Before installing the piston and connecting rod assembly, place the piston rings and be sure the gaps in the compression rings are not straight across from the gaps in the oil rings. Be certain that the end of the connecting rod's oil hole is on the left side of the block which is the thrust side of the cylinder bore, when you are facing the front with the pan rail above. Carefully check that the ends of the oil ring expander match and that the gaps of the rails are set correctly before using the ring compressor. Place the piston head and rings in clean oil and with the special wrench, firmly clamp the ring compressor around the top of the piston, making certain not to move the rings. Misalignment can damage the engine, so place the round hole in the bearing between the holes on the connecting rod; once aligned, oil the round surface of the bearing with clean engine oil. Attach Special Tools 8189 Connecting Rod Guides onto the connecting rod. Arrows and the letter F point to the front of the engine; these markings must be on the pistons of both cylinder banks. The connecting rod oil squirt hole should be pointed toward the major thrust side of the block. Turn the
Crankshaft so the rod journal is right in the middle of the cylinder, then put the rod and piston into the bore as you guide the rod over the journal. Don't put piston assemblies from one bank into another to maintain engine safety. Hammer the piston into place in the cylinder as you also align the connecting rod with its journal. Apply a coating of engine oil to the rod bolts and on the surface under the rod cap, then fit the rod cap and bearing and tighten the bolts to 28 Nm, plus a quarter turn.
