order for reassembly.
Refer to
Separating Parts
.
z
At the time of installation, components should be installed in the same location and with the same mating
surface as when removed.
z
An automobile engine is a combination of many machined, honed, polished and lapped surfaces with
tolerances that are measured in millimeters or thousandths of an inch. These surfaces should be covered
or protected to avoid component damage.
z
A liberal coating of clean engine oil should be applied to friction areas during assembly.
z
Proper lubrication will protect and lubricate friction surfaces during initial operation.
SEPARATING PARTS
Separate, mark, or organize the following components:
z
Piston and the piston pin
z
Piston to the specific cylinder bore
z
Piston rings to the piston
z
Connecting rod to the crankshaft journal
z
Connecting rod to the bearing cap
A paint stick or etching/engraving type tool are recommended. Stamping the connecting rod or cap near
the bearing bore may affect component geometry.
z
Crankshaft main and connecting rod bearings
z
Camshaft and valve lifters
z
Valve lifters, lifter guides, pushrods and rocker arm assemblies
z
Valve to the valve guide
z
Valve spring and shim to the cylinder head location
z
Engine block main bearing cap location and direction
z
Oil pump drive and driven gears
IMPORTANT:
z
Disassembly of the piston, press fit design piston pin, and connecting rod
may create scoring or damage to the piston pin and piston pin bore. If the
piston, pin, and connecting rod have been disassembled, replace the
components as an assembly.
z
Many internal engine components will develop specific wear patterns on
their friction surfaces.
z
When disassembling the engine, internal components MUST be
separated, marked, or organized in a way to ensure installation to their
original location and position.
