Figure 6-2 Injector Installation Surface
6.5 Installation on the Engine
Follow these guidelines to prevent damage to the injector and its electrical
interface during the build process.
Lubrication
• Apply a light coating of lubricant to the lower injector seal ring. ISO
10 light mineral oil or equivalent is recommended. (See Table 6-2)
Additional lubricants can be evaluated by Delphi for injector sticking
and corrosion and added to the approved listing.
• The preferred technique is to apply the lubricant to the sockets the
injectors are being installed into, rather than directly to the seal ring
itself. This will help minimize the possibility of injector
contamination.
Caution:
• Avoid applying lubricant over the director plate holes – this may
restrict injector flow. Do not dip the injector tip in lubricant.
Fuel rail
• Rock the rail back and forth to seat the assembly.
• The maximum injector axial loading shall not exceed 800N.
Warning:
• Never hammer down on the fuel rail to install it.
