Engine - Re.Decarbonising. In view of the fact of not having any further piston seizures, I wish to rescind the instructions given in BY.14/G.29.6.38 to remove the block, and add a .100 chamfer on the upper land of the piston. This matter will be reviewed again, in case of further seizures. By.{R.W. Bailey - Chief Engineer} Rm{William Robotham - Chief Engineer} | ||
