1 Coolant drain plug 2 Torque converter access plug 3 Drive plate 4 Rear cover 5 Main bearing cap 6 Identification mark 7 Front cover 8 Front pulley The main bearing caps are made from cast iron and are cross bolted to increase rigidity. An identification mark on the bearing
cap faces the front of the engine.

At the front of the crankshaft, a tuned torsional vibration damper is incorporated into the crankshaft front pulley. At the rear of
the crankshaft a pressed steel drive plate, with a steel starter ring gear, is installed to transfer drive from the engine to the
transmission. The reluctor ring for the CKP (crankshaft position) sensor is integrated into the perimeter of the drive plate.
The crankshaft seals are located in the front and rear covers.

PISTONS AND CONNECTING RODS



The diameter of each piston is graded and precisely matched to each cylinder bore to help reduce noise. In the vertical plane,
the pistons have a slight barrel form, which helps to ensure a reliable oil film is maintained between the piston and the
cylinder bore. A solid film lubricant coating is applied to both reaction faces of the piston to reduce wear and improve fuel
economy.

A three-ring piston-sealing system is used. The steel top ring is treated with a PVD (physical vapor deposition) peripheral
coating. PVD is a coating technique where material can be deposited with improved properties to ensure good cylinder bore
compatibility and wear resistance. A Napier center ring helps cylinder pressure and oil management, while the three-piece oil
control lower ring is produced from nitrided steel.

The pistons are cooled with engine oil from four piston cooling jets installed under the valley of the cylinder block. Each piston
cooling jet sprays oil onto the underside of the two adjacent pistons, one from each cylinder bank.

The connecting rods are forged from high strength steel. The cap is fracture-split from the rod to ensure precision re-assembly
for bearing shell alignment. There are three grades of large end bearing available, each being color coded. For further
information refer to Engine - 5.0L, Vehicles Without: Supercharger - General Procedures.

Installation

1. CAUTIONS:


Prior to installing the camshafts, position the
crankshaft 45 degrees ATDC cylinder 1A to prevent
valve/piston collision.


Make sure that the camshafts and camshaft bearing
caps are installed in their original locations.


Evenly and progressively install and tighten the
camshaft bearing caps.


NOTE: Lubricate the camshafts and the camshaft
bearing caps with EP90 oil (or 75/90 viscosity oil will
suffice) prior to installation.
Torque: 3 Nm




2. NOTE: Tighten the bolts in the indicated sequence.
Torque: 12 Nm











3. CAUTION: Only rotate the crankshaft clockwise.

Rotate the crankshaft untill the camshaft lobe on the valve being
checked is 180 degrees from the maximum opening position.


4. NOTE: If the valve clearance is incorrect, continue to the next step. If
the valve clearance is correct, continue to step 8.

Using feeler gauge check the gap between the tappet and the camshaft
lobe and check against specifications table.

5. CAUTIONS:


Do not use a magnet to remove the tappet.


Use the following formula to calculate the required bucket
thickness. Original thickness + measured clearance - desired clearance =
required bucket thickness.
Remove the tappet and measure the thickness.
