Coverley - Production Engineer}4/MJ.27.8.37. BENTLEY DEPOT COMPLAINTS. With reference to the number of complaint reports received from Depots on Bentley engines, known as 'Main bearing sinkage', it is anticipated that since the bearing Material has now been changed from AT.418 to AC.2 this change will effect a cure. The improved Material was introduced on the 176th. Chassis in 'K' Series. RHC.{R. H. Coverley - Production Engineer} | ||
