( 1 ) Either pump may be used for this procedure.
Keep all parts clean from contaminants.Contaminants may cause rapid wear and shortened component life.
Note: This procedure assumes that the Disassembly and Assembly, "Crankshaft Main Bearings - Remove" procedure was followed. At the beginning of this procedure, the main bearing cap is supported by Tooling (B). For more information on the use of the Tooling, see Tool Operating Manual, NEHS0762.
Lubricate the inside diameter of the upper half of the main bearing with clean engine oil.
The upper half of the main bearing has a tab. If the tab is pushed against the crankshaft, the cylinder block, the bearing, and the crankshaft can be damaged.When you remove the upper half of the bearing, always rotate the crankshaft so that the tab is the first part of the bearing to be removed.When you install the upper half of the bearing, always rotate the crankshaft so that the tab is the last part of the bearing to be installed.
The main bearing driver can be broken if the long end of the blade is used to install the bearing. Always use the short end of the blade to install the bearing.

Install Tooling (G) into the oil hole of the main bearing journal. Make sure that the short end of the blade will press against the crankshaft main bearing when the crankshaft is rotated. Start the installation of the upper half of crankshaft main bearing (15) by hand. Rotate the crankshaft so that the end of the crankshaft main bearing with the tab will be installed last.

Note: Use a pry bar that is padded to support the end of the crankshaft main bearing, if necessary.
A gap may develop between the lower part of the crankshaft main bearing and the main bearing journal. This can cause the crankshaft main bearing to bind. If a gap develops, use a pry bar that is padded with a towel to provide upward support to the crankshaft main bearing. Be careful not to deform the crankshaft main bearing.Rotate the crankshaft main bearing onto the main bearing journal until the end of the crankshaft main bearing with the tab is even with the edge of the bore.
After the upper half of the crankshaft main bearing is installed, reverse the direction of the crankshaft in order to remove Tooling (G) from the main bearing journal.

Because of high pressure, a tight bending radius or a kink in a hose could cause the hose to break and result in personal injury.Do not allow the hoses to bend in a radius that is less than 250 mm (10 inch).Before you use a hose, always inspect the hose. Never use a hose that is damaged, defective, or kinked.
