Nozzle Measurement

If you can’t find a nozzle specific to your replica, you can determine the correct nozzle by measuring the two distances indicated below and adding them together. Then choose a nozzle from the list that is 0 to 0.5mm longer than your measurement.

Original Engine

With your original engine and nozzle still in the gearbox, measure the distance the nozzle extends from the front of the gearbox.

Wolverine Engine

With your Wolverine Airsoft engine in the gearbox, measure the distance from the front of the engine to the front of the gearbox and add it to your first measurement.

General Engine Maintenance

Regular maintenance on an HPA engine should be performed every 25-50k rounds depending on the conditions it is being used in. The dustier and dirtier the conditions, the more frequently it should be serviced. Maintaining the INFERNO requires disassembling the engine and lubricating/cleaning/replacing the O-Rings.

For detailed instructions, please see the Owner’s Manual for your engine.

For detailed instructions on the solenoid, please see the Solenoid Maintenance Guide.

Troubleshooting INFERNO/Reaper Air Leaks

If your INFERNO Gen 2 is leaking, use this diagram to determine which O-ring may be faulty. For example, if your engine is leaking from around the nozzle, you should check the location and condition of O-ring #4.

For instructions in replacing an O-ring, please see the INFERNO Gen 2 Owner’s Manual.

Cylinder Plugs

The cylinder plugs are part of the manufacturing process and are not adjustable or removable. Never attempt to remove or adjust the cylinder plugs. Doing so will cause leaking and engine malfunction. Already done it? Follow these steps…

  1. Remove the valve from the engine.
  2. Clean the threads of the plug(s) and valve housing thoroughly with acetone or fingernail polish remover and a sharp tool like an O-ring pick.
  3. Apply a small amount of black Vibra-Tite super glue or Loctite to the cylinder plug(s) threads and work it completely around the threads.
  4. Reinstall the cylinder plug(s) flush with the outside of the valve housing. DO NOT screw the plug in all the way as it may damage the valve.
  5. Allow to dry for at least one hour.
  6. Attach an air source and ensure an air-tight seal.
