Remove the rocker shaft assemblies and pushrods.
Remove the front housing.
Remove the balancer gear from the rear gear group.
Remove the flywheel 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 engine has the following weight:
3512F Engines weigh approximately 5902 kg (13,000 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.
