Crankshaft and Piston Removal
Removal1. Remove the engine assembly.
2. Remove the transmission:
^ Manual transmission.
^ Automatic transmission.
3. Remove the cylinder head.
4. Remove the oil pan.
5. Remove the engine block end cover.
6. Remove the oil screen (A), then remove the oil pump (B).
7. 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.
8. Remove the bearing cap bridge/bearings. Keep all bearings in order.
9. Turn the crankshaft so No. 2 and No. 3 crankpins are at the top.
10. Remove the rod caps/bearings. Keep all caps/bearings in order.
11. Lift the crankshaft out of the engine, being careful not to damage the journals.
12. Remove the upper bearing halves from the connecting rods, and set them aside with their respective caps.
13. Reinstall the bearing cap bridge and bearings on the engine in the proper order.
14. 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 pistons as they are pushed out.
15. Use the wooden handle of a hammer (A) to drive out the pistons (B).
16. Reinstall the connecting rod bearing and caps after removing each piston/connecting rod assembly.
17. 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 size.
