| -2- RM.{William Robotham - Chief Engineer}1/AP.4.6.37 With this increase in bearing area, and the introduction of the overdrive, we expect that we shall be able to revert to babbitt main bearings on all cars and that trouble is likely to be a thing of the past. Nevertheless, if ever we supercharge, or find a means of shortening the engine without reducing the power output, the experience we have gained with high duty bearings will be invaluable.
