 WARNING 

When servicing the engine, do not use a remote starter switch or other means that would engage the starting motor to rotate the engine on a high pressure common rail engine. Using the starter motor can create highly pressurized fuel in the fuel system.  High-pressure fuel spray can penetrate the skin, resulting in serious personal injury or death.  Use a hand barring tool to rotate the engine for servicing the engine. Always loosen the pump to rail fuel line at the rail to vent the pressure after rotating the engine. Keep hands clear of the line when loosening and wear appropriate eye protection.

Front Barring

  • Insert the 3/4 inch breaker bar into the 3/4 inch drive located on the front of the crank nose. Rotate the engine clockwise, when viewed from the front of the engine.

Rear Barring

  • Remove the plastic cover in the flywheel housing. Insert service tool, Part Number 4919092, into the flywheel housing.  Use a 1/2 inch breaker bar and rotate it counterclockwise, when viewed from the front of the engine.
