Crankshaft and Pistons
Crankshaft and Pistons Removal1. Remove the timing chain.
2. Remove the bearing cap bolts. To prevent warpage, unscrew the bolts in sequence 1/3 turn at a time; repeat the sequence until all bolts are loosened.
3. Remove the main bearing cap. Keep all bearings in order.
4. Remove the rod caps/bearings. Keep all caps/ bearings in order.
5. Lift the crankshaft out of the engine, being careful not to damage the journals.
6. If you can feel a ridge of metal or hard carbon around the top of each cylinder, remove it with a ridge reamer (A). Follow the reamer manufacturer's instructions. If the ridge is not removed, it may damage the piston as it is pushed out.
7. Use the wooden handle of a hammer (A) to drive out the piston (B).
8. Reinstall the connecting rod bearings and caps after removing each piston/connecting rod assembly.
9. To avoid mix up on reassembly, mark each piston/ connecting rod assembly with its cylinder number.
NOTE: The existing number on the connecting rod does not indicate its position in the engine, it indicates the rod bore size.
