Shooting / Air System / Leak Problem Troubleshooting [X7 Phenom]
To troubleshoot an X7 Phenom air leak, first determine the location of the leak.
If the leak is from the Tank / Tank Adapter ASA:
- This leak comes from a cut or nicked 18-PA Tank Valve Oring. These Orings screw in and out over threads every time you install and remove your air tank. It is the most common cause of a leak, and the Oring replaced most often. Be sure to always have extra.
- Check / replace the TA30049 Gas Line Oring
- Check the TA30045 Gas Line Assembly for cracks or nicks
- Check the TA30015 Tank Adapter ASA for cracks or nicks
If the leak is from the Lower Receiver Grip Assembly / Upper Receiver Assembly:
- Check / replace the TA30049 Gas Line Oring
- Check the TA30045 Gas Line Assembly for cracks or nicks
- Check / Replace the TA20008 Trigger Pin Oring
- Check / Replace the TA30039 Trigger Pin
- Check / Replace the TA30050 Valve Spool Spacer Oring
- Check / Replace the TA30020 Valve Spool Spacer
If the leak is from the Breech / Front Bolt:
- Check / Replace the TA30049 Firing Spool Oring Small
- Check / Replace the TA30053 Firing Spool Oring Large
- Check / Replace the TA30038 Firing Spool Assembly
If the leak is from the TA10038 End Cap / TA30022 Regulator Velocity Adjuster:
- Check your Chronograph Speed / Pressure, and input pressure and adjust as needed. To adjust the marker’s velocity, use a ⅛ inch Allen wrench in the holes of the velocity adjuster. The velocity adjuster is located on the right side of the Upper Receiver. The Piston Assembly has a built in Pressure Relief Valve. This assembly is factory preset, and should not be adjusted or disassembled. It will vent in the case of over pressurization to prevent damage and failure of other components.
- Check / Replace the TA30052 Regulator Piston Oring
- Check / Replace the TA20075 Regulator Pin Seat
- Check / Replace the TA30028 Regulator Pin
- Check / Replace the TA30104 Regulator Piston Assembly. This assembly is factory preset, and should not be adjusted or disassembled.
