Service prior to Assembly
• Dirt or debris will cause premature wear of the rebuilt
engine. Clean all components. Refer to Cleanliness
and Care.
• Use the proper tools to measure components when
checking for excessive wear. Components that are
not within the manufacturers specifications must be
repaired or replaced.
• When components are reinstalled into an engine,
return the components to their original location,
position and direction. Refer to Separating Parts.
• 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. Refer to
Sealers, Adhesives and Lubricants.
