| Levallois Sr/VAI/ET.25.3.36 To BENTLEY MOTORS Ltd. Derby................ Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer} Re: LEAD BRONZE BEARINGS CHASSIS N°B.179.AE - Mr. F.{Mr Friese} EDMOND-BLANC We note from your Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer}I2/KW.24.2.36, a copy of which we possess, that lead bronze bearings should now not be further fitted to customer's cars. For your information, we possess a set of EB.859, "non drilled up" type connecting rods with lead bronze bearings, recently removed from the above chassis, on which we fitted a set of the "drilled up" type rods with lead bronze bearings, as explained in our memo Sr/VA3/ET.24.3.36. The xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx [Deciphered as: The removed connecting rods were originally fitted with white metal.]. It seems a pity to scrap the lead bronze bearings, which are in very good condition after a service of 31.920 Kms. We would propose, providing that you agree, to fit them at some future date to a car on which the cylinder bores have only a small amount of wear, or on which we have rebored the cylinders and fitted a set of oversize pistons. Of course, we do not wish to experience the same trouble as that recently experienced on chassis B.II8.BL (Spengler), i.e. excessive consumption of oil and, as the rods in question are of the early "non drilled up" type, we do not want to risk piston seizure. We shall be glad to have your views upon the matter. As you are aware, duty has been paid on the above mentioned connecting rods. Sr/VA. | ||
