Bergen Intrepid Magnum Tazer, Manual, Page: 33 / 88

Push down on the pinion/cage, tightening the mesh until you have ZERO
backlash AND the system runs smooth. Pushing down on the cage may
require some tamping with an allen driver as the frames are tight against the
cage, but it will move and will tighten up the mesh.
Now tighten the bolt going through the bearing block and cage.
Peer through the boom clamps at the delrin coupler, ensuring it is centered
up and down. Loctite and tighten the 4 3X8 SHCS holding the rear of the
cage to the upper frames
Set the pinion height to the main gear, loosening the upper shaft collar,
pushing up on the shaft/pinion assy while pushing down on the collar.
Loctite and tighten the setscrews. The top of the pinion should be at least as
high as the main gear.
