Remove and Install Fuel Injection Pump
CAUTION:
X9811-UN: High-Pressure Fluid
Escaping diesel fuel under pressure can have sufficient force to penetrate the skin, causing serious
injury. Before disconnecting lines, be sure to relieve pressure. Before applying pressure to the system,
be sure ALL connections are tight and lines, pipes and hoses are not damaged. Keep hands and body
away from pinholes and nozzles which eject fluid under pressure. Use a piece of cardboard or wood,
rather than hands, to search for suspected leaks.
If ANY fluid is injected into the skin, it must be surgically removed within a few hours by a doctor
familiar with this type of injury or gangrene may result. Doctors unfamiliar with this type of injury may
call the Deere & Company Medical Department in Moline, Illinois, or other knowledgeable medical
source.
Any time the fuel system has been opened up for service (lines disconnected or filters removed), it will be necessary to bleed
air from the system. (See Bleed Fuel System in this group.)
