FIGURE 3-159. Measuring Camshaft Bore Diameter
Measure cylinder block top deck flatness using precision straightedge, refer to FIGURE 3-160. New
flatness is 0.003 inch (0.08 mm). If flatness is not as specified, resurface engine block.
FIGURE 3-160. Measuring Cylinder Block Top Deck Flatness
When cylinder block is machined (top deck or crankshaft bearing bores), the dimension from
centerline of crankshaft bearing bore to top deck will be changed. Make sure that this dimension will
not be less than 11.889 inches (301.98 mm). Otherwise, piston may contact cylinder head.
If cylinder block top deck is resurfaced, also measure depth of liner counter bores. Bore depth must
be within 0.234 to 0.236 inch (5.95 to 5.99 mm).
