( 1 ) Operating pressure is 65000 2400 kPa (9425 348 psi).
( 2 ) Operating pressure is 111500 3950 kPa (16170 575 psi).
( 3 ) Three hydraulic pumps are listed. Only one pump is necessary in order to carry out the job.Note: Use 8T-0447 Dial Calipers to measure the dimensions in the following procedure.
Keep all parts clean from contaminants.Contaminants may cause rapid wear and shortened component life.
Note: Refer to Disassembly and Assembly, "General Information (Reference Material)" for more information.

Note: The bearing has a locating tab. When the bearing is viewed from the flywheel, counterclockwise rotation is required for the installation of the upper half of the bearing. Ensure that the tab is properly seated in the groove. Ensure that the tab does not break in the groove.Note: If the studs for the main bearing cap were removed, use Tooling (G) in order to clean the threads in the cylinder block prior to the installation of the studs for the main bearing cap. Tighten the studs for the main bearing cap to a torque of 100 20 N m (75 15 lb ft).
Use a clean cloth in order to wipe the upper half of main bearing (11). Apply clean engine oil to the main bearing. Use Tooling (D) in order to roll the upper half of the main bearing into the cylinder block.Note: On the 3608 Engine, the Number 5 main bearing journal does not have an oil hole. Tooling (D) cannot be used in order to roll the upper half of the main bearing in the cylinder block. In order to install the Number 5 main bearing, protect the crankshaft and rap the side of the bearing with the tab with a narrow tool.
