The bore center distances must be maintained within ±.0005 for sleeve installation to seal properly. (see block specification sheets for dimensions)(See #12 for bore center specs.) 2. All machining must produce a good surface finish and the tolerances must be maintained to assure a quality fit and sleeve seal. 3. Block must be square and perpendicular to machine head. Fixturing should be on main jour- nals provided they are not cracked or distorted. Out of Line 1 and 5, main journals will require main line boring prior to block/sleeve machine work
