- Remove top ridge of cylinder bores with a reliable ridge reamer before removing pistons from cylinder block. Be sure to keep tops of pistons covered during this operation. Pistons and connecting rods must be removed from top of cylinder block. When removing piston and connecting rod assemblies from the engine, rotate crankshaft so that each connecting rod is centered in cylinder bore.
NOTE:
Connecting rod bearing caps are not interchangeable and should be marked before removing to ensure correct reassembly.
CAUTION:
DO NOT use a number stamp or a punch to mark connecting rods. Damage to connecting rod could occur.
- Mark connecting rod and bearing cap positions using a permanent ink marker or scribe tool (Fig 1).
CAUTION:
Care must be taken not to damage the fractured rod and cap joint face surfaces, as engine damage may occur.
