Used screwdrivers and hoses over the years.I personally found that the clicking sound I was experiencing seemed to be due to overlubrication. I disassembled the pump and wiped down the excess and the clicking noise went away. Bear in mind that this was just my own experience dealing with a single pump however.
My pump also developed a high pitched squeal at one point and that turned out to be caused by a dry bearing on the crankshaft. Those bearing are fairly easily accessed, but they need to be manually lubricated as they receive no grease from the grease pot feed. I used moly grease on those as they are not pressurized or part of the air supply.
One of the tricks I use to try and locate the source of noises is to hold a long screwdriver against various parts of the pump and then to put the end of the handle to my ear. Basicqlly a hillbilly stethoscope.
Hey guy do you think a Cs-4 will work for me to top off the biggest SCBA tank made Scott 5.5 I forget like 90 min or something... I have a aqua environmental external regulator to 6000 psi for my big bore...I've put 7 pistons in my yong heng in 3 years...I realize the cs-4 isn't the biggest fastest unit...I'm comfortable using my yong heng to fill.the big Scott to 300 bar...pretty fast 10 min....Then hook up the cs4 and finish filling. To 5500 psi... I guess buy new from GX official site $509.00 or something... Any input.... Not many options for filling 5500 psi Scott 5.5 tanks....

Your plan sounds like it should work, but for how long, who knows. It's rated for it. If it was me, I would give it a few breaks from 300 to 380 bar.
First of all, 6 X 1/4 turns = 1.5 turns, and that is too much grease according to GX Official.Introducing the exact amount of recommended grease at the recommended interval is blowing off the instructions? But you go ahead and trust a floating baffle that has been extensively written about as being a flaw in the design.

They sell 400 bar burst disk...They advertise 5800 psi? My tanks designed for 5500 psi fills....Regulator fittings and good to 6000 psi... If it won't fill 5500 psi tanks.it shouldn't be advertised as 5800 psi... The new industry standard for scba tanks is 5500 psi...The fireman have been using Scott 5.5 tanks and aqua environmental regulators...The 5.5 tanks are more expensive. Than the 4500 psi ones most people have...Theoretically you COULD, but I wouldn't recommend it, and I certainly wouldn't do it until I talked to Jason if I had my mind set on trying it. 5800 psi / 400 bar is the MAX pressure, not the working pressure. You'd have to replace the burst disc for one thing.
From their CS4 description:
- This CS4 compressor supports the max design pressure 5800psi/400bar, but it does not mean you can fill the max pressure anytime. Almost all pcp tanks and bottles only support 4500psi/300bar as the service pressure to avoid the safety problem, although they state the burst pressure can be over 50mpa/500bar. As a result, the burst disc coming with compressor only support the 350bar as the burst pressure. If you fill over 350bar, it will be blown. If you really need the higher pressure, pls contact with us to buy 400bar burst discs.
Ha! How we used to find the sticky lifter.I personally found that the clicking sound I was experiencing seemed to be due to overlubrication.

It's $15.00 plus shipping for 5 400 bar burst disks from their website. A little pricey but if it works right?They sell 400 bar burst disk...They advertise 5800 psi?

Wow, $36 bucks for 8 oz. That seems a bit steep.I went with something similar, but in a NLGI 0 weight. Over 50 ships free, so I grabbed a few other things.

What kind and or brand of grease are you fellows putting in your grease pot? I've read somewhere it's "food grade" but have no idea why.
And when you get the required hours on your CS4 to turn the grease knob, how do you know you've put in enough? Do you turn the knob while the compressor is running? Under pressure? Or just pumping with the relief valve open? Does the sound of the compressor really change a good bit when you hear the grease going in?
Thx
