burned by the heated engine. Before performing fuel line work, check the common
rail pressure and engine temperature by using the failure diagnosis device.

separate containers and marked for safe management.

strength, shape, and torque according to their assembly position. Please divide and
store them accordingly to these characteristics.

reassembling parts. Use compressed air to clean the oil holes.
