Bailey - Chief Engineer} 206 Rm{William Robotham - Chief Engineer}/AFM.{Anthony F. Martindale}22/AP.6.4.37 BENTLEY INERTIA BALANCER N.SCH.4865 This balance lever has an oilite bush which does not wear very well. Most of the experimental cars have developed slack. GwH.{George W. Hancock - Head Chateauroux} is complaining about it on customers cars. We are going to try a dry Manganese Bronze bush, but if this does not work we may have to change to a lubricated brass bush. If too much slack develops the device ceases to function, and rattles. Rm{William Robotham - Chief Engineer}/AFM.{Anthony F. Martindale} | ||
