Separating Parts
IMPORTANT: Many internal engine components will
develop specific wear patterns on their
friction surfaces.
When assembling the engine, internal components
MUST be separated, marked or organized in a way to
ensure reinstallation to original location and position.
Mark or identify the following components:
• Piston and the piston pin.
• Piston assembly to the specific cylinder bore.
• Piston rings to the specific piston assembly and
cylinder bore.
• Connecting rod to the crankshaft journal.
• Connecting rod to bearing cap.
• Crankshaft main and connecting rod bearings.
• Camshaft and valve lifters.
• Valve lifters, guides, pushrods, pivot supports and
rocker arms.
• Valve to the valve guide.
• Valve spring and shim.
• Engine block main bearing cap location and
direction.
• Oil pump drive and driven gears.
Tools and Equipment
Special tools are listed and illustrated throughout this
section with a complete listing at the end of the
section.
These tools (or their equivalents) are specially
designed to quickly and safely accomplish the
operations for which they are intended. The use of
these special tools will also minimize possible damage
to engine components. Some precision measuring
tools are required for inspection of certain critical
components. Torque wrenches and a torque angle
meter are necessary for the proper tightening of
various fasteners.
To properly service the engine assembly, the
following items should be readily available:
• Approved eye protection and safety gloves.
• A clean, well-lit work area.
• A suitable parts cleaning tank.
• A compressed air supply.
• Trays or storage containers to keep parts and
fasteners organized.
• An adequate set of hand tools.
• Approved engine repair stand.
• An approved engine lifting device that will
adequately support the weight of the components.
