Inspection and Reconditioning
NOTE: Refer to the Specifications Section for specific
dimensions that are not given in this section.
This section covers the cleaning, inspection, overhaul, and
assembly of individual engine components. After disassem-
bling the engine, check the components and discard unus-
able parts such as gaskets, O-rings, burned valves, and
broken rings. Check the items that may need machine shop
work first so this work can be completed by the time the rest
of the engine is ready to assemble.
Cylinder Block
1. Inspect the cylinder block for cracks, damage, and dis-
tortion. Use a straight edge and a feeler gauge to check
the cylinder block deck for distortion. Check all four
sides, both diagonals, and the center lines of the cylin-
der block deck. If there is more than .002 in. (0.05 mm)
distortion, resurface the cylinder block. Do not remove
more than .002 in. (0.05 mm) from the surface of the
cylinder block.
