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 3516E 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.Note: If the cylinder heads will not be removed from the engine, remove the electronic unit injectors.
