Manual Transmission

4.9 Bearings. In a manual transmission, the gears and shafts are supported on bearings or bearing surfaces. This allows for rotation and also maintains the alignment of the components. The type of bearing used at each loing point depends on the load which must be sustained. Radial loads try to force the gears and shafts apart.
