I was sure my GX CS4 needed rebuilt.

I don't like beads at all in my system. I have seen at least one case where the beads deteriorated and particles plugged the fill check valve and got to the valve in a guns. It was kind of a mystery because it looked like rust until the actual cause was discovered.
I worked for many years in the automotive stamping industry. Many of the large press dies were shipped by water from overseas. Desiccant bags were placed in the crates to "absorb" moisture out of the air. I snagged a few of these bags (about the size of cornhole bean bags) and I keep them in my gun safe and cabinets.

It sounds to me these grease pot additions are a joke in itself and more problems than what they're worth....Nothing more than a marketing gimmick?

There are three common types of compressed air dryers: refrigerated compressed air dryers, membrane compressed air dryers and desiccant compressed air dryers.
* Refrigerated dryers-----Are used in heavy use operations where the compressor runs constantly in a shop environment. consist of an air-to-air heat exchanger and an air-to-refrigerant heat exchanger. If the shop temperature is high and or humid, these are the best. Take out a mortgage for these units, very expensive.
* Desiccant dryers----These are great for the release of moister buildup if a drain valve is attached at the bottom. These units are a must to use outdoors on a construction site in cold weather months. In the past, I have had my hoses and nailers freeze up.
* Membrane dryers---- Membrane dryers use highly selective membranes to dry the compressed air. They are able to achieve pressure dew points between +15 and -40 °C and are therefore widely used for a wide range of application. Take out a mortgage for these units, very expensive.
Ambient room temperature is key when filling your units. Nothing will last forever, even if you take out a mortgage to do so.....It's your money!

The rubber gasket has a small rip (not the center tiny hole) and that's what had to have allowed the grease to be pulled into the cylinder.
I'm either going to drill and tap the hole in there for a grease zerk, or just make another gasket out of 1mm rubber.

won't gx send you a new one?

sounds like glass beads .

They most likely are.

As stated earlier, they are NOT desiccant beads of any sort. They are not going to dissolve into your gun. Most likely glass or some other solid material. Remove them and your filter will not work as designed.

It's easier to just make one then wait for a reply.

I don't think the grease pot is a joke so much as poorly designed. It would be better if there was a zerk as they had for a brief time. This way you could actually control how much goes in instead of guessing. Also it seems some suction pulls some into the system.

When used correctly, they work great.
How many posts do we see with people turning the pots from new to "get rid of the air gap".

My brother uses his cs4 a lot, he had it for a year and brought it over to have me look at it.

Not one time was the grease pot turned, yet nearly half the grease was gone. The compressor warms when running and is constantly sucking at that gasket. It will grease itself. At one point GX started telling to not grease it for 50hrs.

Well, his problem was a ripped o-ring on his fill probe. His compressor did the dead head at about 26sec. Beads were clean and drain tube still clear. The grease pot works fine, it's usually operator error...
