E.{Mr Elliott - Chief Engineer} Hs.{Lord Ernest Hives - Chair} Hdy.{William Hardy} RHG. Brake Equaliser Shaft - Spherical Seated Bearings. Referring to OWH's complaint that oil drips from the new spherical seated bearings and falls on the silencer, this can only happen on the 20/25. On the Bentley the bearings are not over the exhaust system, and on the Phantom there is a heat shield which catches any oil. Since oil also drops from the existing non-spherical seated bearings, it seems desirable to provide a small shield in the case of the 20/25 and on N. Sch.4185 we have shewn this suggestion. With reference to the additional complaint that more oil is lost from the spherical seated bearings than from the plain type, the spherical bush should of course be a good fit in the bracket. Apart from this, there is a possibility that the liner in the bracket may partly restrict the oil passage to the inside of the bush, and we have also shewn on N. Sch.4185 a suggestion for assuring that the passages are always clear. This suggestion is applicable to all cars. Da.{Bernard Day - Chassis Design} | ||
