I also cleaned everything once I had it all apart.īefore it wouldn't hold enough air to move a pellet and I have no idea what they are supposed to be but with a 14.3g pelletĥ pumps and let it sit for half an hour went 505.6 with a second 5 pump shot right after going 505.0, so I guess old faithful is back in business. Then reassemble the rest like it came apart. This too will take a little pressure (I also used air tool oil). I put the tool in a vise and rotated the tube around while keeping everything in alignment. If you mess up the threads, both are brass and fine thread, you are going to be SOL. With these targets and accessories, you can create a fully functional air gun range for recreation. Find plain targets, targets shaped like game and knockdown targets for filling your shooting range. Even a few early 392/397’s had a soldered valve, and are similar in dis-assembly. Invest in air gun targets and other air gun shooting accessories like scopes, shooting glasses and cleaning kits to help improve accuracy and provide proper gun maintenance.

The spring and hammer are under a little pressure but not too much, in any case remove these parts. Next remove the trigger/safety (don't loose the detent ball for the safety) and rear retaining cap. Then remove the two roll pins that hold the muzzle cap inplace and bring the piston/rod back far enough to line up the pump handle pin with the lower muzzle cap hole and remove that pin. Start by removing the stock screw and stock. After ordering an RWS 34 to play with I came across a rebuild kit from Pyramyd air that cost about $28 including the special tool to take them apart (I was quoted $100 to rebuild it years ago). 22 cal air rifle when I was 11 but it has been dead for years due to worn out parts.
