I thought about it and decided that I didn’t want to bother it because I don’t completely understand how this reg works and I don’t have a reg tester for the factory regulator in the event that I change the setting.

Yeah that part can be daunting. I hope the issue is resolved but I would be remiss to not warn you that the O-ring on the adjuster is an important service item. As described in reply #18, the O-ring on the adjuster (item 7 on the exploded drawing) is one that tends to degrade rather rapidly in most regulators.

@Ezana4CE ,
Very nice, congratulations on your successful rebuild. My favorite kinds of posts are the repairs with good photographs. Let us know how she shoots. I've found my Edguns to be very easy to work on and have been impressed with the ease of maintenance.

To lubricate the Belleville washers, I put just a dab of silicone lube (I used the synthetic super lube) on my fingertips and rubbed them together, then just rubbed a light film on the washers before assembly. As for your other question, item 7 in the drawing above (called 'noozle') is the actual regulator pressure adjusting nut and must be removed to service the o-ring that is on it, thus disturbing the regulator setting. Item 8 is a lock nut to secure its setting in place. I did not remove item 7 and service the o-ring when I did my regulator but I did remove item 8 and measure a depth setting to the head of item 7 in case I decided to do it later and wanted to restore it to its exact setting. And yes, there is a tiny raised nozzle on the inside end of the pressure adjusting nut, item 7. This little nozzle is what seats on the polymer insert in the face of the piston assembly (item 1), and is what performs the valving action of the regulation process. You want to be sure that the seating surfaces are smooth and clean of any debris upon reassembly. Easy to do with visual inspection.

Regards,
Feinwerk

Just to reiterate, if you want to service the o-ring on the regulator adjuster, item 7, and you don't want to change the regulator setting, and you don't have a regulator tester, a workaround solution would be to remove lock nut item number 8, use a depth gauge to measure down to the adjustment nut, and record that fir reference before removing it. Upon reassembly, use this measurement and set it back to the same place you should be able to reasonably expect that the regulator setting will be very close to the original before disassembly. I have not verified this but mechanically it seems like a good solution.

@Feinwerk I tried measuring the depth without removing the stopper. When I got two different depth readings, I thought I’d leave it alone until I figured out exactly what to do. I’m curious as to which reg tester works to read adjustemenrlts for this factory EDgun regulator.

My reg rebuild seems to have corrected the problem. This is the first of three shot strings shooting JSB Kings 25.39 grain diabolo pellets. Only the very first shot of the first string was a little hot.

This works for me. I have experienced a slight POI shift. I need to investigate the cause of that. Thanks to all that contributed with useful input. Hopefully I’ll get to take her her out on a hunt a little later this afternoon.

First few groups were off to the right I adjusted the windage about 10 mil and they still weren’t quite hitting the bullseye. I removed the internals of the moderator to check for clipping and saw no evidence of that. After shooting a few mags I returned the windage turret to where it was and has been for quite some time. The lower right target was the final group shot off of sticks.

I did recently clean the barrel. I guess I had to put a little more lead through it.
