It's a combination so...I did take out the hammer, for those that haven't done it, you are for a treat, also some moments..or longer....of panic. First what I found, my hammer was bone dry and actually a little sticky, so, cleaned it, put a light coat of Mobile One on any and all parts that move, reassembled, tested, no more huge swings, I'm getting about a 3.3 SD over a bunch of shots with different pellets, close enough for right now.
Breech seal, you can feel that with your fingers, air coming out, my personal method to avoid a lot of cursing is to pull the barrel, it'll give you a chance to make sure every thing is tight and easy access to the breech and to clean the barrel at the same time. Lube the probe when done.
Regulators....If you have a digital gauge you can tell really fast if it's the #2 Reg or it's leaking down.
Go to FX and get the schematic for the Maverick.
Now for the hammer removal, Ernst Roe has a nice video on YouTube
Starts at 2;50.
Now today's hints, work in a clean flat area with a nice large white towel....that's to catch the things that will try to escape.
Remove the stock
Remove the Power Adjuster Wheel, there is a little ball bearing there so....go slow, I always grease the little suckers when reassembling, keep them in place, it doesn't matter which number you put it on when reassembling as long as the ball bearing is in the little hole with the little spring.
Remove the little screws holding in the pins on the trigger Assy. Using a small allen wrench, push out the pin closest to the breech from the opposite side of the set screw...WARNING, there is a spring under tension so....HANG ON TO THE PART, PUSH IT DOWN AND WHEN YOU REMOVE THE ALLEN WRENCH SLOWLY RELEASE IT.
Remove the middle pin, it's the limit for the trigger sear
Remove the last pin, closest to the stock, that's the sear, NOTE how it's in or refer to the drawing you've downloaded. The hammer will now fall out.
Check the hammer for any nasties, if it's gouged someone made a huge mistake, deburr it up with fine sand paper.
Clean out the hole, oil the hammer and put it back in, it MUST be kept fully in so keep it slightly tilted down.
Assemble the sear, good luck, I use a allen wrench to get it in place then push in the pin and use the screw, be sure to orientate the sear properly or you'll spend hours figuring it out...been there done that. I'm kinda slow.
Put in the keeper pin in the (Middle) next hole, sear goes under the pin.
Now the fun part, put the spring that tried to escape on the stock end of the sear, and on the SECOND screw from the end of the bar, with the sear groove facing the stock....push it down and locate it with a allen wrench in the hole closest to the breech, push in the pin from the opposite side and secure with the set screw.
Hopefully along the way you've been lightly lubing the moving parts.
Reassemble the Hammer Spring adjuster I always measure the over all distance so I can repeat it if necessary, fyi, one turn of the screw is 1mm which means butt kiss unless you know your starting position. With the greased ball bearing, they really do try to escape, in it's hole with the little spring, put the power wheel screw in THEN lower the power wheel to capture that darn ball bearing, tighten the screw, Oh I hope you greased or oiled the 10 ramps on the adjustor wheel.
Reassemble the stock the long screw goes on the front short on the rear, repreassurize. Oh I'd add a touch of lube to the bottle threads, NO ^%$# silicon, you'll destroy the threads over time.
You can dry fire prior to final assemble but you should be good to go, I'd check it as soon as you get the trigger assembly in. Charge it up and see if things have improved.
NOTE my Maverick .22 Compact started life as a .25 Sniper, I never changed the hammer, that I know of, to the proper weight, I forgot to check it this time...and I'm not so concerned that I'm going to tear it apart to find out.
Charge and test.
