  1. Install the piston rings. (Refer to ENGINE/ENGINE BLOCK/PISTON RINGS - INSTALLATION) 
  2. Before installing piston and connecting rod assemblies into the bore, ensure that compression ring gaps are staggered so that neither is in line with oil ring rail gap.
  3. Before installing the ring compressor, make sure the oil ring expander ends are butted and the rail gaps located as shown in Figure.
  4. Immerse the piston head and rings in clean engine oil, slide the ring compressor over the piston and tighten with the special wrench. Ensure position of rings does not change during this operation.
