All of these steps are necessary before removing pistons from an engine. Installing rod bolt protector sleeves prevents damage to the crankshaft journals. Removing the cylinder ridge with a ridge reamer prevents the ridge from damaging the pistons as they are removed. Numbering the rods ensures they are reinstalled in the correct order, maintaining the engine's balance and performance.
