Engineer} 202 Rm{William Robotham - Chief Engineer}/FJH.{Fred J. Hardy - Chief Dev. Engineer}1.11.37. BENTLEY AXLE PINION BEARINGS. Will you please note that when fitting pinion bearings having 0.005 preload, the nip washer GB.2704 which is normally made 0.002 greater than the free gap between the cover GB.584 and the bearing, should be made 0.006 greater to allow for the compression of the bearing when tightened down.
