Piston and Connecting Rod - Installation

INSTALLATION





1. Before installing piston and connecting rod assemblies into the bore, install the piston rings.
2. Immerse the piston head and rings in clean engine oil. Position a ring compressor (3) over the piston and rings. Tighten ring compressor (3). Ensure position of rings did not change during this operation.
3. Position bearing onto connecting rod. Ensure that lubrication hole in bearing shell aligns with lubrication hole in the connecting rod. Lubricate bearing surface with clean engine oil.
4. Install Connecting Rod Guides 8507 (4) onto connecting rod bolt threads.





5. The pistons are marked on the piston pin bore surface with a raised "F" (1) indicating installation position. This mark must be pointing toward the front of engine on both cylinder banks. The connecting rod oil slinger slot faces the front of the engine.
6. Wipe cylinder bore clean and lubricate with clean engine oil.
7. Rotate crankshaft until connecting rod journal is on the center of cylinder bore. Insert rod and piston into cylinder bore and carefully position connecting rod guides over crankshaft journal.
8. Tap piston down in cylinder bore using a hammer handle. While at the same time, guiding the connecting rod into position over the rod journal.

CAUTION: The connecting rod bolts must not be reused. Always replace the connecting rod bolts whenever they are loosened or removed.

9. Lubricate NEW rod bolts and bearing surfaces with engine oil. Install connecting rod cap and bearing. Tighten the NEW bolts to 27 Nm (20 ft. lbs.) plus 90°.
10. Install the following components:
- Cylinder head(s) Cylinder Head - Installation
- Timing chain and cover Timing Chain & Sprockets - Installation.
- Cylinder head covers Cylinder Head Cover(s) - Installation - INSTALLATION.)
- Oil pan and gasket/windage tray. Engine Oil Pan - Installation

11. Fill crankcase with proper engine oil to correct level.
