PISTON AND CONNECTING ROD - INSTALLATION
1. 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.
2. Before installing the ring compressor, make sure the oil ring expander ends are butted and the rail gaps located.
3. 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.
CAUTION: Ensure the hole in bearing half aligns with hole in connecting rod, as damage to engine may occur.
4. Position bearing onto connecting rod. Ensure that hole in bearing half is aligned to hole in connecting rod. Lubricate bearing surface with clean
