Piston Installation
Piston Installation
If the Crankshaft is Already Installed
1. Set the crankshaft to bottom dead center (BDC) for each cylinder as its piston is installed.
2. Remove the connecting rod caps, then install the ring compressor. Check that the bearing is securely in place.
3. Apply new engine oil to the piston, inside of the ring compressor, and the cylinder bore, then attach the ring compressor to the piston/connecting
rod assembly.
4. Position the piston/ connecting rod assembly with the arrow (A) facing the cam chain side of the engine block.
5. Position the piston/ connecting rod assembly in the cylinder, and tap it in using the wooden handle of a hammer (A). Maintain downward force on
the ring compressor (B) to prevent the rings from expanding before entering the cylinder bore.
6. Stop after the ring compressor pops free, and check the connecting rod-to-rod journal alignment before pushing the piston into place.
7. Check the connecting rod bearing clearance with plastigage See: Connecting Rod Bearing/Service and Repair.
8. Inspect the connecting rod bolts See: Service and Repair/Overhaul/Connecting Rod Bolt Inspection.
9. Apply new engine oil to the bolt threads, then install the rod caps with bearings. Torque the bolts to 29 Nm (3.0 kg-m, 22 lb-ft).
10. Tighten the connecting rod bolts an additional 90 °.
