INSPECTION-ACCEPTANCE AND REJECTION CRITERIA 1. Inspect seal ring grooves in cylinder bores for evidence of pitting and erosion. NOTE Use standard size cylinder liner if diameter (A) is less than 4.5235 in. (114.897 mm), diameter (B) is less than 4.4900 in. (114.046 mm), and diameters (C) and (D) are less than 4.3595 in. (110.731 mm). See Table 1 for cylinder bore diameters requiring oversize cylinder liners. 2. When oversize liner is used, stamp amount of oversize on top of cylinder bore adjacent to liner counter bore using metal stamping die set. Table 1. Oversize Cylinder Liner Size Requirements.
