CYLINDER BLOCK REPAIR - CONTINUED
Inspect all parts. Replace if cracked, broken, distorted or threads or bore damaged.
Use adequate light source to visually inspect cylinder block inside and out. Discard if cracks are observed at crankshaft
bearing bores or camshaft bearing bores (B), at main bearing cap mounts or at any location on external surfaces.
Use magnaflux (preferred) to dye penetrate or magnetic particle equipment to inspect cylinder block. Follow manufac-
turer's instructions. Discard cylinder block if cracks are detected at bearing bores (B and C), cap mounts or external sur-
With main bearing caps in place, Use 5-6 in. inside micrometer to measure crankshaft bearing bores (C). Discard cylin-
der block if bores do not measure 5.1138+0.0005 in. (129.8905+0.0127 mm).
Visually inspect top deck (A) area around each cylinder liner (39). Recondition according to steps 22 through 36 if scal-
ing, pitting, corrosion or other evidence of liner seal failure is present.
