KIT-CROSS & BEARING 7X4960 - Caterpillar

Contact with high pressure fuel may cause fluid penetration and burn hazards. High pressure fuel spray may cause a fire hazard. Failure to follow these inspection, maintenance and service instructions may cause personal injury or death.
Refer to the Operation and Maintenance Manual , "General Hazard Information and High Pressure Fuel Lines" before adjustments and repairs are performed.Note: Refer to Testing and Adjusting Manual , "Cleanliness of Fuel System Components" for detailed information on the standards of cleanliness that must be observed during ALL work on the fuel system.Ensure that all adjustments and repairs are performed by authorized personnel that have had the correct training.
Do not crank the engine continuously for more than 30 seconds. Allow the starting motor to cool for two minutes before cranking the engine again.
If air enters the fuel system, the air must be purged from the fuel system before the engine can be started. Air can enter the fuel system when the following events occur:
The fuel tank is empty or the fuel tank has been partially drained.
The low pressure fuel lines are disconnected.
A leak exists in the low pressure fuel system.
The fuel filter has been replaced.Hand Fuel Priming Pump
Use the following procedures in order to remove air from the fuel system:
Ensure that the fuel system is in working order. Check that the fuel supply valve (if equipped) is in the "ON" position.

Typical example
Operate the fuel priming pump (1). Count the number of operations of the fuel priming pump. After 100 depressions of the fuel priming pump stop.
The engine fuel system should now be primed and the engine should now be able to start.
Operate the engine starter and crank the engine. After the engine has started, operate the engine at low idle for a minimum of five minutes, immediately after air has been removed from the fuel system. Note: Operating the engine for this period of time will help ensure that the fuel system is free of air.Note: Do not loosen the high pressure fuel line in order to purge air from the fuel system. This procedure is not required.After the engine has stopped, you must wait for 60 seconds in order to allow the fuel pressure to be purged from the high pressure fuel lines before any service or repair is performed on the engine fuel lines. If necessary, perform minor adjustments. Repair any leaks from the low pressure fuel system and from the cooling, lubrication or air systems. Replace any high pressure fuel line that has leaked. Refer to Disassembly and assembly Manual, "Fuel Injection Lines - Install".If you inspect the engine in operation, always use the proper inspection procedure in order to avoid a fluid penetration hazard. Refer to Operation and Maintenance Manual, "General hazard Information".Electric Fuel Priming Pump
Ensure that the fuel system is in working order. Check that the fuel supply valve (if equipped) is in the "ON" position.
The electric fuel priming pump will operate for 90 seconds. If necessary the electric fuel priming pump can be stopped during the
