How do I choose the correct airsoft bushing size?

Identify the gearbox shell and measure or confirm its required bushing diameter. Use the exact product specification rather than estimating from the gearbox version alone.

What should be checked after installing bushings?

Check that each bushing is fully and evenly seated, then verify gear height, shimming, alignment, and free rotation before completing the gearbox build.
