1. Before installing piston and connecting rod assemblies into the bore, install the piston rings (Refer to
9 – ENGINE/ENGINE BLOCK/PISTON RINGS – STANDARD PROCEDURE).
2. Immerse the piston head and rings in clean engine oil. Position a ring compressor over the piston and
rings. Tighten ring compressor. Ensure position of rings do not change during this operation.
3. Position bearing onto connecting rod. Lubricate bearing surface with clean engine oil.
4. Install Connecting Rod Guides 8507 into connecting rod bolt threads.
5. The pistons are marked on the piston pin bore surface with an raised “F” or arrow on top of piston
indicating installation position. This mark must be painting toward the front of engine on both cylinder banks.
6. Wipe cylinder bore clean and lubricate with 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, guide connecting rod into
position on rod journal.
9. Wipe connecting rod cap clean and install bearing.
10. Lubricate with clean engine oil and install new rod bolts.
11. Lubricate bearing surfaces with clean engine oil. lighten bolts to 21 N·m (15 ft. Ibs.) plus a 90 0 turn.
12. Cylinder head(s). (Refer to 9 • ENGINE/CYLINDER HEAD – INSTALLATION).
13. Cylinder head covers (Refer to 9 – ENGINE/CYLINDER HEAD/CYLINDER HEAD COVER(S) -INSTALLATION).
14. Install the intake manifold.
15. Oil pan and gasket/windage tray. (Refer to 9 – ENGINE/LUBRICATION/OIL PAN – INSTALLATION).
16. Fin crankcase with proper engine oil to correct level.
17. Connect negative cable to battery.
