The correct location of valve bridges on valve stems is shown.
Engines that have valve bridge clips (9) originally installed on valve bridges (5). Remove the valve bridge clips from the valve bridges.
Clean valve bridges (5). Inspect the valve bridges for wear and damage. Replace any valve bridges that are worn or damaged.
Install Tooling (F) onto valve bridges (5).
Lubricate valve bridges (5) with clean engine oil.
Failure to ensure that ALL valve bridges are correctly seated onto the valve stems will cause interference between the pistons and the valves, resulting in damage to the engine.
Install valve bridges (5) to the valve stems. Ensure that valve bridge clips (9) are correctly located.Note: Install used valve bridges in the original location and in the original orientation. Ensure that the valve bridges are correctly seated on the valves. New valve bridges may be installed in either orientation.

If necessary, use Tooling (A) to rotate the crankshaft so that number one piston is at top dead center on the compression stroke. Refer to System Operation, Testing and Adjusting, "Position the Valve Mechanism Before Maintenance Procedures" for the correct procedure. Install Tooling (B) through Hole (W) to lock the crankshaft.Note: Do not use excessive force to install Tooling (B). Do not use Tooling (B) to hold the crankshaft during repairs.
Remove Tooling (B).
Failure to ensure that the crankshaft is positioned at 60 degrees after top dead center will result in interference between the pistons and the valves. Failure to ensure that the crankshaft is positioned at 60 degrees after top dead center will result in damage to the engine.
Use Tooling (A) to rotate the crankshaft in a clockwise direction and position the crankshaft at 60 degrees after top dead center.
