We should like to know from Mr. Platford whether he has had any cases of gudgeon pin knocks developing when we have fitted the modified type of gudgeon pin in which the screw is used to expand the pin. As soon as we have had a sufficient number of these run any distance, we will put through a standardisation sheet. Hs.{Lord Ernest Hives - Chair} | ||
