bearing grease at Lowe's or Home Depot.
