Having reverted to bakelite rubbing blocks on the Bentley and we expect shortly on all our chassis, we ought to consider a positive method of lubricating the cam. Our bench experience is that unless the cams are well greased periodically, rapid rubbing block wear occurs and the cam also squeaks. Again we consider that on our chassis we ought not to expect customers to have to grease their cams when a positive method of lubrication is supplied on cheaper cars. A scheme was produced many years ago (LEC.1542) when we originally had bakelite rubbing blocks but was found to be inadequate. A simple felt pad mounted so as to just touch the cam lobes (similar to aero magneto practice) should be quite good. We should be glad to have your views on the matter.
