Remove the rocker shaft assemblies and the pushrods.
Remove the flywheel housing.
Remove the front housing.
Remove the piston cooling jets.
Failure to remove the rocker shaft assemblies and push rods can result in damaged valves when the pistons and connecting rods are pushed away from the crankshaft.To help avoid damage to the valves, remove the rocker shaft assemblies and push rods before you remove the crankshaft.
Keep all parts clean from contaminants.Contaminants may cause rapid wear and shortened component life.
Use Tooling (A) to turn the engine to a horizontal position. The engine can be supported with Tooling (A) or with blocks.
The weight of the 3508C Engine is approximately 4535 kg (10000 lb).
The weight of the 3512C Engine is approximately 6800 kg (15000 lb).
The weight of the 3516C Engine is approximately 9100 kg (20000 lb).Note: It is not necessary to remove the counterweights from the crankshaft, if the piston and connecting rod assemblies have been removed from the engine.

Attach Tooling (B) to each end of crankshaft (7). Attach a suitable lifting device to Tooling (B). The weight of the 3508C crankshaft is approximately 400 kg (880 lb). The weight of the 3512C crankshaft is approximately 600 kg (1325 lb). The weight of the 3516C crankshaft is approximately 800 kg (1765 lb).
Remove bolts (5) and main bearing caps (6).
Remove thrust plates (8) from each side of the center main bearing.
Remove crankshaft (7) from the cylinder block.

If necessary, remove bolts (9) and crankshaft gear (10) from each end of the crankshaft. Installation Procedure
Illustration 5 g01124614
Install plugs (11) and tighten to a torque of 50 7 N m (37 5 lb ft).
Position crankshaft gear (10) on the crankshaft and install bolts (9).
Illustration 6 g01124115Note: Install the main bearings dry when clearance checks are performed. Refer to Disassembly and Assembly, "Bearing Clearance - Check". Apply clean engine oil on the main bearings for final assembly.
Install the upper half of main bearing (12) in the cylinder block. Ensure that the main bearing is installed so that the bearing tab fits into the notch in the cylinder block. Coat the main bearing with clean engine oil. Note: The upper half of the main bearing has an oil hole in the center.
Install the upper halves of connecting rod bearings (13) in the connecting rod assemblies. Coat the connecting rod bearing with clean engine oil.
