| contd :- -2- There are a number of ways of doing this but we have shewn a taper pin sticking out on one side, to clear which a groove is provided in one side of the tappet guide. The hole for this pin has to be reamed before hardening the tappet. While on this question of tappet mechanism it might be mentioned that we looked into the question of running the camshaft and tappets completely immersed in a trough of oil as you requested and find it means raising the camshaft about .750".
