CYLINDER GP-STEERING 1303011 - Caterpillar

Illustration 1 g01241414
Typical example
Loosen the banjo bolt (1) on the secondary fuel filter base (2) .
Illustration 2 g00898194
Hand priming lever for the priming pumpNote: If the drive cam of the fuel priming pump is in the position of maximum cam lift, the priming lever will not operate. Rotate the crankshaft by hand one revolution.
Operate the priming lever on the priming pump until fuel flows out of the banjo bolt (1) .
Tighten the banjo bolt (1) to a torque of 23 N m (17 lb ft).
Illustration 3 g00905440
Air inlet heater on the air inlet manifold (3) Flare nut
If the fuel line for the air inlet heater has been drained, loosen nut (3) . Operate the priming lever on the fuel priming pump until fuel is free of air from the fuel line.
Tighten nut (3) to a torque of 22 N m (16 lb ft).
Illustration 4 g00898197
Fuel injection nozzles in the cylinder head (4) Flare nutNote: Damage to the fuel injection pump, to the battery, and to the starting motor can occur if the starting motor is used excessively to purge the air from the fuel system.
Loosen flare nuts (4) for the high pressure fuel lines on two fuel injection nozzles.
Operate the starting motor until fuel is flowing from the fuel lines.
Tighten flare nuts (4) to a torque of 22 N m (16 lb ft).
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.
The engine is now ready to start. Operate the engine at low idle for a minimum of five minutes immediately after air has been removed from the fuel system.Note: Running the engine for this period of time will help ensure that the pump is completely free of air. Damage to the internal parts of the pump, which is caused by metal to metal contact, will be prevented. If the engine stops or if the engine runs roughly, check for air in the fuel system. If air is in the fuel system, leakage in the low pressure fuel system probably exists.
