Repair Procedures: Installation
WARNING:
- Be sure that the low pressure fuel hose quick-connector (A) is completely connected to the high pressure fuel pump by the locking sound.
- Double-check the complete connection of the low pressure fuel hose to the high pressure fuel pump by pulling it after connecting.
- Be sure to install the high pressure fuel pipe (B) to the specified torques.
- Because fuel leak may cause fire, thoroughly inspect leakage of all fuel line connection parts at engine start condition.
NOTE:
- Before installing the high pressure fuel pump, position the roller tappet in the lowest position by rotating the crankshaft. Otherwise the installation bolts may be broken because of tension of the pump spring.
- Do not reuse bolts.
- Do not reuse high pressure fuel pipe.
- When tightening the installation bolts of the high pressure fuel pump, pre-tighten them by hand first, and then tighten them in turns to the specified torque in small steps (0.5 turns).
- Install the component to the specified torque.
- First, secure the fasteners in place by pre-tightening them by hand. Then, tighten them to the specified torque using a torque wrench.
Bolts or nuts not tightened in a straight line with the matching bolt holes or fittings may cause fuel leakage due to broken threads.
- Note that internal damage may occur when the component is dropped. In this case, use it after inspecting.
NOTE:
- Apply engine oil to the O-ring (A) of the high pressure fuel pump, the roller tappet (B), and the protrusion (C). Also apply engine oil to the groove on the location where the protrusion (C) is installed.
NOTE:
Use the special service tool [SST No.: OK353-F6100] to install the high pressure fuel pump.
- Install in the reverse order of removal.
