- Using press and adapters, remove pin from piston and rod. Check pin and bores for signs of sticking, excessive wear or damage. Measure pin bore diameter in piston. Standard pin bore is .9048-.9057" (22.982-23.006 mm). Measure outside diameter of pin. Standard pin diameter is .9045-.9047" (22.974-22.980 mm).
- Determine pin-to-piston clearance. Standard clearance is .0003-.0010" (.008-.026 mm). If wear exceeds specification, replace piston and/or pin. Pin must fit into piston with light pressure at room temperature.
- Piston pin is press-fit in rod. Align connecting rod cap mating mark with single valve recess side of piston. Standard interference fit of piston pin-to-rod is .0005-.0015" (.013-.037 mm).
Installation
- Lubricate piston, rings and cylinder bore with engine oil. Install piston rings and properly space ring end gaps on piston. (Scheme 14) Install piston and rod into cylinder bore.
- Ensure "L" (left bank) and "R" (right bank) marks on pistons face timing belt side of engine. Install and tighten rod cap nuts to specification in 2 steps. See TORQUE SPECIFICATIONS.
