Cylinder Liner - Cleaning and Inspection for Reuse (1-04) Section 1 - Cylinder Block - Group 01 M11 Page 1-24 Visually inspect the outside diameter of the liner for ex- cessive corrosion or pitting. Liners with pitting generally cannot be reused. However, if the pitting is light and can be removed with fine emery cloth, the liner can be reused. Visually inspect the liner inside diameter for vertical scratches deep enough to be felt with a fingernail. If a fingernail catches in the scratch, the liner must be replaced. Visually inspect the liner inside diameter for scuffing or scoring. Visually inspect the liner inside diameter for liner bore polishing. NOTE:
M11 cylinder liners are not lubrited. A moderate polish (A) produces a mirror finish in the worn area with traces of the original hone marks or an indica- tion of an etch pattern. A heavy polish (B) produces a bright mirror finish in the worn area with no traces of hone marks or an etch pattern. Replace the liner if either of the following conditions ap- ply: A heavy polish is present over 20 percent of the piston ring travel area. 30 percent of the piston ring travel area has both moderate and heavy polish, and one half (15 per- cent) is heavy polish.
