This precision tool is engineered for the controlled installation and removal of 8mm and 9mm bearings or bushings within airsoft automatic electric gun (AEG) gearboxes. It provides a mechanical method to seat or extract hardware without causing physical distortion or surface damage to the gearbox shell.

Key Features

  • Shell Protection: Minimizes physical stress on the gearbox casing, eliminating the risk of structural warping, hole deformation, or scratching during tech work.
  • 303 Stainless Steel: CNC machined from high-grade 303 stainless steel to provide precise tolerances and high structural durability under load.
  • Dual-Action Functionality: Integrates separate mechanical alignment steps for both press-fitting new hardware and extracting old hardware within a single tool footprint.
  • AEG Standard Specification: Directly compatible with common 8mm and 9mm gearbox bushing and bearing dimensions.

Operation Instructions

  • Installation Method:
    1. Position the small cylindrical head of the tool inside the gearbox shell.
    2. Align the large stepped shoulder so it faces directly against the bearing surface.
    3. Rotate and tighten the retention screw located below the large step to press the component into place.
  • Dismantling Method:
    1. Place the small cylindrical head on the outside of the gearbox shell.
    2. Ensure the alignment steps are facing flush against the bearing.
    3. Tighten the internal screws to pull and extract the component completely from the shell.
