Found this on pb nation.
1. Pull the pin out from the back where you screw the tank in. Note which side faces front, dont reverse it when reinstalling. 2. Remove the set screw on the top. 3. Push the twist lock out from where you removed the set screw. DO NOT LOOSE THE BALL! 4. Needle nose plyers to pull out the brass peice from inside. Relube both orings on the brass peice. One inside and the outter ring. The little peice needs to be relubed as well. 5. Put the brass peices back in first. Smaller diameter peice faces front of cam drive, little oring faces front. 6. Slide the twist lock back in, placing the ball in the hole with the spring. 7. Tighten the screw back in to hold the twist lock. I tightened all the way, then backed it out just a tiny bit to allow a little easier movement. 8. Place pin back in. *NOTE* Only the brass peices have the orings that need to be lubed. Removing the twist lock doesn't really matter, but I did so anyway. I noticed an exssesive amount of lube throughout the cam drive and mine was leaking. I wanted to fully dissmantle it and relube it myself. I also just love knowing how things work lol..
