Cummins 4BT – Throttle Control Lever Connection

When connecting the cable/rod to the control lever, adjust the length so the lever has stop-to-stop movement.

Adjust the length of the cable/rod to the mechanical shut down lever so there is stop-to-stop movement.

Fill the engine with clean 15W-40 lubricating oil.
NOTE: The total oil system capacity, including lubricating oil filters is:

Fill the cooling system with a premixture of 50 percent water, 50 percent ethylene glycol base antifreeze and
DCA4 corrosion protection. Refer to Procedure 1-06.
NOTE: The total coolant capacity (engine only) is:

Caution: Installation of the radiator cap at this point is critical to proper purging of air trapped in the cooling
system. Improper purging of air from the cooling system will result in engine damage from overheating.
Perform a final inspection to make sure that all hoses, wires, linkages, and components have been properly in­stalled and tightened.

Make sure the fuel is shut off by removing the wire from the fuel solenoid or the mechanical fuel shutoff is in the
“OFF” position. This is necessary to prevent the engine from starting during the lubricating oil rifle pressure charg­ing operation.

Caution: Do not engage the starting motor for more than 30 seconds. Wait 2 minutes between starter engage­ments to cool the starting motor.
Crank the engine until the lubricating oil pressure gauge indicates a positive pressure.

After pressure is observed, connect the wire to the fuel solenoid.

Prime the low pressure fuel system by opening the bleed screw.
Operate the plunger on the fuel transfer pump until the fuel flowing from the fitting is free of air.
Tighten the bleed screw.

Operate the engine at low idle for 2 to 3 minutes.
Warning: Do not remove the radiator cap from a hot engine. Hot steam can cause serious personal injury.
The engine coolant tem perature m ust be below 50°C [122°FJ.
Shut off the engine and wait 5 to 7 minutes for the lubri­cating oil to drain to the lubricating oil pan and check the
lubricating oil and coolant levels again.

Operate the engine at 1000 to 1200 RPM for 8 to 10 minutes. Check for proper operation, unusual noises, and
coolant, fuel or lubricating oil leaks.
Repair all leaks and component problems. Refer to the appropriate procedures.
Refer to Section 8 for the Engine Run-In and Test Procedures.
