Dirt will cause premature wear of the rebuilt engine. Clean all components. Use the proper tools to measure components when checking for excessive wear. Components not within the manufacturers specification must be repaired or replaced. When components are reinstalled into an engine, return the components to their original location, position, and direction. During assembly, lubricate all moving parts with clean engine oil or engine assembly lubricant (unless otherwise specified). This will provide initial lubrication when the engine is first started.
