| X7480 Hs{Lord Ernest Hives - Chair}/Rn.{Mr Robinson} from DA.{Bernard Day - Chassis Design} DA{Bernard Day - Chassis Design}1/M20.8.29. X7480 X5300 With reference to Hs{Lord Ernest Hives - Chair}/Rn{Mr Robinson}2/MJ17.8.29. the idea of leaving the clutch trunnion out of the central lubrication was that the thrust bearing was made oil retaining, and would require very little attention. This was shewn on N.Scn.2616 where the standard 20 HP. thrust bearing is modified to be in accordance with SS.{S. Smith} practice. We understand from your note that this has been tried and found not to be successful. Under the circumstances we will shortly send you a nozzle for the 20 HP. similar to that on SS.{S. Smith} DA.{Bernard Day - Chassis Design} | ||
