91. Service Prior to Assembly

Service Prior to Assembly

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