The cylinder liners and the camshaft

Mr. Wilson - Why do you want to replace only 3 cylinder liners I wonder?

Ch.Eng - You see these liners are badly damaged through erosion on the cooling water side and have some ellipsoidal wear. That's why they are to be replaced. As to the other liners they require checking. Then we'll see what should be done.

Mr. Wilson - We must know the exact number of cylinder liners to be renewed because the delivery takes rather much time. So we'll speed up the dismantling of the cylinder liners and carry out the necessary survey of defects as quick as possible.

Ch.Eng. - We'd like to have your opinion about the other three liners in two days. Can you manage it?

Mr. Wilson - You see, it's necessary to grind the camshaft journals, other wise it's impossible to replace the bearings. The camshaft labyrinth packing should be renewed too, I think.
