Power tube help

It should be in your manual... unscrew your air source adapter under your grip, then remove all receiver screws from the left half of the marker. Now your marker's receiver halves are ready to come apart (leave the cyclone on so that you don't lose that darn sight spring). Remove all internals excluding powertube. Now on the right receiver half (cyclone side) remove those two screws. Note that the new customs come with the required powertube already installed. Check if theres a plastic plug protruding near the safety on the right receiver.

The CVX valve should slide out of the powertube. You will need to get something long and narrow that you can use to push the CVX valve out, but BE CAREFUL WITH THIS. Using a wooden spoon is usually your best bet, but when you start to push it out, do not force it, because you could ruin the internals of the valve. If you have to hammer on the spoon to get your valve out, DON'T. Take it to a pro shop or something and have them do it.

But it should slide out pretty easily.

Once you get it out, you might want to grease it up with some gun lube before you put it back in your new powertube. As long as the holes in the CVX Valve line up with the holes in the powertube when you put it back in, you are good to go.

Anyone else reading this thread may want to double check to make sure you need to replace your power tube. If you have a newer 98, it may already have the newer powertube and be set up to receive the RTand/or Cyclone. You might not have to change it.
