HANDLE ASSEM. 4L6465 - Caterpillar

Hand Fuel Priming Pump (If Equipped)
If the engine's fuel system is run dry, fill the fuel tank. Then prime the fuel system in order to remove any air bubbles from the system.
Do not loosen fuel lines at the fuel manifold. The engine components may be damaged and/or loss of priming pressure may occur when the fuel lines are loosened.

Follow these steps in order to prime the fuel system:
Locate the red selector lever knob for the fuel priming pump.
Turn the red selector lever knob away from the fuel filter base by 90 degrees.This is the PRIME position.
Operate the priming pump's plunger in order to fill the final fuel filter. Continue until you feel resistance.Note: You may need to pump the priming pump for 25 times or more in order to fill the fuel filter. Furthermore, you may need up to 75 pump strokes to fill the fuel manifold.
Push the plunger and tighten the plunger in a clockwise direction. Tighten the plunger by hand.
Turn the red selector lever knob back to the RUN position.
After you pressurize the fuel system, promptly crank the engine.Note: Use the engine starting procedure. Refer to Operation and Maintenance Manual, "Engine Starting" in the Operation Section .Finding The Top Center Position For No. 1 Piston

Top Center Bolt Location (Typical Example) (1) Top center bolt. (2) Timing hole. (3) Flywheel housing.Note: Timing hole (2) can be in one of two positions:
the left, front face of the flywheel housing
the right, front face of the flywheel housing
Remove the plug from timing hole (2) from the front side of the flywheel housing.Note: Turn the engine with the four large bolts on the front of the crankshaft. Do not use the eight small bolts on the front of the crankshaft pulley.
Put top center bolt (1) through timing hole (2) in the flywheel housing. Turn the flywheel in the direction of normal engine rotation. Turn the flywheel until the timing bolt engages with the hole in the flywheel.Note: If the flywheel is turned beyond the point of engagement, the flywheel must be turned in the direction that is opposite of normal engine rotation. Turn the flywheel by approximately 30 degrees. Then turn the flywheel in the direction of normal engine rotation until the timing bolt engages with the threaded hole. When the No. 1 piston is at the top center position, this procedure will remove the play from the gears.
Remove the valve cover for the No. 1 cylinder head.The inlet valves and the exhaust valve for the No. 1 cylinder are fully closed under two conditions:
No. 1 piston is on the compression stroke.
The rocker arms can be moved by hand.If the rocker arms cannot be moved and the valves are slightly open, the No. 1 piston is on the exhaust stroke. Note: Refer to Testing And Adjusting, "Crankshaft Positions for
