Piston Installation

Installation
Before installing the piston, apply a coat of engine oil to the ring grooves and cylinder bores.
1. Install the ring compressor, check that the bearing is securely in place; then position the piston in the cylinder and tap it in using the wooden handle of a hammer.





2. Install the piston/connecting rod assemblies in the cylinder block.
- Guide the piston carefully to prevent damage.
- Fit long rubber hoses [about 30 cm (12 inch) long) to the connecting rod bolts to protect the crankshaft.
- Install the pistons after setting the crankshaft to BDC for each cylinder.
3. Stop after the ring compressor pops free, and check the connecting rod-to-crank journal alignment before pushing the piston into place.





4. Install the rod caps with bearings, and torque the nuts to 44 Nm (4.5 kgf-m, 33 ft. lbs.).





NOTE: Maintain downward force on the ring compressor to prevent the rings from expanding before entering the cylinder bore.
