1. Record the main bearing code found on the front of the engine block.





2. Record the main bearing code found on the crankshaft counterweight.





3. Using the data recorded earlier and the Bearing Select Fit Chart, Standard Bearings, determine the required bearing grade for each main bearing.
- Read the first letter of the engine block main bearing code and the first letter of the crankshaft main bearing code.
- Read down the column below the engine block main bearing code letter, and across the row next to the crankshaft main bearing code letter, until the 2 intersect. This is the required bearing grade for the number one crankshaft main bearing.
- As an example, if the engine block code letter is "F" and the crankshaft code letter is "D", the correct bearing grade for this main bearing is a "2".
- Repeat this process for the remaining four main bearings.





4. If oversize bearings are being used, use the procedure in the previous step and the Bearing Select Fit Chart, Oversize Bearings to determine the required bearing grade for each main bearing.

5. NOTE: Before assembling the cylinder block, all sealing surfaces must be free of chips, dirt, paint and foreign material. Also, make sure the coolant and oil passages are clear.

Install the crankshaft upper main bearings into the cylinder block and lubricate them with clean engine oil.





6. NOTE: The upper thrust washers are shown for location purposes only. Do not install the upper thrust washers until the crankshaft is installed. refer to the following 2 steps. Install the crankshaft onto the upper crankshaft main bearings.





7. NOTE: The oil groove on the thrust washer must face toward the front of the engine (against the crankshaft thrust surface).

Push the crankshaft rearward and install the crankshaft upper thrust washer at the back of the No. 5 upper main bearing.





8. NOTE: Rotate the Jack screws into the bearing caps enough to provide clearance to the cylinder block prior to installing the bearing caps.

Install the rear main bearing cap.

9. Install the crankshaft lower main bearings into the main bearing caps and lubricate them with clean engine oil. Locate the main bearing cap on the cylinder block, and keeping the cap as square as possible, alternately draw the cap down evenly using the cap fasteners.





10. Tighten the vertical main bearing cap fasteners in the sequence shown, in 2 stages:
- Stage 1: Tighten to 40 Nm (30 ft. lbs.).
- Stage 2: Tighten an additional 90 degrees.





11. Tighten the Jack screws against the cylinder block in the sequence shown.
- Tighten to 5 Nm (44 inch lbs.).
- Tighten to 10 Nm (89 inch lbs.).





12. Install the side bolts and tighten them in the sequence shown.
- Tighten to 21 Nm (15 ft. lbs.).

13. Assemble the 8 pistons.





14. CAUTION: Do not scratch the cylinder walls or crankshaft journals with the connecting rod.

NOTE: The next three steps are for all eight connecting rods, rod caps and pistons. Only one connecting rod, rod cap and piston is shown.

NOTE: Make sure the identification marks on the piston and connecting rod face toward the front of the engine.

Use the special tools to install the piston and connecting rod with the upper connecting rod bearing in place.





15. CAUTION: Do not scratch the cylinder walls or crankshaft journals with the connecting rod.

Once the connecting rod is seated on the crankshaft journal, remove the Connecting Rod Installer.

16. CAUTION: The rod cap installation must keep the same orientation as marked during disassembly.

NOTE: The connecting rod caps are of the "cracked" design and must mate with the connecting rod ends. Excessive bearing clearance will result if not mated correctly.

Position the lower bearing and connecting rod, and install the new bolts loosely.





17. NOTE: Main bearing caps are removed for clarity.

Tighten the bolts in 2 stages, using the sequence shown.
- Stage 1: Tighten to 43 Nm (32 ft. lbs.).

- Tighten to 10 Nm (89 inch lbs.).





19. Install the pickup tube spacer.
- Tighten to 25 Nm (18 ft. lbs.).





20. CAUTION: Make sure the O-ring is in place and not damaged. A missing or damaged O-ring can cause foam in the lubrication system, low oil pressure and severe engine damage.

NOTE: Clean and inspect the mating surfaces and install a new O-ring. Lubricate with the O-ring with clean engine oil.

Position the oil pump screen and pick-up tube and install the bolts.
1. Tighten to 25 Nm (18 ft. lbs.).
2. Tighten to 10 Nm (89 inch lbs.).





21. NOTE: Clean and inspect the mating surfaces, and install new gaskets.
Position the oil filter adapter and install the 4 bolts.
- Tighten to 25 Nm (18 ft. lbs.).





22. CAUTION: Make sure all coolant residue and foreign material are cleaned from the block surface and cylinder bore.

CAUTION: The use of sealing aids (aviation cement, copper spray and glue) is not permitted. The gasket must be installed dry.

CAUTION: The cylinder head bolts must be discarded and new bolts installed. They are tighten-to-yield designed and cannot be reused.

NOTE: Do not turn the crankshaft until instructed to do so.

NOTE: LH shown, RH similar.

Using the special tools, position the cylinder head gaskets and cylinder heads over the dowels and install the cylinder head bolts loosely.





23. Tighten the bolts in 3 stages, in the sequence shown. RH shown, LH similar.
- Stage 1: Tighten to 40 Nm (30 ft. lbs.).
- Stage 2: Tighten an additional 90 degrees.
- Stage 3: Tighten an additional 90 degrees.





24. Install the RH exhaust manifold gasket and the exhaust manifold. Tighten the nuts in the sequence shown.
- Tighten to 25 Nm (18 ft. lbs.).





25. CAUTION: Clean the engine support insulator-to-cylinder block mating surfaces of any dirt or foreign material prior to installation.

Position the RH engine support insulator and install the bolts.

27. CAUTION: Timing chain procedures must be followed exactly or damage to valves and pistons will result.

CAUTION: Prior to installation, inspect the tensioner-sealing bead for seal integrity. If cracks, tears, separation from the tensioner body or permanent compression of the seal bead is observed, install a new tensioner.

Compress the tensioner plunger, using a vise.





28. Install a retaining clip on the tensioner to hold the plunger in during installation.
29. Remove the tensioner from the vise.

43. Remove the retaining clip from the RH timing chain tensioner.





44. Make sure that the copper (marked) chain links are lined up with the dots on the crankshaft sprockets and the camshaft sprocket.





45. Install the crankshaft sensor ring on the crankshaft.





46. NOTE: Camshaft roller follower is shown removed for clarity.

Install the special tool between the valve spring coils to prevent valve stem seal damage.





47. NOTE: The camshaft roller followers must be reinstalled in their original locations.

NOTE: Position the cam lobe away from the valve stem prior to installing each camshaft roller follower.

Use the special tool to compress the valve springs, and install the camshaft roller follower.

48. NOTE: The camshaft roller followers must be installed in their original locations.

Repeat the previous 3 steps for each camshaft roller follower.





49. CAUTION: Do not use metal scrapers, wire brushes, power abrasive discs or other abrasive means to clean the sealing surfaces. These tools cause scratches and gouges which make leak paths. Use a plastic scraping tool to remove all traces of old sealant.

NOTE: If the engine front cover is not secured within 4 minutes, the sealant must be removed and the sealing area cleaned. To clean the sealing area, use silicone gasket remover and metal surface prep. Follow the directions on the packaging. Failure to follow this procedure can cause future oil leakage.

NOTE: Make sure that the engine front cover gasket is in place on the engine front cover before installation.

Apply a bead of silicone gasket and sealant along the cylinder head-to-cylinder block surface and the oil pan-to-cylinder block surface, at the locations shown.
