The snowball effect...
Well, I notice my compressor started clicking on on occasion. It's really odd cause I spent ALOT of time making sure I don't have a single leak. I often good few days or even a week without using it and don't lose any air. Maybe, it goes back to the days when I had a oilless compressor that was sooooo loud it could wake the dead. I made it a point to fix any link so damn thing wouldn't run unless using it.
So as said I started to kick on from time to time. I come to fine out the coupler at end of my manifold was leaking. Ok so I bought a Milton. I recharge the manifold and check. Well found out now my pressure regulator its now leaking. I tried to tighten but screws stripped out out. So now I buy I new one at HD. The way I set this up it's actually easier to take off pump and motor than reseal all the plumbing.
Here's the old ref to new reg.
So I get it all back together and I then snap the the threads in the ball valve. So go to but another valve but couldn't find another like one I got before. This is one on bottom of tank for my drain valve.
So I got a 3/8 ball valve and got 2 3/8 to 1/4 NPT adapters. I installed that one but F@CKING crack one of the adapters. So I put one I had on bottom of tank to shut off and crack on on bottom with crack to the unpressurized size of the drain valve.
Actually, im glad I took to down this far cause I found issue in pressure switch.
While I had it apart I did some modifications to the belt guard.

Before I had to take off the pulleys to get other part of belt guard off. I could never get the pump pulley off. I actually tried and broke off a piece awhile back.
I also show another modification I did before to help changing the oil.
Ok so now I started to put things back together
Ok now from tank I have pop off valve before and after shut off valve. These are both 175 psi valves with compressor being a 155 psi compressor. I fill tank to 60psi and test all that plumbing out. Still a leak. WTF. So long story short the factory install the nut inside regulator upside down. Don't ask me how. Only way I came to this is when I would turn pressure up and after certain psi would drop pressure. So I get finally get that fixed and put all together and test it...... no leaks and holding pressure in tank and from shut off valve to coupler at end of manifold. This is why I love having the shut off there. I can just pressurize the manifold to check for leaks. I can also work of things without draining the tank and refilling it. Just open and close the valve to recharge the manifold.
Now I put all back together. I add pump, motor, do electrical, new modified belt guard pump it up to 150. After all that NOW only thing I didn't messed with ( water separator) now has crack in the bowl. MOTHERF@CKER. Well now I have to go get one of those.
