Please note the Experimental Department have agreed to delete the boring up of the camshaft on the above engine. The elimination of the hollow shaft appears to slightly help the position, so far as squeaks are concerned. The Works should immediately stop boring camshafts. This matter is urgent, and the modification should be put through without delay. BY.{R.W. Bailey - Chief Engineer} | ||
