-After 4 yrs I had of owning this gun a o-ring let loose , only the second one I’ve had to replace . I had it stored for the winter aired up and went to check and charge the digital gauge up like normal every two months or so . I noticed that there was no air. Long story short I had to replaced the o-ring behind the 2nd regulator in the block under the trigger . Purchased a new huma 2nd regulator to put into it . All went well but now the 2nd regulator gauge won’t work . I run two to adjust the regulators easier then seal off the rear when done , well that was the plan , so I got the original and the side mounted digital gauge . Also noticed the plenum is not filling as well . I’ve had the gun apart to detail clean every micro inch and even acquired a endoscopic camera to inspect . I’ve had it apart numerous times and know how it goes together learning from videos on y-tube from the likes of earnest and 911 videos . Never had an issue . I’ve probed and cleaned out the pathways to the gauge , regulators (all parts ) even installed the factory AMP regulator to check if it was the new regulator being a problem . I’ve literally worn out a huma taking it out so many times to check if it was working- I wore out the slot for the screw driver ., I’ve checked the valve rod to ensure it mated in the valve body and was not binding or hanging on the o-rings , cleaned and probed the holes in the air pathway while apart on the plenum and the block …. I’m to wits-end on this one . I’ve miked the valve rod end that screws off to 6.5 (opposite end of gun) and I have adjustment on the part you screw to the lines on the front under the barrel and adjusted the knob's on the side where the numbers are . I can not find a rhyme or reason as I say I’ve had the gun apart numerous times adding hammers and weights plus already installed a new vavle rod back last season . I take care of my equipment like a marine in boot camp . I enjoy working on my equipment when there is info and instructions and usually comes out good but - . I have the front reg set to 170 then went back to 150 to see if that mattered . Can’t figure it out . The 2nd regulator is new or was when I started . The white peek circular piece was installed cupped side facing the brass screw and I got the washer stack from the huma site for the heavy regulator , I know that is correct . The amp regulator was installed watching the 911 video ( to get the stack correct ) plus others to look for a reason ? I’ve also searched here and lerk here from time to time reading articles about the guns own to learn from others .
I hate to give in to send it back for service - anyone have this experience before ?
It also has a new valve body recently but held air since . I had it one time aired up to around 50 bar on the gauge and was increasing but blew out the o-ring in the new Huma regulator aluminum housing (middle o-ring) letting the screw out to adjust to pressure but got that put back finally and thought it was fixed but no luck . This has went on for around 6 weeks waiting for parts for the gun a couple times then parts for my compressor -then this happened . I’m learning to purchase multiple of everything from o-rings to regulator to compressors so when I have time I can shoot - but …. Not even this seems to work out well .
in 4 years of ownership I had to replace the gun housing right after I purchased it because the tiny screw was stuck where the digital gauge goes . Would not budge - so I drilled (learned later this must be heated )- I can tell you that this was not the route to take - but luckily they make plenty of spares at around $500 a whack . Lesson learned - videos of people like Ernest are your friend , too bad I can’t find a video of this problem though … and I’ve tried Not wanting to experience another, let us say unintentional mis- adventure .!
Who ever came up with 73 o-rings is one sick puppy . Seriously demented to put such small o-rings in even smaller holes (3 of them ) but my garage is better for it because I‘ve added numerous tools to work on this thing - ha ha ! After a couple hours of fitting the one in the block and then the huma regulator housing middle o-ring that I had to remove to bottom o-ring to see even with the endoscope and head mounted magnifying glass , I’ve began questioning my sanity and arguing with myself over the best way to do it .
after this I’m thinking of building a stamp sized boat inside a bottle all while I’m juggling chainsaws and listening to cats mating ,eating a ice cream cone in hot august weather . It will be easier !
Please help ?
