Service Prior to Assembly

1. Dirt or debris will cause premature wear of the rebuilt engine. Clean all components. Refer to «Cleanliness and Care»(ref-268156-S06496902282007101800000) .
2. Use the proper tools to measure components when inspecting for excessive wear. Components that are not within the manufacturers specifications must be repaired or replaced.
3. When the components are installed into an engine, return the components to their original location, position and direction. Refer to «Separating Parts»(ref-268156-S42784542542007101800000) .
4. During assembly, lubricate all moving parts with clean engine oil. This provides initial lubrication when the engine is first started.

Piston and Connecting Rod Assembly

The pistons are cast aluminum. The pistons use 2 compression rings and 1 oil control ring assembly. The piston is a low friction, lightweight design with a flat or recessed top and barrel shaped skirt. The piston pins are chromium steel and are a full-floating design. The connecting rods are powdered metal. The connecting rods are fractured at the connecting rod journal and then machined for the proper clearance. All applications use a piston with a graphite coated skirt. The piston and pin are to be serviced as an assembly.

Valve Rocker Arm Cover Assemblies

The valve rocker arm covers are cast aluminum and use a pre-molded silicon gasket for sealing. Mounted to each rocker cover are the coil and bracket assemblies. Incorporated into the left cover is the positive crankcase ventilation (PCV) system dirty air passage. Incorporated into the right cover are the oil fill tube and the PCV fresh air passage.

Disassembly and Assembly Procedure Revisions

The timing chain and sprocket installation procedure has been revised. Refer to Timing Chain and Sprockets Installation .
