| -2- Hm{Capt. W. Hallam - Head Repairs}4/W25.10.26 Contd. Experimental Dept. data in which full technical information is given on oil leakage in Engine Bearings. This experimental data is of the most important value and has apparently been neglected. We find that the most reliable way of testing the clearance in an Engine Bearing is to insert a piece of soft lead fuse wire in the Bearing, tighten it up and measure the thickness the wire has been compressed to. If properly selected wire is used it does no damage to the Bearing. Hm.{Capt. W. Hallam - Head Repairs} | ||
