2. Remove the right cover.

5. Loosen the bolts. To avoid warping, loosen the bolts sequentially 1/3 of a turn at a time; repeat the operation until all the bolts are loosened, then remove the bearing cover.
6. Remove the connecting rod bearings and their caps and the main bearings and their caps. Place all caps/bearings in order.
7. Remove the crankshaft from the engine, being careful not to damage the bearings.
8. Remove the upper bearing shells from the connecting rods and set them aside along with the caps.
9. Reinstall the caps and main bearings into the engine in the proper order.
10. If you feel a ring of metal or hard carbon deposits on the top of the cylinders, remove it with a reamer. Follow the reamer manufacturer's instructions. If the ring is not removed, it can damage the pistons when they are pushed out.
11. Push out the pistons with a wooden hammer handle.
12. After removing the connecting rod and piston assemblies, reinstall the connecting rod bearings and their caps.
13. To avoid confusion during reassembly, mark each connecting rod and piston group according to its cylinder number.
Note: The number on the connecting rod does not indicate its location in the engine, but the diameter of the big end of the connecting rod.
