Cylinder Block

  1. Check cylinder block deck surface for warpage at cylinder head gasket surface. Resurface cylinder block if warpage exceeds specification. See CYLINDER BLOCK  table under ENGINE SPECIFICATIONS. DO NOT remove more than .010" (.25 mm) of material from cylinder block if resurfacing cylinder block.
  2. Measure cylinder bore diameter at top, middle and bottom of cylinder bore parallel with crankshaft and at a 90-degree angle to crankshaft. Ensure cylinder bore diameter, out-of-round and taper are within specification. See CYLINDER BLOCK  table under ENGINE SPECIFICATIONS.
  3. If cylinder bore diameter, out-of-round or taper exceeds specification, hone or bore cylinders on cylinder block for oversize pistons. Pistons are available in .010" (.25 mm), .020" (.51 mm) and .030" (.76 mm) oversize.
    CAUTION: Ensure piston cooling oil jets are removed before honing or boring cylinder bores to prevent damage to cooling jet.
